Mountain Bike Brake Test - Temperature Testing. How Hot is Hot?
HTML-код
- Опубликовано: 5 сен 2024
- In this video we test three popular brakes and share results from lots of days testing them on some of the steepest descents we could find. Our goal was to see just how hot brakes get during a long downhill and how big of a difference there is between brands.
TRP DHR Evo brakes with thick 203mm x 2.3mm thick rotors
Shimano XT brakes with 203mm IceTech Freezah rotors
SRAM Code RSC brakes with 200mm rotors
While we were hoping to see some major differences in temperatures, the field was a bit closer than we thought, however the power, lever feel and consistency were the biggest notable differences.
If you ever wanted to know how how your brakes get, give this video a watch. It was a bit more challenging than expected, took us several tries and locations to make, but we're happy with what we learned, even if it was different than what we set out to originally test.

At 280 pounds and riding fairly steep trails in Idaho I love my TRP's!!!
Ye i want to buy Them. First i wanted the Hope because the pressure Point adjustment but i rly Like the 2.3mm thickness and Design From trp
Had Code rsc with 220/200 and Hope v4 with 225/200mm Rotors. switched to Trp dh-r evo with 220-203 Rotors. These trp Brakes are the best i Ever Had. Insane Power and no fading. Even After 1000m vertical drop they performed perfekt. I love them, especialy the Gold Color 😅
Fantastic work done in this one! - - Test Results:
1. TRP - Best in braking power and feel with least amount of heat to caliper 205.
2. Shimano XT - Second coolest temperature 210, harder to pull than TRP in extended braking but still very powerful.
3. Sram Code - Lost its famous for modulation in extended braking. Highest temperature of 285 degrees, lost braking power, most hand pump.
Thank you
Would love to see the difference in heat with different pad materials, finned or not, ice tech or full steel rotors, and rotor size. Great video though!
Agree with you thoughts. TRP uses a 2.3 rotor while the shimano and sram use a 1.8mm thick rotor. The thinner the rotor the hotter the caliper gets as the pistons touch it. Which is a testament to the rotors that shimano uses with the fins, I guess they really work because the XT was closer to the TRP in temperature.
This test is really pointless. They are pointing a heat gun at the caliper, but that temp doesn't reflect the pad or rotor temp, where fad actually happens!! You could have a caliper temp 50% higher, but it could still have less fade based on the pad material!! The pad and rotor temp will mostly come down to rotor diameter, thickness and built in cooling in the design (fins ect.). I suspect this test is just a paid promotion for TRP! Don't get me wrong they make great brakes, but this test is just ill conceived.
out of all brakes i've tested, TRP is the best one for me, this modulation and power is just amazing and they are durable as hell.
Presented by TRP.... Am I the only one that saw this? I've never ridden TRP so I cant comment. I have Code RSC and I had go up to 220/203 rotors. I was smoking the rotors on anything smaller. I went with the Magura E-Bike rotors. I feel that any set of brakes will do better with 220/203 rotors. Try big rotors before dropping a lot of cash on new brakes.
Hey Duane. We had originally planned on making a different video altogether but after riding each brake back to back the direction changed. And while TRP is a presenter of our RUclips Tech Test Series, our results wouldn’t have changed even if SRAM was a presenter. We chose to partner with brands who’s products we like and believe in. Magura also makes solid brakes and like others, have their own quirks and defining characteristics, but they would have likely been high on the list with Shimano. Above all else we value open and honest testing and review process and do our best to report accordingly. Staff and non-staff testers all would pick TRP for all out power on their personal bikes.
Are you adjusting the emmisivity setting on that IR gun? Black is waaayyy different that silver You may be off by like 30% or more just in the measurement alone
Some pad and rotor compounds perform better at higher temps. After i switched from Shimano, Sram and now to TRP rotors (sram code rsc with metallic pads), the performance improvement was instantly noticeable on long descents. I would assume the TRP brakes with TRP rotors would be that much better. But frankly, i love the ease of service on the Sram's, the Bleeding Edge gives a perfect bleed every single time. Something i could never get with Shimano
I found my way from SRAM to Magura to TRP. TRP is easy to work on reliable and strong in all categories of modulation, power, lack of brake fade. I actually think I could have gotten away with Slate EVO and still been ecstatic with the performance. Cool trails, I was trying to figure out where you were and could not!
That was great. I hear good things about hayes dominions. Hayes vs trp shootout ?
I run Sram codes and have done for 3 years now but run Magura 220mm MDR-P disc front and rear and carbone lorraine pads VXR pads and perform better than Sram sintered which are so good on my Specialized Kenovo and they run cool all summer and are great trail braking and great feed back.
I’ve ridden code rsc and Shimano Saints. I switched over to TRP Evo’s and prefer them over both shimano and the codes. It would have been cool to test the magura’s and hopes also. Great video guys!
Thank you very much
I love TRP's, I even pick a set for my pure XC bike, the thing is that even the weight it's similar to the 2 piston XTR's, but they're way more powerful and better feeling. Great video guys.
very cool test. unique, haven't seen this angle before, which is a bit of an achievement in the mtb space!
Thank you very much!
Rotor thickness makes a difference too do you think you can compare SRAM & Shimano's 1.8mm thick rotors to the thicker SRAM & Magura 2.0 thick & those 2.3(?) thick from TRP please?
Could also throw in pad materials in this test, I would like to know if race labeled pads help in keeping heat down...
Yes for sure. More to come!
@@TheLoamWolf i have a difficult time w/ that kind of thermometer on shiny/reflective surfaces such as Al heat-sinks. the readings fluctuate tens of degrees based on the thermometer's orientation.
i have better results using a probe thermometer (no, not the ones for cooking :} )
great video
They also forgot to mention that the shimano and trp brakes use mineral oil where the sram brakes use dot fluid which can operate at higher temperatures for longer which is why they use it in motor vehicles for years and years without any issues. Like when was the last time you bled the brakes in your car? I haven’t bled my codes in three years. Never overheats, way better performance, less maintenance. I have to bleed my XT’s every 6 months at least and do a lever bleed on them about every five to ten rides to keep the random bite point away. My XT any of them are nowhere near as good as my codes but it’s ok because they’re a lot cheaper than codes and nobody rates trp except this these guys. Good luck finding a good review anywhere else or find a pro without a brake sponsor running them.
Im 280lb on a levo and the magura mt7 with 220 mdrp rotors have been hands down the best brakes ive had to slow my big ass down , tl were stock, then had code r, shimano 4 piston xt and now the mt7 🙌
Thanks for sharing.
I did, and I know that my Sram Centerline rotors got to around 260-280°C (brown oxidation with some spots turning blue), but since I hanged to 4(f)/2(r) piston brakes and thicker (Magura) rotors, they barely even got any coloring to them (under 200°C), even though I rode much steeper and longer descents since then 😅
Awesome feedback thanks!
I think some of it depends on what you are looking for in Your brakes. We don’t have long down hills where I live, so between the Sram and Shimano I prefer the Sram because I can modulate them better. Shimano seem to be on/off. A good friend of mine, who rides the same trails, swears by the XT brakes. In your test I could see how you would want the most consistent stopping power. Thanks for the video
Thanks a lot for the comment and we always try our best to relay our personal experience but also try and say who may appreciate other products as we all have different styles and terrain! Thanks for watching.
At 575 degrees Fahrenheit, steel turns blue. At 800 degrees Fahrenheit, steel turns grey. Above 800 degrees Fahrenheit, steel produces incandescent colors. Between 1000 degrees Fahrenheit and 1500 degrees Fahrenheit, steel turns an increasingly brighter shade of red
I was asking myself that this morning while I was riding some downhill in the Santa Monica mountains.
It would be interesting to see Shimano XTR magnesium vs TRP evo's stainless steel caliper. XTR use a magnesium caliper to not only reduce weight but to keep them cooler. It's interesting how the one guy says @05:32 that he's pulling harder with lost modulation on the sram codes, giving greater hand pump. Then the other guy @08:01 says that Sram brakes get a bad wrap but his colleague @08:12 gives body language that he doesn't believe what he's saying. Sram seem to be the worst in this test and got close to 300 degrees. Which is really hot and gives heavy hand pump and can lead to DOT oil leaking. Seems that the XT and TRP use regular mineral oil, which may help in cooler temps.
What about magura, hope, formula? I personally would 100% appreciate an overall comparison between some xtr, code rsc, dhr evo, tech 3 v4, mt7 raceline at the very least and would be cool to see formula and others thrown in the mix.
An xc spec version with all the same manufacturers would interest me but be of no practical use hence the request for the big 4 pot comparison.
Why not tha Saints???
I Run Saints 203Floaters And MTX Pads Golds/F Reds/R Run 3wt. Fork Oil Work Really Good 😎 Ride CF Warden Vancouver . Proper Bleeding and Fluid Is Important.
Thanks for this, I’ve got a Sight VLT coming in October (hopefully) that I was going to swap the Codes out for Shimano but now the weight of the bike, I’m gunna give the TRPs a hard look.
SRAM have just released their thicker HS2 rotors which have more surface area to dissipate heat. Would be interesting to see what kind of improvement they make and if they can get anywhere near the 2.3mmm thick TRPs!
Also, I've heard other reviewers complain that the bite point can move around on the Shimanos as they heat up. Was there much of a difference here?
i made the upgrade from 200 centerline sram to HS2 on my LEVO. very lttle improvment with Galfer EBike pads..i am thinking magura 220 rotors now
Cool vid - but no Maguras in this experiment?
I replaced SRAM with Maguras - the Maguras feel awesome, I'll never go back to SRAM!!
A more accurate way to analyse this would be to have the same bike for all the different brakes and also the same rider to minimise the effects of the bike on brake use (handling, suspension, weight etc, which will influence how you use your brakes)
To minimise on arm pump it would be ideal to have a much smoother trail where braking points can be much more repeatable each run!
Measure temperature before and after the run and do more than 1 Run on each brake.
Use same pad compound for each brake (metallic/organic/semi) could even go to the extend of using let’s say a 3rd party pad manufacturer to minimise the effects of pad compound during the test
Also measure rotor thickness and amount of pad lost after each run
Also would be ideal to try and reduce rider fatigue as much as possible so that feeling of how the brakes work doesn’t get too affected negatively after each run
Use a control rotor from a 3rd party brand and compare its performance vs the brake brand rotor
Analyse with a bleed how did the test affect the oil inside the system
This I know it’s a very extensive test to do but it would be so interesting to see a much more in-depth review and richer data to support the veredict!
Heck there could even be influences on the results if center lock rotors are used vs 6bolt ones and that’s on top of footing rotors or full one piece metal rotors…
This would be so crazy to do and would take like 2-3 weeks but could give some damn interesting info of how this brakes perform
Yeah ultimately we just wanted to have some fun, see how hot the brakes get and not be too serious…outdoor testing is never perfect as tires will start to wear after laps which changes braking performance, the trail conditions change as dirt gets moved from more traffic and erosion, creating a totally different run, line changes could vary… and the list goes on. Which is kinda why we just decided to have some fun.
You should also list the oil being used in the system. I would add Hope brakes into the mix as well.
TRP and Shimano use the common mineral oil and Sram use DOT oil.
One thing to take into consideration, once brakes start to lose power, you start using them more to avoid gaining speed, so they heat up even more from there, at least I think that's how it works.
Wonder if the thicker rotors on TRP helped?
9:16 "The subscribe gutton!" (^;
The idea is good but the methodology is quite poor. In any research study, you want to eliminate the variables and biases.
With different bikes, bike weights, rider styles and rider weight, the conclusions are poorly estimated. More so, if the researchers have a bias toward one or another brake, the results might get skewed.
I recommend one bike, one rider, one straight trail, road preferred and speedometer to maintain same speed. Also, same rotor size and same number of pistons.
Change brakes and test each one separately.
The outcomes would be more significant.
Cheers.
I've always wanted to do a long downhill at night to see if those suckers glow.*
*I use Shimano so it'll be fine because they're unarguably, indisputably hands-down better than anything else.
They probably won't even get that hot, due to Shimano's all-round superiority, including heat dissipation.
Fite me.
A note on the IR thermometer - it's emissivity dependent. i.e the color/finish of the surface makes a big impact.
Often bare metals act as mirrors to IR, so you're probably not measuring the rotor temperature, but whatever the laser sight would bounce to.
Take the IR gun and point it at random objects that are at room temperature to see what I mean, this only gets worse at higher temps.
Thanks! We learned a lot not only about brake temps but about IR thermometers in this process. We may have to do a round 2 in the future!
I had the smart idea of touching the discs once, it was only breif, but it was rather hot. Why I decided to do that, absolutley no clue, fingers were fine ofc for the short touch on them. I guess I just wanted to see how hot they got, but didnt expect them to be as hot as they were.
Excellent fun and temp comparison. Measure rotors or calipers?
Have had MT5 4 piece and MTX red pads.. magura 8.R race pads run too hot for long braking, though too on/off power and poor modulation .
Now have both Galfer W 223 rotors and mtx gold ceramic pads... take little longer to warm like true race brakes but are amazing powerful and modulating when warmed a little and zero fade. Will test further. Recently changed to Shigura XT levers...wow. power + modulate.
Quick note ... these thermometers have a problem with shiny/reflective surfaces. To get a good reading, you should put a black thermal pad on the brake.
Still, interesting, but it seems that you got consistently lower temp on the shiny XT.
Yep something we have learned since! Always learning and looking for new ways to have fun and test stuff. So, guess we’ll have to try again.
Yeah, I was using one and numbers just didn't add up because I tried to measure something chrome plated :), which is an extreme worst case scenario for these :)
Maybe you could use those thermal stickers they use on dirt bike radiators. Not sure about the range, that might top out at 100-110C
Yeah brakes get hot, they're supposed to. Maybe in the next video do a comparison of aftermarket brake pads comparing heat resistance(fade), modulation and noise. I wouldn't be too concerned about reading caliper temperatures unless you can put a temp probe right on the pad itself. Then you could possibly use that data to see if the pads are running in the optimum temperature range per the manufacturer.
That’s a good idea! We’ll get some more brake pads and install them to see how they do.
Good video, but to be fair all 3 set of brakes should have been running the same rotor thickness otherwise we all get to a conclusion which is not 100% accurated, shimano 1.8 mm rotors obviously are not going to dissipate the heat as well as 2.3 mm TRP or Sram 1.85 mm centerline, which I think you had. A part from that pad compound is another factor to have in consideration. I'm not saying that TRP are not good,but to have a more accurated comparation all three riders should have had 3 runs with all 3 diferent bikes due to the difference in body weight and all 3 bikes running all three sets of brakes and the same thickness rotors, of course there're some other factors that can influence on how much one uses the brakes and how long, just to slow one down, for instance, tyres, with,compound,carcass, etc.
In short, you should have reduced the variables to the minimum expression so the outcome was more reliable otherwise, we will never know if those temperatures and the drop in performance of the shimano and sram are mostly due to the rotor capacity of dissipateing heat or that inconsistency is due to lever/hose/caliper when they are working hard under high temperatures after a demanding and long descent
I only once cooked my brakes so bad the rear rotor was blackish and doing weird noises...But that was in Chatel in a very high speed track and a 2 pot brake. Never again had that problem or being close to...
If you like SRAMs infamous modulation but want more reliability, I highly recommend this set up or something similar:
I currently ride
SRAM G2 Calipers and Levers
Galfer Rotors single unit, 2mm thickness (slightly changed the bite point)
MTX Race Red ceramic pads. Offers the same or better bite/grip like the sintered pad but is very quiet like the like the organic pad.
I suggest you pick these up and test them for yourself.
I swapped my code r for hope e4 love them for the trails that I do
Would love to see stock TRP pads up against MTX, Trucker Co, Galfer, Kool Stop and the likes
Did you just use the rear brake coming down? Never saw a front brake temp comparison. Also some pads work better when hot. A material comparison would have been nice My Magura race pads are incredible when Hot vs the stock pads.
Enjoyed the video
Maybe you don't need a front brake on e-bikes. Also, outside of the caliper is not brake temp.
@@-tr0n No it's that they think the left lever is a clutch on their moped.
@@paradox963 😂😂 that’s a good one.
These trails are much too steep for only using a rear brake. We measured rear for consistency and since that brake is the hottest and gets used more.
other brakes I would like to see:
Formula Cura 4
Trickstuff Maxima, I have chatted with people who have Dirritisima brakes, and they love them, apparently they beat Formula Cura 4 in power and feel.
and also various rotor combos.
I would like to see BrakeStuff Punch rotors that haven't been tested by many yet. They have made thick rotors long before the big brands did. they claim the tiny venting holes combined with a thicker rotor give better cooling.I see Reverse claims big holes and a thick rotor does that. so some conflicting info. but those RReverse rotors in question are prototypes, and I don't know if they meant in relation to their other rotors or in general, cus things are more complicated than this, I don't know what they used for testing or if it was the same pads or brakes.
how does the magura that was previously reviewed compare
It’s been a while since we’ve ridden them, but we do really like magura brakes as well. They would be high on our list of brakes worth trying.
Reliability and durability is what im looking for, shimano would be my pic
Mmmm, i think this is a good test, however not convinced by the results…the only thing that creates heat is friction between the pads and rotors…then heat is dissipated by the rotor. Id be more interested in seeing how different rotor styles dissipate heat, and what types of pads are more consistent (metallic, organic, aftermarket pads like MTX, etc). And perhaps a more controlled setting like having a motor in a lab (rider style definitely had an impact on results).
I have the Shimano Saints 4 pistons with the TRP rotors and Im about 220lbs. The Saints, when cold, feel like its at full 100% locked or 0%. Once they get hot the feel and consistency gets better. I find myself having to readjust braking points often when Im riding cause the bite point changes. Its getting quite annoying.
Im keeping the TRP rotors. They dont fade as much as the srams and ice techs. Will probably get the TRP DHR Evos soon. Heard nothing but great reviews from them.
I bought a set of TRP Rotors back in 2019 and noticed the gap from the wear indicator was deeper than the rotor I bought in 2021. Not sure if they raised the gap on purpose so we would have to change em out more often. 🤔
I have had sram brakes since they were avids. Got some trp slates on last bike, guess I would change to metallic and bigger rotors before I went back to my codes.
I recently upgraded to Magura MT7s with their ebike rotors on my Slash. At 220lbs, I was tempering the rotors yellow+ on the stock Code Rs every time I went to a bike park.. and it was scary how bad they faded at Mt. Killington, the upgrade needed to happen
Why the XT from shimano rather than the saint which is more in the category of at least the code RSC? Also things like pad material and disc temperature would have been interesting.
The pad material was what I was wondering because as far as I know the organic pads come standard for shimano, I'm running the metallic pads which although are more noisy, work harder for longer
@@tippy35075 I got metallic pads with my saints.
On steeps I brake harder on the rear and Metallic pads squeal badly when hot. I went back to Organic pads but replace them frequently. I still run Metallics up front as they feel more firm . I have recently switched to Kool Stop Reds and like them much better than the Shimano organics.
This is on Saints with Shimano fluid.
Because TRP were paying for the video (see first few seconds of video).
it would be more interesting to test with the same rotors. of all 3 the sram rotors were the worse, trp the best. its makes most difference imo.
What you say makes sense but you can't run TRP rotor on a sram brake, they are 2.3mm and the largest a sram fits is 2.0. Shimano can run a 2.3 mm TRP rotor, I know because its a hack I use and they play well with each other and performance is amazing! Sram and shimano use 1.8mm rotors but shimano claims their ice tech rotors keep the calipers cooler at high temps and some shimano's have the cooling fins as in this video. I guess they work as they were not even close to the heat of the sram brakes.
Video about disc brakes, shows the discs for about 1/2 second.
Great brake comparison. What speed sensor/bolt setup did you run on the turbo levo trp setup?
Yea rotor change even in same size can make a huge difference I noticed that with stock resin only Shimano rotors 160, 180, I cooked those badly, they got really hot, after braking after one hill, swapped to hope floating rotors and problem solved until I rode more of this type of riding, then they started to warp, same with 180, 230mm combo, so now I have 223mm TrickStuff Daähle I got secondhand. An issue with floating rotors is after few years of use they might start to creak. So I will stick with regular rotors.
Hey LOAM RANGER, what computer and mount is that?? I like how it's mounted BEHIND the bar for protection!
Try a formula cura 4 brake.
Guys, come on. Check your viewer geographic. Realise Fahrenheit only gets used locally, add celsius to the vid. You're a professional media platform pumping out content to the entire world. Don't lag behind your own succes ;).
Alright alright… you got us there, didn’t even think about that. Next time!
I swapped my sram guides for hope tech E4's, the guides are definitely more comfortable on the lever but the hope's have a similar progression but at max are awesome, never tried trp's though
Mugura next please!
No shimano Saints?
they should have been testing the XTR and the RSC
Is TRP sponsoring this video? Is this really an unbiased test?
Why would you only take temps on the rear caliper? Different riders aren't going to treat the brakes the same way. Next time, take temps front a rear. Also, what is with the "dragging the brakes at 10mph"? That can't be a fair test unless we know the wattage being put the pedals.
IR temp sensors are not able to accurately read temp from light reflective surfaces unless they are calibrated to do so. This should have been done with a surface temp thermocouple probe. It would have been faster to register and exactly the real temp
Well shoot! As we said, we’re not scientists haha, just trying to have some fun and share some impressions on brakes back to back on the same trails. The temps were just a fun bonus…but, now you’ve got us wanting to invest on a surface temp thermocouple probe.
Should have had amount of pistons displayed for each brake tested
285 sram code????
The more heat the more energy it converts to heat so logically the most efficient brakes would be hotter converting the same amount of energy...
I think you guys deserve a PhD after your names. 😆
wtf is F
Why only measure caliper temps?
We measured rotor temps as well, during each of our 3 outings to make this video. When testing, and talking with brake engineers, we learned that rotors are a lot harder to get temps on because of the small surface area, the large heat sinks (each of the arms going to the mounting area) pull so much heat so quickly that rotor temps change so quickly. We could take a temp reading on the center of the rotor and 2 seconds later take one just above the arm and have a 35-degree difference. Furthermore, when we talked with the engineers, we learned that they primarily check caliper temps, and use stickers on them to get max heat because it's more reliable and repeatable.
@@TheLoamWolf thank you for the reply.. glad you were talking to engineers.
I know about the caliper stickers as they use them in motorcycle racing too (I do motorcycle trackdays). The fluid temperature is fascinating to me too but I suppose you can assume the caliper temp will be similar to the fluid temperature.
Great to see some people try and do something more scientific too 👌
sponsored by TRP....winnner TRP hahaha
Hey Justin, we've made a few other long replies to similar comments on this video. It wasn't necessarily a comparison test on which brakes are the "Best" but more of a fun experiment on brake temperatures. We did get a bit excited and off topic while discussing performance as a side bar, but we can't cheat the thermometer. There were runs where the Shimano brakes and rotors were coolest.
So to say there's a winner in this video we wouldn't necessarily agree with you. If we had to pick which brakes we would buy and put on our own bikes, which we tried to clarify, it would likely be the TRPs, even is SRAM had donated budget to cover the production cost of this video, our results and impressions would be the same. We hope that clarifies things. We're always as transparent and open as possible, which is why we include logos of brands that help us create videos, and TRP was confident enough in their product that they wanted to see how it went, with zero obligations.
Hey I’m new to mountain biking and I’m wondering what I should upgrade on my bike first
go out and break something on it first!
You should definitely upgrade skills first by watching a good, qualified instructor or better riders!
From there we’d say tires are high on the list! Quality rubber compound then suspension and brakes.
We’re going to make a video on this topic though! Stay tuned
Any touch points, pedals, grips, seat, just to get it feeling nice then do tyres and then brakes (if their not holding up)
@@ryanmission already have I’ve been riding every day for about an hour getting better and earlier today I ran into a a rock with my back tire and it popped
What did we learn... brakes get hot?
Simple thing, all brakes as shown do actually "work" in the real world, and are fit for purpose.
The 'science' on display was questionable at best, with each set of brakes being on a different bikes at the worst, so there isn't really any control being shown (like what types of pads were they all on etc?).
While I am not going to say that you all had a bias going into this, though what I will say, if you are going to clearly show that the video is "presented by TRP" at the beginning of the video (I'm going to guess there was money involved as a result, thus making the video really just looking like an advertisement for TRP), and they are the brand you are all eluding to being the best of the 3 with your temp gun and other comments throughout, on the outside looking in the 'results' are something that I will personally take with a pinch of salt.
Thanks for the comment Bob. Your observation of our 'science' is pretty much exactly what we said about the test at the very beginning and again at the closing of the video. It was a fun project and video we wanted to make and are well aware of the challenges creating a true scientific test in the wild. Even if we had the same bike, things like tire wear (affecting braking edge), changing trail conditions as erosion, dirt moving, line choice, ambient temp change all will come into play, but lab results vs in the wild performance is a whole other topic...
We have a number of partners, all of whom we believe in, helping us support our small team's ability to go out with video/photogs and create fun videos. We are and always will be as honest and straight up as possible, and while we don't doubt that it's hard to trust anyone these days, we maintain the right to be as open and honest with the brands and our viewers as that's a staple of our brand and who we are. That's part of why we brought the thermometer out. In fact the Shimano brakes did run cooler in some test runs, and we didn't cut that out. We always try to present our personal feelings and experience and also admit that what we like, prefer may not be what everyone else likes, and we do our best to say that and share who some products may be better, or worse, for. These TRPs are not for everyone, but we know we'd pick them whether or not they helped support our video series or not.
Take that for what it's worth, we hope it answers some of your questions and we absolutely understand the skepticism as so many other outlets, not just in MTB, are very much in the pay to play game, and while we do seek out brands who's products we believe in to help us fund content, they all know and respect we maintain the right to criticize or call out product weaknesses where we see them.
Thanks for watching.
I can now trust everything you say. SRAM brakes are HORRIBLE
Subjectively maybe, but that's not what the test is showing...
I know they get hot enough to burn the shit out of my leg haha
We’ve all been there. Ha ha
This test is really pointless. They are pointing a heat gun at the caliper, but caliper temp doesn't reflect the pad or rotor temp, where fade actually happens!! You could have a caliper temp 50% higher, but it could still have less fade based on the pad material!! The pad and rotor temp will mostly come down to rotor diameter, thickness and built in cooling in the design (fins ect.). Don't get me wrong TRP makes great brakes, but this test is just ill conceived. Any real test needs to use control pads and rotors or your trying to test too many variables at once! The caliper temp is a complete red herring, as you could use lot's of heat shielding to keep the caliper cool that reflected all the heat back onto the rotor and pads. I hope this channel does better in the future.
would be nice to see some magura mt7 against these 🤔
We’ll see if we can get a set
You called it kind of scientific but only measured the rear brake temps? It made it pretty much pointless…
Could you explain why it's pointless? Our curiosity, and desire to do this didn't stem from wondering how big of a difference in heat there was from front to back. It was how hot rear brakes get, since they get used way more.
Your test is not accurate due to the fact that numbers of tester 3 , reason different rider style , different body weights, different braking points , my opinion is, it should be one tester one trail .Thank you, in fairness to 3 different brake systems.
Each tester rode each of the three bikes. So essentially we did what you are suggesting, but 3 times. Hope that clarifies that? Each rider rode each bike to account for those differences.
You cannot do a comparison video like this when one of the tested makes were sponsoring the video - you lose any credibility.
Yes sram is crap
These results are flawed. First and foremost due to the TRP caliper being coated in a metallic/reflective finish, whereas the other two calipers are black or dark gray. This will yield large differences when measuring temperatures with an infrared thermometer. The results found with the reflective TRP's being consistently colder are to be expected. Additionally, the subjective sense of arm fatigue/pump is influenced a lot more by the lever position (angle), pad/rotor friction, piston sizes and lever design rather than temperatures -- unless there are catastrophically large differences in hydraulic fluid performance, which is probably not the case. So basically while this video is entertaining and interesting, the test results themselves should largely be dismissed.
Magura brakes are for men, not little fellas… DH and ebikes, all day, no worries. 👍🏼
