How wide are your tyres? (or _tires_ !)
GMBN Tech i ride a hardtail and my new tyre\tire is 26×2.35. (Maxxis high roller)
2.3
27.5 x 2.3
27.5x2.25
2,5 minion DHF up front and 2,35 maxxis aggressor out back with 27,5 inch wheels
3:51 ..thank me later
It's later.. thanks ✌️
@351
3:51
I'll thank you now
Thanks
I just wanna see the answer to the question in the title can u guys just add a time stamp to that
Yeah fair point honestly
It is always at the end of the video
4:00 got u homie
When you guys name the video some title that is ONE of many questions answered, the least you can do is add a time stamp so viewers can jump to that question.
What's the point of making a whole video then...
@@Albkiller22 well whats hes trying to say is he most likely searched for a video to see the right width of tires he should be running and wants a direct answer instead of having to watch the whole video. So the whole video isnt pointless but i would be nice to get a direct answer instead of having to watch or search through the whole thing which i what just happened to me.
@@epicalty8474 yeah but they earn money with watchtime so jumping to see a 1 minute part doesn't really support the channel
Giuseppe ahh your right that makes sense
@@epicalty8474 that makes sense if you really like their content and want to support them like I do
Really informative Doddy. These shows get better and better. Really appreciate the hard work you must be putting in to produce this material. Cheers.
Doddy, you are the Oracle of MTBs. Thanks for all the info and researching those bikes for me. Much appreciated. Love the look of the Whyte by the way, but you're right there's nothing wrong with the Yeti, so sticking with that for now. I demoed a YT Capra with 650b wheels and loved how it rolled over the terrain and my hardtail is 650b too.
As a roadie, I enjoy these every week! Doddy is so informative, and doesn't just answer the question, but gives personal insight that people might not have considered otherwise.
Keep up the good work!
Doddy, absolute legend! I’ve enjoyed reading your work over the years and no less enjoyable in video. Really informative and useful info coming out of your videos mate. Top Man!
Great vid as usual, great selection in the recommendations. Love my Whyte T130s, never let me down.
I love my Orbea Occam tr m10 2018. Just got it and love it. Light, fast, and playful. I also have a spare wheel set in plus that fits on the frame depending on where I am riding
Best show our there!! Awesome work Doddy... You can really tell how much effort you put in!! Keep it up!
As always, great video Doddy.
It would be really helpful if you all had your questions with timestamps in the video description. Thanks for providing such great information!
And again a great video on GMBN Tech. :-) Thanks, Doddy!
Doddy, soooo much content, mind blown! Thanks as always!
Im running a medium cage XT on 10-46, works perfectly!
The first question on the nukeproof i have the same bike and same issue i took it down to my local shop and it was a collapsed bearing
I like how Doddy seemingly pulls various items out of his ass
Really liking format for GmBn tech..Stellar job on air inforks and spacers.Best explanation I've seen..Question. Having rebound bouncy is it posibly to use it as a asset..for jumps bhops etc.Like a trigger after preloading shocks ...With the right timing you use less energy for these mtb techniques..Learn to tame the beast ...as it were.
I really resonate with what you said about the getting the biggest frame you can get away with. Even as a medium size rider.. This video has me seriously questing my choice of a size medium frame on my new purchase. Even with a 60mm stem w/6 degree rise and 40mm rise bars I still feel I'm over the front end with the reach too short. I'm 5.8 and and purchased a 2020 Ragley mmmbop with some modern slacker geometry.. bike is awesome maybe should have got a size large.
2.6" Smart Sam is a great tyre, rides really smooth on the road, plenty of footprint on the trails.
I Run 2.40 / 2.50 Excellent Traction To Weight Ratio 😎
My tires are 2.5 Minion DHF front and 2.3 Agressor on the rear on NOBL tr38 wheelset. But about the gear box. Wouldn't it also feel better having all the weight centralized and low (for handling purposes) i would love to hear doddys thoughts on where the weight is distributed
i'm really glad that you, Doddy, master of bikes, mentioned the Orbea Occam.
i can't wait untill next week when my Occam will arrive :D
Top info good man thank you!
I Love the New 2.6 Specialized Butcher Gripton Grid @ 20 PSI for only $60
Thanks for these qna the tyre tip is a good one will look at the contys
I like the Goodyear 2.6 Escape on the front, the cornering teeth are a bit small but it looks better for durability. The sidewall support at low pressure is tough to beat.
Great at explaining things this guy. Thumbs up
A medium cage 11sp XT RD-8000 GS will even run with an 11-50 tooth cassette in the back, although the chain tension is near borderline, and the B screw might reach its limit. You can pimp it with several upgrades though (Wolfcage, Goatlink, Garbaruk cage, etc), which all should improve things. I was running the XT SG with the massive 50 in the back for some time though, and it did work. I eventually upgraded to a Wolfcage though to improve shifting performance.
Commencal meta tr is a super underrated trail bike, with agressive geo + it’s a direct sale brand (the top model is $5000 AUD and it comes with a lot of good stuff)
Great presenting and content!
I’ve got a Whyte t130s. It rocks!
Some sewer covers in my town are across the street with longitudinal cuttings. If one ride a street bike it must pass diagonaly or the front wheel get stuck between. And its dangerous to do that because you cant always go sideway in traffic. So i chose an MTB for commuting in town (6km) and for fun ride. At my old bike i replaced 2.1 default with 2.2Continental. At my new bike i still use 2.1Maxxis but with lower pressure.
Great show Doddy!
I could watch doddy talk about tech all day,.
With yer old chap out?
Phantom Big Balls hahah funny that bro
Thanks, great one.
Ahhhh tecky tecky tech tech... This is what GMBN should have been like from the start boys. Keep up the good work Doddy. I feel like Johnny 5 - "input input!"
Hey Doddy, loving the Tech show and think you're doing an awesome job so keep it up!
I'm a tall guy too (6'4") and my Remedy 29er has a Reverb dropper post with 125mm of travel. I absolutely love my dropper post but feel like it's not quite tall enough for me. I'm considering a longer travel post, but my upgrade list for this spring seems to be getting longer with some other items wearing out (shoes and tires). I'm wondering if you think the upgrade would make a major difference or if I'm not really going to notice. Also, what are your thoughts on some of the lower price point dropper posts, like the Brand-X or any other recommendations you may have.
Awesome stuff :)
Great video again doddy
What the hell am I missing? How come you blokes only have 39K subs? I've learned loads from you, and by now you should have millions of subs!
199k
27.5 x 2.25 Schwalbe Smart sam, will try it tomorrow.
Hi Doody, love the content. Read a review on a pinion gearbox. Would love to know your thoughts. Are they going to be the next big thing? DI2 comparability? Lack of rear mech etc. Thanks, mike.
Hi guys, firstly, I'm new to GMBN and love your videos. Great job you're all doing 👌🏻😁👍🏻 I have quick question, I'm riding a Northtec Gravity 27.5 (Running a Rockshox XC30 TK/27.5 fork) currently with 2.10 tyres on front and back. The clearance at the rear doesn't allow me to go any wider unfortunately and I would like to know what you recommend the widest I should go on the front? Would going 2.60 front with a 2.10 rear be advised? Or would it be out of place? Thanx in advance and keep up the great work. 🤘🏻😎🤘🏻
Hey doddy, in regard of gearbox bikes you should definatly have a look at the effigear gearbox and cavalerie bikes. I really like the idea of the pivotpoint of the swingarm beeing coaxal with the sprocket. It would be the only way I would consider a gearbox on my bike. This combined with a low mounted rear shock would be perfect in regards of weight distribution.
Great show.
#askgmbntech Could you explain better positive and negative air chambers in suspension and what the differences and what differences it makes in suspension behavior (e.g. more negative pressure). Thanks, love the gmbn tech channel!
Good show as usual
Hi doddy I’m loving the videos but I’m thinking of upgrading to a 1x on my Grand Canyon al3.9 and I have come across oval chain rings what are the pros and cons of running these or should I just stick to circular ones thanks Finn
You often mention doing a lower leg service on forks, however the manual for my 2017 Fox 34 only mentions checking after each ride and an annual service - nothing about a lower leg service after x hours.
Should I be taking it apart and changing the oil? Or just following the advice in the manual from Fox? The same goes for my shock.
i ride 2.5" everywhere, except for my dirt jumper which runs on 2.4" Holy Rollers - that's the wide version and coincidentally the widest tyre i could squeeze in the rear anyway
Should I put a dropper post on my specialized chisel expert xc bike? And if yes, is there a dropper route through the frame?
I run up to 3 inch (77mm) and like to ride 50 mm on my touring bike.
At more than 110 kg I need the stability of a wide tire on multi purpose trail at slow speed.
Hi great video, thank's.
Im from Quebec, Canada and just bought a Large size Trek Farley 7 with 27,5 x 4,5 Gnarwal Bontrager tires on mulefut sunringle 80mm wheels.
Id like to have a summer wheels and tires kit to discover and slowly enjoy mountain biking.
What would you recommend for wheels and tires ?
I am 6' tall.
I have a question... What bike do you think will be better for trail riding... canyon nueron 7.0 or spectral 5.0 as there is only a couple of hundred pounds between them. Im 5'9" and inseam roughly 34" what would your recommended bike be aswell. Thanks love the channel 👍
Question I have the enve M60/40 boost wheels how wide of tyres can I go with?
Great work guys
Thanks CMOOREtbay !
I'm running a minion DHF 2.5 up front and a continental trail king 2.2 on the back 27.5 wheels
Doddy is right about the 3M tape. It's fantastic at frame protection. However, if you change your mind & want to take it off for some reason it can be a bit of a nightmare to get off. I'm speaking from experience here. So if you're going to use it try & make sure you're not going to want to take it off in the future.
I recently installed a new Sram gx 2X10 deralliur to my bike. But when it’s in the highest gear (smallest rear cog) the chain is way too slack until you pull it by hand. Any suggestions on what to do?
GMBN, don't you guys think it's high time you did an indepth review on different fullsuspension system to look out for when buying a FS bike and how they ride?
I've been in a state of dilema since half a year now, contemplating what to buy.
Another idea is, what are axle sizes in forks, 9mm,15mm and the other bigger ones. If my bike came with a 9mm QR axle can I buy a 15mm QR axle fork to replace it? will is fit my frame?
Hey Dody , broke my wrist pretty bad last year at antur ... just getting back on the bike but have the fear .. can you recommend a good wrist support/guard ? Cheers fella.
i have a rockshox deluxe shock on my trek. There is a lock out on it but i dont know if it is 2 or 3 steps. when it goes from open to closed i goes all the way, but the other way around there is like another step. It stops in the middel.
is there 2 or 3 steps on the lockout?
#askgmbntech For the shifter script you could also look into thicker chains and internal gearhubs like a nuvinci hub or a shimano nexus/alfine, maybe with a chain tensioner.
yes different types of drivetrain video would be awesome , hub gears anyone????
hey could you still do that video on rebuilding the scout hub? if you’ve already done one could someone link it for me please
With the question about will the derailleur fit on a wide range cassette wolf tooth make a thing called the goat link which allows a medium cage derailleur to fit on a 11 - 42 cassete
On the cassette question. I ran a 25T capacity zee mech with a modified 11-36 cassette to 11-42. Worked well without the need for a goat link or longer b screw. Only think to consider is maybe chain growth so yea. The “No chance” statement is incorrect. It s worth trying.
I live in the dry desert. With of course alot of sand. In order to get all the grit out of my chain. I need to degrease it,clean it and relube after every ride. Is this overkill or good practice for preserving my drivetrain.
very useful advice, having a fatter tyre at front. Thanks
Hey Doddy,
So I just swapped my bikes in 2017 3 times and in 2018 now 2 times. I’m still young and just want to try out different bikes, to get a feel, which bike fits me the best. Do you think that this is a good way of searching my dream bike or not?
Hay doddy, I've seen a trek fuel ex8 26"wheel bike, for a bargain. I'm taking the plunge from road to mtb. What are your thoughts, it has odd shifters? Anything else I need to know?
Edward straka I started out on a Trek stache 5, and I absolutely love it. I think starting out on a solid hard tail is a great way to set a solid foundation for your skills. A full squish bike allows you to get sloppy on the trails, whereas on a hard tail you have to pay closer attention to what you are doing. They are a hell of a lot of fun and just as capable as a full squish just a little rougher ride.
I bought a Giant XTC 26+ with a 2.8 inch (71 mm) wide tire but as I ride mostly on tarmac I want to switch to a tire that has a street profile. What is the widest street tire? I found as the widest only 2.5 inch wide tires like Maxxis Hookworm. Aren't there any wider tires for streets?
My 2018 Spectral 6.0 came with DHF 2.6 front and Rekon 2.6 , rear has a tube now and I just got an EXCELLENT deal on Conti Trail King 2.4 but I haven't installed them yet, good idea? 2019 Spectral comes with 2.4
Love the seagull at 14:37 :')
my dropper post takes two presses to get it fully extended. the first to get 90/95% of the way up the second to get the last little bit. i've tried adding pressure but this didn't change much. any ideas? for reference its a cube dropper that came with the bike when new. cheers
vonpupees Probably cable tension. When you reset the lever, you get your tension back.
If I have a bike with a Fox 34 Float Factory fork (120mm travel) with a head tube angle of 67.2, how would the head tube angle change if I changed to a Fox 32 fork (100mm travel)? Trying to turn a trail bike into a XC race bike.
MI-XC you want to measure the length of the head tube to the floor and then take away 20mm. If rhe Head angle changes by over 10% then don't do it.
I have a trek remedy 7 2018. Would a 2.4 dhr In the rear and 2.5 dhf in the front work?
I have a 10mm clearance both sides in the rear whell im planning to go 27.5x2.25 tires does it still fit to my frame ?
#askgmbntech Hi, I have a problem with mi rear brake. It doesn't brake and it makes a lot of noise. It is contaminated with grease but I don't know form where it comes I have cleaned the bike and changed the pads but nothing. What's happening?
Hey doddy, I too am a big fan of long slack geometry, being a huge fan of pole, Nicolai and my favourite mondraker🤙🏼 I’m currently riding a 2016 Santa Cruz Bronson C(the pink one😉). It’s the best bike I’ve ever ridden, I do a lot of trail riding, but also street riding on it, Fabio Wilmer style, just not as good. I really want the mondraker dune RR, but with 170mm up front, and long slack geometry, I’d be afraid I couldn’t do street riding on it? Should I just get the thought out of my head and stick with the Bronson? Or could I street ride the slack mondy? Cheers GMBN Tech
I got a 27.5 moutain bike frame but the tyres rub on back they are 2.25 was wondering if I could put 2.10 instead
Hey Doddy, I currently have stock Maxxis Ikons 2.2 in y new Giant Anthem Pro 29er, but would like to replace the front with a Maxxis Ardent 2.35. Would it fit in the Fox 32 fork? Thanks mate.
I just got a Niner jet 9 RDO , I’m coming from a 26” and I wanted a 27.5 bike (I’m not a fan of any 29er I have ever ridden) and not sure if you know but the jet 9 rdo is 27.5 plus bike (that can fit 29” wheels) and it comes with 2.8 27.5plus tires on it, my tires being worn out I’m throwing a set of 2.6 DHR 2s on it, I wanted to know if there would be any adverse effects on throwing smaller 27.5 tires on a dedicated 27.5 plus bike that is capable of 29er wheels ?
I'm wanting to start riding and need new tires. Is there any issues if I run 26x2.25 rear and a 26x2.40 on the front? Unsure my 2012 giant boulder can run 2.4 rear. Thanks.
hi ,
i have a 2021 giant stance 2 with 2.3 tiers .i upgrade the front to a 2.5 and the rear to 2.4 ,is it a good upgrade?
Great vid, but I'm still a little confused. can a 52 - 622 tyre replace a 57 - 622 one?
Cheers!
Hi GMBN,
I am quite a newbie with MTB... I recently bought a Rockrider st100. Could you please advise what could be the best upgrade I can make on this bike ? And if you don't mind, an approximate budget I can spend on that... Thanks.
what tire size should i put in my 27.5 rims 32mm wide (outer) & 27mm (inner) to fit my 26er frame in the rear?
Is a 27.5 plus better on my xc 29 Er . I can use either on my xc Scott Spark with my 148 /110. Hubs
It seems very difficult to understand what rim width and what tire width will equal actual tire width in the end. With each rim and tire manufacturer having so many different standards. Is the only way to know what the end tire width will be is to actually mount the tire and the rim and then measure? For instance, I am curious about running a Light-Bicycle 30mm internal width rim with a 48mm Switchback Hill tire. However, my frame will accommodate 52mm maximum clearance. Will this rim and tire combination equal out to over 52mm? Is there any way I could figure this out before actually buying the rims and tires? Thanks
My name is Jeff I do fix place on the side and getting back into mountain biking and every type of writing you think of but my question is was the big difference between the hybrid bike with a 700 C rooms and tire to mounting bike like 29 or a 27.5 mountain bike because I am converting a hybrid bike from Academy Sports to a mountain bike with 29 rims and tires instead of the 700c and changing some parts from breaking your combo to a separate braking system like a hydraulic brakes and separate gears from. 8 gears to maybe 10 or 12 gears. 800 millimeter bars with or 45 stem
Doddy, I wanna know does J-Bended spokes have barely any difference in performance, durability and stiffness when compared to straightpull spokes?
Hi Doddy, I love how you pull stuff off Blake’s bike when he’s not about. Suggest stripping his bike like an exploded drawing and misting his parts with pink metalic fleck.😁-kidding!
Top bloke!!!
Should the rear tires be smaller than the front tires? I running 27.5 x 2.6 (continental trail king) for front tires now.
please answer my question
#ASKGMBNTECH I love riding hardtails on every kind of trail imaginable. Because the rear tire is going to take harder hits than a full sus bike is it better to run heavier carcass tires even on flat trails? What would the downside be as far as weight? How much would a thicker tire effect pedaling during climbs and or long flat sections? Would higher air pressures create noticably less rolling resistance? Or should I settle for running a fast and lighter tire on more rough trails?
Hi need help i had purchased a fat bike 26*4 inch
Can i use a smaller size tyre in same 26 inch frame or any solution to my problem its too heavy to drive
I am running a 1x11 Shimano XT setup with a RaceFace narrow wide chain ring. I have noticed I must have caught my derailleur at some point as the paint is scuffed off the metal frame over the lower jockey wheel. It is now not changing gear very smoothly so I thought the rear hanger or mech is bent, looking at the chain line it appears to be perfectly straight. How can I tell if things are bent, is there a way to use a ruler or a straight edge to measure things or should I be looking at other things like replacing the gear cable (had it on for over a year now). No matter how many times I try to index my gears I can hear a slight clicking in certain gears and it jumps occasionally.
Thanks Doddy, loving the new tech channel!
ultiss checked all that and all good.
Hey i have a roscoe trek 7 and i changed the tyre on them to a 2.4 and the bike is more so down Hill so is that a good size
