Link to the plastic ones? Who makes the plastic versions your measuring?

CeramicSpeed ~500eur for a wheelset bearings.... for ... .5 ? 1W difference? if any ... ?

Only worth it for corrosion resistance. Standard bearings can be made to spin just as freely. People may also get ceramic bearings then overtighten the preload! 🙄

So one thing I’m curious about is why in the heck do they still sell the SL7 and not the SL8 with 105di2/105mech.

For BB, just go for good quality steel, since most of our cadence spin wont be over 100 or 1000 , some-more steel bearing long lasting than ceramic bearing. For wheelset , i believe the difference for ceramic bearing will be during downhill only have the difference speed compare with steel bearing.

out of my 8 years of "serious cycling", the only bearing that failed me is ceramic bearing, it was BSA dub BB. A day after riding in the rain, that ceramic bearing couldn't rotate at all, because the steel race rusted, and the rust stopped ceramic balls from moving.

Ceramic bearing is like 10 times the price of steel bearing. So to change 1 set of ceramic bearing, i can change 10 times of steel bearing. which one will last longer? Of course, i have to do the changing myself and not send to workshop. i once had a bike that always trap water at the bb area and i had a set of ceramic bearing on the bb. the bearing was ok, but the raise was fully rusted and need replacing. So money wasted. Until one day they can come up with a ceramic bearing with ceramic raise that is 100% rust proof, im buying steel bearing instead.

I'll tell you when I very clearly sensed the impact of ceramic bearings in my wheels. More than a year ago I bought a pair of Swiss Side Hadron Ultimate 625 wheels that come with DT Swiss' 185 hubs that contain ceramic bearings. It happened repeatedly that downhill - when I was rolling together with other riders, same rider position, similar road bikes - my bike started rolling perceptibly faster than their bike. I repeat: this did happen at multiple occasions. For me this was convincing enough to plan for next spring the swapping out of bearings in my BB and pulley wheels for quality ceramic bearings.

what happen with ceramic bottom bracket is made metal part turn into magnetic metal. till today i not know what make it into magnet probably friction from the ceramic ball but for sure i do not know

Can't go wrong with SKF or NTN quality steel bearings

Ceramic are pretty expensive for the gains , in my experience they haven't lasted as long , put Ceramic in my mountain bike wheels , as they needed replacing not to make me faster 🤣 rear bearings were dead in 6months grumbling nicely

The guy from the SEKA brand trying to BS us into believing that design of the seat tube and drop stays junction actually serves some purpose. That kind of marketing really pisses me off. I'm really starting to get annoyed by the industry and the lying.

I lose about 5psi after a week. I come from riding latex inner tubes so the 5 lb lost isn’t a big deal. People make it big deal about checking their air pressure before each ride. It’s just part of the game

Handlebar are the last part i would take a bet on (with forks). Nowaday there are chinese builder with a reputation for quality like yoeleo or winspace or exs for handlebars but those are far from cheap. If i had to take a bet on something cheaper i would prefer to go for something like Ryet that try to build its name. They know if they mess up they damage their brand. On the other hand a Roval knockoff might help you make you riding buddy envious but if it fails no brand cn be accused of messing up anything.

Height: 178,5 cm ≈ 5'10" Insteam: 83.5 cm ≈ 33" Should I choose S or M?

I love this. Thanks for sharing

what size is your bike, my bike is a 61 and i always worry about boxes fitting my bike. You look like your bike might be a 58

which one would you use for an ironman70.3???

There is rubber cleaners for shoes. Amazon has it. I use it on the ends of my sneakers.

Thank you!! I am trying to get my partner new shoes for Christmas. He's an avid rider like yourself. He's picky. I've been researching like crazy. I know he likes Specialized and Fizek. .

It feels like there is something missing from this review, which is really just - you on the bike doing a ride and showing the operation of the system. You never show the actual refilling action either, you only talked about it. Otherwise very thorough. Thanks

Thanks

what prep did you do to the rotors before swapping pads? Ideally this test should have been performed on a set of new rotors. If the existing rotors had already been used with the Shimano pads, there is no way the AB's were going to perform as well. The Shimano pad material was already embedded into the rotors. So unfortunately, unless these steps were taken, this is not a valid comparison

how well would it work on a road bike with clip-on t bars?

Can't we just have the best of both worlds lol

The chainring looks more like a 66T or 68T one. 😮 My 60T one (Triathlon) looks much smaller. Maybe 'cause of different framesize. 🤔

What stem is on your bike

Specialized missed on the head tube: too short. Most Aethos riders use a bunch of spacers.

I see that Rapha is still terrible in its design of the front chamois. It still looks weird (I always had to "casually" hold my helmet or something else in front of me when walking around, because of how bizarre it looked.) and is, no doubt, still damagingly uncomfortable for a man. This is a shame because the padding they have for the sit bones is unparalleled. My Rapha shorts were also shockingly non-durable.

I want to see a head to head comparison between the 2024 aeroad cfr vs the trek madone SLR gen7....an aero bike showdown

Great video with a great breakdown of the event. I hope to do the 312 in the future.

clown: how can you not know whether 2000 or 2500km?????

Do not risk ! I didn’t and they failed !

I had a defect, 1 of 4 wouldn’t inflate. Or more like very restricted airflow.

“Nearly 30 in two months…” laughs in 50s tones

Shoe covers is probably a few watts. Also heard water bottle in your front jersey is a few. Great vid.

Wider, more comfortable, tyres actually brought me back to cycling. Riding 23mm tyres at 120 psi killed all the joy.

Repeat after me - "BYOO-TIL"

Pro tip, grab a magnet and see if it adheres to the largest sprocket (which does have ramps machined into it) Aluminium isn't magnetic, so that's the easiest way to check if it's steel or aluminium. (Probably won't be titanium anyway)

Found this video a little later. Wanted to buy a Endurace cf slx 8, and i'm 170cm/81? XS?

Hey!! Excellent video, I’m thinking of buying it, but if I decide to travel with my MTB, can it also be used? I would like to buy one that works for both

Thank you i have a broken clavicle and i did sergury 2 weeks ago, video was so good for me💙

Just got mine installed. The reasons? 1. Arthritis in the hands, 2. Fits well on vintage bikes, 3. Price, 4. Don't have to buy another crankset, cassette, brakes, etc. Works well.

What tool your were using to mount the tire back on the wheels?

Can someone give me real frame weights for the blue frame?

How tall is the rider ? What size bike did they use? Please and thank you

Doing a good job for the summary. I would add the bottom bracket. Going from 3 to 1 has created a new market dimension. Also rim to disc brakes was non existant few years ago and they are much better for me going down the hills in Spain.

Can't stand those ones that live in the past... move on... 🤣
