Here in Brazil, all shimano scylence technology hubs (m7100/8100/9100) fail with a few kilometers of use. The hubs show a horrible creaking noise. The warranty changes but the new hub turn to presenting the creaking noise. A few mechanics who disassembled this hub recommended lubricate the hubs, but the problem continue. I think that shimano mt400 series (with ball bearings) was releases because the problem with this scylence hubs. Great video!!! Thanks!!!!

I tried to get these ended up with 29 race face next 31s so Im happy.

I have stopped mid ride and come home multiple times because of creaking somewhere on my bike. I actually like the cone and cup design as it's easier to overhaul when that time eventually comes, but the overall weight and hub issues are a deal breaker for me. Good to see you thinking outside of the box and giving them a try though!

I have that same noise with my Bontrager wheels, not with coasting, but while pedaling hard in the highest gear. I have just learned to ignore that noise.

Every company has at least 1 bad product. Shimano has creaking hub 👍🏻

Lets go. Most waited of the week

I'm on these right now and have been for over a year. Let's point out that these cost $500CAD and Shimano's goal with this new gen wheel series was to get people using their 12 speed drivetrain, and not top spec performance. They sell them at very low margins. There are surely better wheels out there - but solid performance for that price, maybe not.

Awesome review man! I've got the Shimano m620 wheels, which are pretty similar. They are rocking the trails

I used an XT wheels before but the older one the M8000 one. I was using it for good 2 years before selling my bike and I didn't have any problem with it. The only noise I'm hearing is me breathing so hard from those uphill climb. I do prefer the silent hub too. The engagement for the M8000 wheels was awesome so as the rolling speed. In as much I love the XT wheels, I do not regret selling the bike because I just bought 2022 Santa Cruz Bronson MX which is a totally different bike but oh men I love Bronson. It felt like I was still using my XC bike on the climb. But anyway awesome Video!

I only really care about the weight and ride quality. How are they in that regard? But generally I trust anything Shimano makes since they try to perfect anything they produce rather than focusing on the "next fad".

Re. the creaking sound.Make sure your thru-axle is greased and tightened to the proper torque spec. I found this to be true on my Timberjack that if the rear axle isn’t torqued to spec it creaks.

Always on top level when it comes to rewiews, describing parts . Great video . Greetings from Germany. Cheers

You really do the best reviews. Very informative. Thanks

I split a freehub in the xt set I had and had no end of issues with the toothed plastic ring on the xtr set I had, shop paid me out on the xt's (they'd returned several sets from other customers already) and I I sold the xtr hubs. Those shimano hubs are the worst bike purchase I've even made, they made me hate riding my bike 0/10 would not recommend

Wow love how in-depth this review is, very informative. I got the same wheelset from my work and was curious why the hub was so quiet. I had the same creaking noise and it drove me wild. Some grease and I think it's fixed. Now if I can only find a microspline cassette lock ring and I can take em on the trail.

Wow I'm subscribing to your channel very informative, specially explaining to us viewers on the technology behind it and the specs :)

sadly I had to throw my XT m8100 rear hub. the first thing that broke was the plastic spacer with the small teeth. then as I was going down a mountain it turned into a fixed gear hub. they don't make the XT like they used to.

Muy buen vídeo y bien explicado con todo tipo de detalle cómo siempre, eres un crack.. a mi particularmente no me gustaría que sonarán mis bujes al rodar con unas Ruedas nuevas. Un Saludo 🤙

I would never buy M7100/M8100/(12sp. XTR probably similar issue) - I warrantied the hub once as it started creaking and upon inspection I discovered that the plastic spacer legs were all but broken. Sent the whole laced wheel for warranty, came back with new spacer and grease on it this time - worked better (fully silent coasting, even low speed), but soon it started creaking more and more, and then it chewed up all the spacer legs and locked out the freewheeling mechanism on the trail... Fortunately it managed to chew these plastic pieces completely and clean up the space inside the ratcheting mechanism, and I managed to come back home. The engineering design of the freewheeling mechanism is very good - better than DT Star Ratchet or Chris King IMHO (much larger ratchet diameter, much higher engagement force and with the potential to be lighter than even DT Star Ratchet EXP as all parts are from alu alloy), but the solution with the plastic spacer to eat up tolerance and prevent alu/alu contact likely combined with some slop tolerances elsewhere/axle not being stiff enough etc. leads to very quick failure when used frequently with high torque, as most MTBs are. It is really sad as without this issue it would be an excellent and not too expensive hub (though most people would likely prefer to have the drive bearings be cartridge-style as well for convenience and peace of mind, even if they would need to be replaced and properly serviced C&C hub of this class can last very, very long provided no contamination).

I love the look of those decals, but man that's a heavy wheelset. I just got some 27id carbon rims built on DT240s and they're 1288g... Shame they sent me 29ers when I ordered 27.5 but that's what PayPal disputes are for 🙃

awesome mate ,ive got same wheels 2nd year and they are super nice

I'm hearing hints that freehub noise can be controlled by the right lubrication. aa simple example wold be oil verses grease. but DT Swiss are very specific: use their grease or expect issues. the lubricant and counter spring are in balance. The lubricant lets the parts move smoothly but also cushions the parts reducing noise, ware & impact stress

Cup and cone still..had them 25yrs ago. What happened to new technology, these went out with the Romans. As soon as the bearing race is worn out you are knackered. Doesnt matter how many bearing changes you do 🥲🥲

Great as always

My xt hubs had that buzzing noise out of the box.. it didn't bother me at all.. except for the first time i'd mistaken it for rotor rub since it was almost very subtle. 5 months of use and now it's just completely silent.... I only hear the hubs when im in the workshop doing some maintenance.

Dollar for dollar. The xt hubs are one of the best on the market. The rear freehub functions very similar to a chris king hub

Hello!!! I have no experience with this new generation of Shimano wheels. But with the old ones... my God...

Sunt mare mare fan dt swiss - orice cu ratche (de la 350 in sus) dar nu suport zgomotul de la 54 dinti. N-am avut idee de hub-urile astea pana acum. Multumesc ! Am sa vad de unde pot incerca si eu sa vad cum e. Ai grija !

Hi! I am in Korea, but the information in your video is very advanced. My hand unknowingly pressed the subscribe button. Until recently I rode a 2008 trek8500. I'm on a scott scale 940 now. I am surprised that it is much heavier than my 14 year old bike and I want to change the wheelset and tires. If I buy the M8100 wheel, can I replace it right away?

No spoke holes! Someone had fun building them.

Got the same set few weeks ago. Already dented rear rim. Well, lets see how i get a new one as online hard to get.

Going on second season with these wheels but 29er. Had rear hub creaking almost immediately. Took apart and lubed and creaking hasn’t returned but does make hub louder like you mentioned. Have recently had issue with spokes breaking on rear wheel for no apparent reason. Took to my local mechanic (over 20yrs experience) and he said the bend in the spokes from being machine built was terrible and probably causing the breaks. Also are sure it has rim tape? 99% sure these are UST style which would explain the drain holes wouldn’t it?

Now i know, why i can’t figure out that annoying creaking sound. Replaced and greased bb shell but still had the freaking noise..

A little of silicon spray on the raclet and the are silent again for about 2k.

The Shimano microspline hubs are dangerous garbage. The freehubs lockup. Happened to me and also a friend. They are quick with the warranty but not worth the risk. Imagine having the freehub lock up in a dangerous spot. Switched to dt350 and haven't had an issue since with the hubs.

Does the SLX have steel Splines compared to the XT? Thanks

I heard Shimano gave up selling Scylence hubs because of the technical issues. So Shimano doesn't put "Scylence" label on any their hubs. Thus, I think the coasting noise isn't an issue at all. www.pinkbike.com/news/shimanos-new-xtr-drivetrain-still-isnt-available.html

Hey! Have you tried the shimano MT500 wheels? 🙂

Hope to have that kind of mtb 🎉

Do you guys have a link on how to fix/maintain these hubs? I mean the creaking sound. It’s driving me crazy.

Почему не поставить механизм как в Shimano Silent clutch?

i bought the same wheels 2 weeks ago 😃 the first thing i did,... was to grease the micro spline 😆 on the other bike the creak was horrible, had to grease it after 500km...

I'd like to sete some Chinese carbon 29er wheels tested.. Some that are sub 1400 grams from Speedsafe. I have a friend that has the 1220 gram set and races on them.

ill watch it again later after my duty

Hello.Can you recommend any other hubs with microspline?Thanks

Ugh. I'm about to pull the trigger on a new bike build, and am thinking about getting these wheels instead of a set of DT Swiss 1900s. I read that these lower end DT Swiss hubs take a while to engage. And Shimano XT kit has always worked well for me. Given the comments (creaking, chucking a hub), would Mr MTB advise going with the DT Swiss 1900 wheels? Sticking with XT? Or something else entirely? Any insight would be most welcome!

Cup n Cone bearings are a complete fail as an upgrade. It seems Shimano is trying to grab the stock rim market on mtb’s. Step up to precision bearings Shimano!🙏🔑✌️

I got CR-MO eccentric. Purely awesome.

I would not use the rear hub, creaking will eventually turn into the ratchet mechanism locking and becoming a fixie. Multiple cases of it here if you want all the details. www.mtbr.com/threads/multiple-xt-m8100-hub-failures.1139315/

Where can I buy shimano wheels but with a 135mm QR axle?

How do you stop this sound! Mine is doing it I tried removing old grease and putting fresh stuff in there and it was good for about 3 runs then back to inconsistent sounds… and and it driving me crazy!

can you pull the freebody off without tools? i have a couple of wheels w dt swiss 240 and wont buy another rear wheel that doesnt do this

What brand and model frame

Hi. I’m going to build a rear wheel and trying to decide on a 622x30 rim to buy. Do you think an asymmetrical rim with about a 2 - 3mm offset would work okay with a 142 OLD hub or do offset rims require boost spacing? My plan is to build a 30mm internal width rim using 29x2.4 tires. Thanks.

wow they really stuck with unsealed bearings. that's not very impressive

What is the point of asimetrical rim? Is there a tech reason or just smoke-marketing?

I would not buy shimano freehub again, I am tired of lubing that part over and over again. Luckily I found a thread about this problem instantly when I had it for the first time.

Hi from Brazil, recently o bought slx 7100 brakes and 180/160 rotors RT56, i wanna to ask you if i lose too much braking power for not using slx rotors... thanks! edit: im also using resin ice pads

What is the alternative to these 'silent' hubs for SHIMANO drivetrains?

Can I convert TA 148 to QR 141?

Shimano needs a hud like I 9 hydra

It would sell!

these rims have nipples holes under the rim tape right or are they installed by fishing magnets

whats up with the drainage holes? wont they let water in? thks.

Shimano issues: Too good product at too good price (issue for other brands)

Never again shimano microspin hub. 2000km dead due to crown washer wear - exchange to new fixed washer redesign by shimano does not help.

18mm spanner.... I thought it was 17mm

Don't buy these hubs. Worst Shimano product I've ever bought. Started creaking and howling within a few months use. Wish I had done research before having a wheel built with them. Garbage.

well u buy for riding not for looks

For sure its expensive... so it should not be creeking

My x1900 dtswiss still better :D

Cup and cone? Still?Boooo

Boo no buzz 🐝 sounds

These wheels don't deserve any good press. Unless you like creaky freehubs that eventually explode into a hot janky mess. Shimano Clearly over engineered every part of this mess and I hate dealing with them.

Heavy and over engineered hubs. Reliability is poor too. I love Shimano, but I cannot trust their wheels. Swapped them right away for DTSwiss.

12 speed lol

what a ugly bike kekw
