Thank you! My 2022 Shimano slx freehub that came on my Specialized Turbo Levo Comp mtb failed at around 2,000 miles. I purchased the bike in Nov 2021 and at the time it had all Shimano components. It just started grinding and ate the metal gears. I had it replaced. Luckily I had bought a spare free hub when the bike was new, as during Covid it was impossible to find one. Specialized switched to Shram in January 2022 for their components. Now I know why.

thanks for sharing the part number on the black spacer. My spacer on my XT hub failed today (white spacer). I'm in the United States and shimano USA has no stock available. I ordered a couple of them from the EU and paid a lot for shipping. Still much cheaper than a new hub. This is the hub's last chance. Next step is a rebuild with a DT Swiss 350.

I am a bit confused... Is this a problem with all Microspline hubs (e.g. DT Swiss 350/240 etc) or just the Shimano hubs? Thanks. PS Would be a bit of a problem for the road if the future road cassettes switch to Microspline from HG11...
@ZavyalovCycling

Just the Shimano ones. SLX, XT, and XTR of 2019 gen. Microspline toothing is not a problem. The problem comes from freewheel arrangement inside these hubs. Even Shimano produces some Microspline models now without this problem.

How about this crazy idea. If one has creaking XT hub with worn out teeth… If we use strong glue to merge freehub body into the hub? Then there’s nothing moving, thus no creaking. Then just ride and when bearings get worn out, ditch the whole thing.

I have the Shimano M8120 wheelset. I only ride trails and the creak started at about 40 hours. Replaced the yellow spacer with black one, and put special grease on it. After 20 hours it's creaking again. The bike is still in warranty, but I don't have time to waste. I'm buying the 410 ou 510 hub and try to relace with the same spokes. Plan B is DT Swiss 370, which is VERY expensive in my country.

The 410 has the exact dimensions as the xt so that should be possible to reuse spokes. Saw a reddit thread where a mechanic said he removed all the individual teeth from the spacer but still used the remaining ring. Claimed it stopped creaking but was slightly louder. Im facing same problem.

Thanks for this explanation! My new Giant MTB came with SLX components and started creaking within weeks of purchase, I had to take it back to the shop several times before they finally relented and replaced the hub. After another six months, it's started again and I notice the bike is 'ghost pedalling' when you push it forward, deja-vous all over again. From your experience it sounds as if the only true solution is to replace the hub with something other than Shimano.
@ZavyalovCycling
Жыл бұрын
Welcome! The ghost pedaling itself is not yet a sign of a failed free hub. But you are right with the conclusion - this SLX is likely to creak again and again. An easy and relatively cheap replacement could be Shimano FH-MT510 or 410. 510 shares almost the same shell with your SLX. Meaning you can even get away with your old spokes. 410's shell is a tiny bit different, but it seems the old spokes would suit fine as well. Both 410 and 510 have a pawl ratchet system without all these nasty plastic spacers. However, you might be hating Shimano already and prefer something different like Hope or DT Swiss. It's the best solution, but it'll be 4-5 more expensive in comparison to 410/510. Good luck anyway! 🤘

@@ZavyalovCyclingI have a brand new, unused XT M8110-B. I’m planning to to following: - Remove legs from plastic spacer, so they won’t eat connecting teeth. This way all the teeth connect same time, and thus pressure is more even. I believe that plastic spacer legs actually eat the teeth. They make grooves on teeth. So, cut em off. - Use Shimano Premium Grease on teeth. Maybe I should do a video about this project. 🤔 We’ll see how far I manage to go.

If there is some trick to keep the rear hub bearings in the 240s from getting crunchy I would love to know it. Enduro Parks and downhill seem to really speed them on their way to their death, whereas the XTR, those things can take a beating, still smooth

I have put about 2,000 mi on the most recent XTR hubs. Still going fine. A lot of that downhill and enduro. I have yet to have the freehub problem but it seems like by design it will happen eventually. You kind of wonder why Shimano gave this the green light or did not use something more durable like aluminum rather than a plastic spacer. The previous XTR hub, the last HG driver was an absolute tank just like all the other XTR hubs. I noticed when I picked up this new version they did feel lighter but also not quite as durable. I'm happy the bearings are still decent which is something that I blow up routinely on cartridge bearing hubs. I also learned long ago never to use lower tier Shimano hubs. If it does not say XTR or dura Ace, use something else. I guess time will tell how long this set that I have will go
@ZavyalovCycling

First of all, Happy New Year! Let your XTR hub miraculously stay away from all this mess. My road bike has Dura Ace drivetrain (not the hubs though), and after 20+ thousand miles I have zero complaints. What is more, HG901-11 "dura ace" chain is the most durable chain I've tried. Unfortunately, this kind of experience of a single person does not say much. You might have heard about a recent recall of up to a million of road cranks including lots of Dura Ace ones. The problem has been finally admitted by Shimano after 10 years of complaints. Without a doubt, Shimano has made lots of truly reliable stuff through the decades. But do top tier Shimano lines of today guarantee anything special in comparison to lower tiers? Absolutely not! 😉

@@ZavyalovCycling that is a very solid point, the bonding issue on the epoxy used on many of those cranks. Then the hub issue you bring up. I hope Shimano addresses the hub problem. Their previous hubs have all been pretty reliable. The lower ones obviously not going as many miles or being as smooth but still they did their job. The cranks that looks like or at least they claim to have fixed from this point forward. The part I always found suspicious is they said ultegra and dura ace but xtr 9100 and 9120 / 9130 also use a bonded crank. There was no mention on what was different that I could find
