12-speed MTB chains - The ultimate test!

I have been running Sram Eagle on my bikes from February 2018 and a total of about 20 000km. During this time I have tried, tested, liked and hated both OE Sram / Shimano and third party chains, so this post will be a re-cap of my findings with all those chains. I will include a link in the header of each mini-review to one of my favorite online stores, R2 Bikes in Germany. A short disclaimer before I get into it: The mileages mentioned are verified by Strava, but testing conditions and even bikes have not been consistent. I have ridden these chains as mountain bikers do: In various conditions ranging from dry, warm summer days to below 0 °C winter rides. The chains have been cleaned and lubricated after each ride, but have not had any special treatment such as waxing applied. I will also speak about elongation, which is not correct for a chain, as the chain pins wear and this creates play in the chain and causes a worn chain to appear longer, or elongated, when compared to a

Shimano vs Sram 12-speed chains

Having dominated the 12-speed market for several years, Sram is now faced with a tough competitor from Japan - Shimano. The formerly pro-front derailleur outfit has finally admitted defeat and gone almost fully 1-by for MTB drivetrains. Many people and bike OEMs have been excited to change from the quite frankly overpriced Sram components to Shimano. This means you may have a wheelset from a previous bike with a Sram cassette and your new bike comes with Shimano. How will this work? Construction It’s quite obvious what Shimano mean by Hyperglide+, when you compare the Shimano chain to a “standard” Sram chain. The pictures below tell the whole story, but basically the difference are the inner links, which are longer and heavily chamfered on Shimano. Another major difference is that the XT chain is showing significant blackening and rust spots, where as the finish on an X01 chain of similar age and mileage is still in impecable condition. I will not compare the cheaper alternatives f

Fixing Shimano XT/XTR M8100/M9100 leak from master cylinder end cap

EDIT 29.4.2023: Thanks to Oliver for pointing out that Shimano have now made spare diaphragms and instructions on how to replace them available to the public! https://si.shimano.com/en/dm/MADBR01/replace_diaphram This is a description of how I went about repairing leaking M9100 brake lever. Only attempt at your own risk! I’m running XTR M9100 brakes on my Mondraker F-Podium DC and they come with the BL-M9100 master cylinders / levers. I recently discovered a leak on my rear brake lever where fluid was seeping out of the master cylinder’s black plastic end cap. I got a new lever under warranty, installed and bled it and all was peachy until a few rides in “POP” and the end cap was leaking again! The brake still works as long as the bike is kept right side up so I’ve kept riding. The other night I went to replace the brake pads on my front brake and even took precaution to open the bleed screw on the master cylinder when pushing the caliper pistons in. Mind you, this isn’t something Sh
