Hey crew. Hoping for reports of experience, not 'I think it will/won't work'
Brief: Needing new 170mm boost shimano XT cranks for Felix's new build.
He'll be running 11sp shimano drivetrain. Partly coz I have new spares, partly to save money, partly because i'm not sold on 12sp, partly because Felix doesn't need the range, mostly because of the absolute reliability he's got out of 11sp XT.
I can't get boost 170 M8000 cranks anywhere on line. 175 yes, 170 non boost, yes. I know I can run non boost M8000 with boost frame, as his current bike has for the last 18 months, but I'd prefer boost cranks on the build.
I love DM cranks, so the new M8100 cranks look like a great option, but everything I read says that shimano have changed profile of their ring and chain that aren't cross compatible with other brands or 11sp chains. @The Duckmeister confirms that it 'can' work with an 11sp chain, but its a bit rough, so not wanting to go there.
@Boom King is checking on whether the Bergtech 12sp ring for shimano DM cranks will work with 11sp chain. Not sure yet.
The easiest option IF it works, is M8100 12sp cranks/ring/chain IF it works with an 11sp derailleur and cassette. I can't see why it won't...but there's a lot of things I can't see until it's too late.
Am I missing options? Just to confirm, I prefer to stay with shimano cranks. @russthedog has suggested that the Revel runs the cranks pretty close to the frame, and to be aware that chainring bolts on m8000 stick out a bit more than a DM ring, and to be aware of that, so the 12sp DM cranks/ring/chain is the go if it works on 11sp cassette and derailleur.
Any expertise welcomed before I lose my mind. Cheers.
