The Shimano Deore XT Crank Arms are compatible with the following:
My bike came with Deore 175mm cranks. Wanted to drop to 165. Definitely didn’t need XT-level cranks. It was just literally impossible to find Deore or SLX cranks in 165. Thunder Mountain happened to have XT cranks in 165 and I caught them during Black Friday for 20% off. Why not! They’re smooth and work with the entry-level Shimano BB already in my frame. Thunder Mountaun shipped quickly!
Only complaint is they don’t come with the VERY specific tool needed to tighten the center lock chain ring in place. Caught me off guard and needed to run to a LBS just to get them to tighten the chain ring in place. Make sure you have this tool handy if you’re installing on your own!
Ordered Deore XT 165 cranks. Order was processed and shipped by Thunder Mountain in 2 hours. Unbelievable service and the order was perfect! These guys are awesome!
Love the shorter cranks, you wouldn’t think 5mm would make that much difference but I really like how they perform.
As described. Solid cranks. Wanted to try 165mm.
