This fits a SRAM DUB style BB and it came off a 2012 SHIV that had a BB30 but it should fit any SRAM DUB configuration (check with SRAM first, but that's what they claim to be the benefit of DUB).

The crank arms are 165mm. I ran 172.5 for a long time and then moved to 165mm at the recommendation of a friend who raced a bunch and he was right. 165's didn't really seem to make me faster, but after 112mi (I did triathlon), my legs felt better for the run.

The rings are 2x12 46/33T and this crank has a built in QuarQ D-Zero power meter which also works great.

Everything works great on this setup, I simply don't use it any longer after I retired from triathlon racing and disassembled my race bike.

Feel free to ask any questions before bidding!
