Hello and thanks for checking out this listing of a new set of 172.5mm Praxis Zayante Carbon crankarms! These crank arms were swapped off a brand new build in favor of an alternate length at the time of sale and will come to you in the mint “take-off” condition. They will come to you in the new “take-off” condition seen in the included photographs. This crank is compatible with nearly any frame’s bottom bracket configuration assuming the correct parts/adapters/spacers are used thanks to its stepped M30 spindle. Designed for 11-speed drivetrains. Includes what is seen in the photographs. Please see the included pics of the actual crankset you will receive. Please contact me with any questions, I will do my best to answer them.
