Cranks come complete with your choice of chainring size, spacers, spindle bolt and aluminum bottom bracket to fit any threaded 68/73mm bottom bracket shell. 49mm chainline, 168mm Q-Factor.
Trailcraft Cycles high performance aluminum cranks feature a direct mount interface with 26, 28, 30, and 32 tooth narrow-wide/drop stop style chainring options. Our new direct mount crank system typically drops 150 grams or more off a traditional stock square tapered setup and allows way more gearing options never before found on 127mm, 140mm, 152mm, and 165mm crank lengths. We love this setup so much it is now a stock option on all of our complete bike configuration builds - and now also to riders who want to make a current bike you own lighter!
This is an incredibly light and stiff high-performance crankset. With 26, 28, 30, and 32 tooth options you can now dial in the perfect gearing for super steep riding terrain. The crank arms are forged and use a BSA (Shimano standard) 24mm spline interface spindle CNC machined from 7050 aluminum alloy. Removable 3-bolt direct mount ring design offers the ability to quickly change different chainrings depending on your next ride location or race.
This is a complete system of crank arms, bottom bracket, and your choice of chainring size. These cranks will work on all standard 68/73mm threaded bottom brackets shells. Additional chainrings may be purchased separately.
FUTURE PROOF! If you want to go bigger than our 32 tooth, our direct mount cranks are compatible with other brands chainrings using the common spline attachment system and 6mm offset spacing (49mm chainline).
