Our amazing Direct Mount Cranks 140mm and 152mm are in stock and now comes in 165mm too!
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 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 or race.
This is a complete system of crank arms, bottom bracket, and your choice of chainring. These cranks will work on all standard 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 SRAM interface spline attachment system and GXP 6mm offset spacing (49mm chainline).
