RaceFace Aeffect Crankset - 165mm Direct Mount CINCH EXI Spindle

Race Face Aeffect Crankset – 165mm, 24mm EXI Spindle, Black

The Race Face Aeffect Crankset in the 165mm length is engineered for aggressive trail riders seeking a shorter crank arm option for improved clearance, increased cadence efficiency, and enhanced control on technical terrain. Built from forged 6066 aluminum, the Aeffect crank delivers XC-level weight with trail-ready durability. With Race Face’s adaptable CINCH interface, riders can easily run direct mount chainrings or swap to 1x, 2x, or even 3x spider configurations as needed.

The 24mm EXI spindle ensures broad compatibility with Race Face X-Type and Shimano Hollowtech II bottom brackets. Multiple chainline options—made possible by flipping direct mount chainrings or installing CINCH spiders—support both standard and Boost hub spacing. Lightweight, durable, and highly configurable, the Aeffect 165mm crank is an ideal upgrade for modern trail, all-mountain, and aggressive XC setups.
