Designed and tested in Canada, then forged from 7050 aluminium for superior strength, the Aeffect R crankset offers a rowdy strength-to-weight ratio and the versatility to get after it anywhere on the mountain.

Highlights

• Forged 7050 aluminium arms with an enduro rating at a lighter than expected weight
• Black satin finish that ties the bike together, scratches and all
• 24mm steel CINCH spindle, 137mm long
• 51mm chainline
• 632g (170mm arms, 32T alloy chainring)
• Lifetime Warranty, crashes included

Strong contender

Forging 7050 aluminium gives Aeffect R its strength, earning it an enduro rating without the weight you'd expect, and it comes in a 165mm length for extra clearance as well as 170 and 175mm.

Swap rings with CINCH

Race Face's CINCH system lets you swap chainrings of all shapes and sizes, and is designed to work with your next bike, and the bike after that.

Compatibility & fit

This crank uses Race Face's 24mm CINCH spindle, 137mm long, for a 51mm chainline. Race Face notes its 24mm spindles aren't replaceable, so this is a 137mm-spindle crank for good. You'll need a 24mm bottom bracket that suits your frame. Chainrings and bottom brackets are sold separately. Crank and bottom-bracket fitting is a separate workshop service at Tune Cycles, and we can check your frame's bottom bracket standard and chainline with you before you order.
