Aeffect EXI Crank Arms - Bike Builds

What Our Gearhead® Experts Are Saying:

"I paired these crank arms with the steel Cinch chainring on my enduro bike, and the setup has been rock solid through a full season of rocky descents. The Cinch interface made swapping components simple, and the whole drivetrain still runs quiet."

Somewhere past the trailhead, the singletrack narrows, and the climb gets serious- the kind of ride where every part of the bike either helps or gets in the way. The Aeffect EXI Crank Arms are built for exactly that stretch, giving trail, cross country, and enduro riders a dependable foundation without asking for a premium price.

Paired with a steel Cinch chainring, this setup rewards riders who want a drivetrain that just works, ride after ride. The forged aluminum arms hold their stiffness through hard efforts, while the narrow-wide tooth profile on the chainring keeps the chain locked in through chunky descents and root-strewn climbs alike. It's a combination built for logging miles, not babying components.
