Strong Contender

Forged 7050 AL gives this crank phenomenal strength, earning it an Enduro rating at a lighter than expected weight and is available in a 165mm length.

Black To The Future

Even if your crankset will inevitably get covered in scratches, dust, and mud, this black satin finish does really tie the ride together nicely.

Consider Yourself Covered

CINCH System is designed to work with your next bike, the bike after that, and the bike after that.

Here Come The Hard Chargers

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

New Cranks

Packaging was great, fit was spot on, and they ride great as well. Quality products.

Great crankset at a great price

I already had these cranks in the 175 length, but wanted to see what shorter cranks (165) would feel like. I already knew the quality would be great, and given the relatively inexpensive price tag, it seemed like a low risk experiment. Upshot: so glad I tried shorter cranks — I highly prefer them.

Excellent Aluminum Crank

I bought this to replace the stock FSA cranks that came on my bike, since the bolt pattern really limited my chainring options. Cinch is great, easy to swap chainrings and have so many options now (currently running oval). The cranks look great, super easy install, and I love that they come in 165mm length for short legs and more clearance.

The Superior Aluminum Crank

This crankset is one of the better ones at this price point, I have ever used. They are very stiff without a hint of flex under load or on big drops. The Cinch setup is awesome. Right now I've got the Shimano 12 speed ring on it but if I ever wanted to use a normal Raceface ring I could. These cranks are easy to install too; it took me all of 10 minutes. I used a Shimano XT bottom bracket too, only because it is like half the price of the Raceface one. I think a race one would be about the same ease of installation as well.
