Brand new from SD, the B-85 Crankset brings a range of crank sizes in a strong 2 piece package from 140mm to 180mm in 5mm increments. Usually to cover a range like this companies split their cranks into two distinct products, but SD has recognised the need for shorter cranks to be as strong as the traditional pro sizes as the kids start to hit bigger and bigger jumps.

A technical innovation, the SD B-85 cranksets have a unique way of installing your chainring. There is no need anymore for two-piece chainring boltsas the hex bolts screw directly into the crank arms for easy installing and changing your chainring.

Performance and strength at a friendly price.
