The all-new SD B-85 Crankset offers a full range of crank sizes, from 140mm to 180mm in 5mm increments, all in a durable 2-piece design. Unlike other brands that split their cranks into separate product lines, SD ensures that even the shortest sizes maintain the same strength and reliability as traditional pro-level options—perfect for younger riders tackling bigger jumps.
A standout feature of the B-85 is its innovative chainring installation system. No more dealing with two-piece chainring bolts—the hex bolts screw directly into the crank arms for quick and effortless chainring changes.
Built for performance and durability, the SD B-85 Crankset delivers pro-level strength at an accessible price.
