The all-new SD B-85 Crankset is designed to meet the needs of riders of all levels, offering a full range of crank sizes from 140mm to 180mm in 5mm increments. Its durable 2-piece design ensures that even the shortest sizes maintain the same strength and reliability as traditional pro-level options—making it an excellent choice for younger riders tackling bigger jumps. Unlike other brands that split their cranks into separate product lines, SD provides consistent quality across all sizes.
Innovative Chainring Installation
One of the standout features of the B-85 is its innovative chainring installation system. Say goodbye to the hassle of two-piece chainring bolts—hex bolts screw directly into the crank arms, making chainring changes quick and effortless.
Built for Performance
Engineered for performance and durability, the SD B-85 Crankset offers pro-level strength at an accessible price.
