Fat bikes are gaining popularity and larger component makers are starting to take note. Many fat bikes have 100mm-wide bottom bracket shells. This width is necessary to clear their voluminous 3.8in to 4.7in tires. SRAM’s two fat bike-compatible cranksets come in at the X9 and X5 levels.

Unlike SRAM’s other 2×10 cranksets, which have a 120/80mm bolt circle diameter, these two new models will have a smaller 104mm bolt circle diameter to accompany their lower 36/22-tooth gearing. Both the X9 and X5 models will be available in 170mm and 175mm crankarm lengths.

Price for the X9 crankset is $314, while the X5 version will retail for $169. Both cranksets come with SRAM’s GXP bottom bracket.
