Fat frames offer more than just squishy tires. The wide BB and chainstays create a stable platform for backcountry shredding. Tangent's fatbike kit is available as a throttle based kit in 100mm BB width at 3kW or 6kW power levels. In order to accommodate the intrusive chainstays on many frames, we've adapted the standard freewheel crankset to accept a 24 tooth 5x74mm BCD sprocket on the inner chainring position (4x104mm BCD is used for the bike driveline). This kit uses the PAS gearset to provide an overall 60:1 reduction with massive torque available at the flick of a wrist. A 6kW variant is available in 100mm width by special order, your frame must accommodate a 32t sprocket at the inner position.
