Description SRAM Rival Cassette XG-1250 12-speed Tried and tested in the mountain bike sector for years, the 10-tooth sprocket is now also finding its way into racing bikes. This is made possible by the SRAM XDR freewheel standard. The advantages are obvious: with the same bandwidth, the cassette has become even lighter. In addition, weight can be saved on the crank, as smaller chainrings are necessary for the same maximum development as with an 11-tooth sprocket. So that the gear steps remain small without having to forego bandwidth, SRAM has upgraded the Rival cassette to 12-speed . The additional 12th pinion significantly expands the intended use the cassette in combination with the eTap AXS 1-speed group. A nickel-chrome coating ensures quick and quiet switching processes. The individual rizels are connected to one another using high-strength, stainless steel pins. The open design of the full-pin construction enables the cassette to self-clean itself in adverse external conditions.
