The new Sram XG-1250 Rival cassette just upgrates the Rival to 12-speed. Tried and tested in the mountain bike sector for years, the 10-tooth sprocket is now also finding its way into road 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. 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.

Features:

• 12 speed cassette
• Nickel-chrome coating ensures quick and quiet switching processes
• Full-pin construction
• XDR technology - The XDR driver body is a universal mounting system for cassettes that incorporate cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring new rear axle standards, cassette tools or hub redesigns. The XDR interface is 1.85mm longer than XD and is designed for road hub applications. XDR driver bodies are compatible with all XD cassettes when the cassette is installed with a 1.85mm spacer.
