The SRAM XPLR XG-1251 Cassette is a wide-range cassette built for 1x gravel drivetrains, offering smooth progression for climbing gravel and tighter steps for holding speed on faster terrain. MINI CLUSTER construction combines CNC-machined and pinned cogs, keeping weight down while pairing with XPLR rear derailleurs for consistent shifting on mixed surfaces.
Cogs mount to an XDR driver body and use a nickel chrome finish for wear resistance, with shift ramps tuned for electronic drivetrains. The cassette pairs with Flattop road chains, giving riders a durable, precise-shifting setup for daily gravel rides and longer days away from pavement.
