SRAM Apex 12 Speed Cassette (PG-1231)

Maximum range, minimum fuss. This 12-speed 11-44T cassette provides 2x range in a 1x package and fits on a traditional 11-speed driver body for broad integration. The smooth cog progression keeps jumps between cogs tightest when it’s time to go fast, with more meaningful gaps for climbing.
