Flattop wheels

Road/Gravel Flattop chainrings are SRAM AXS drivetrain chainrings that use the Flattop chain profile. These chainrings are designed specifically for road and gravel bikes where smooth chain operation, quietness, and durability are important. The Flattop chain's flat top surface improves chain durability and is well-suited for narrow and precise shifting tolerances. Flattop chainrings include SRAM Red, Force, and Rival E1 models, as well as compatible Wolf Tooth and other accessory solutions. They are not compatible with SRAM Eagle or T-Type drivetrain chains; instead, they require Flattop-standard chains and drivetrains. Choose this category when building or servicing a road, gravel, or road bike with AXS technology.
