SRAM Red E1 Aero 48t Direct Mount Chainring
The SRAM RED E1 Aero 48T is a direct-mount chainring built around X-SYNC wide/narrow-tooth technology, which alternates tooth profiles to keep the chain seated under load. Its aerodynamic profile suits time trial and triathlon applications, and the 48-tooth configuration pairs with SRAM RED AXS drivetrains. A laser-etched finish adds surface hardness for extended service life.
Machined from aluminum, the ring resists flex under sustained power output, reducing the risk of chain drop or inefficient pedaling. X-Range gearing compatibility ensures smooth chain progression across a wide cassette range. The direct-mount interface attaches to compatible SRAM cranksets without a separate spider, keeping the assembly compact and reducing overall drivetrain weight.
