Helix Race 107mm BCD Chainring

CR4HRA-148

GRAVEL HARDER. ADVENTURE FURTHER.

The Helix Race 107 BCD Chainring is a high-value quality upgrade for Gravel and Road Cyclists using 4-bolt 107 BCD cranks such as SRAM® XPLR or Power Meter Cranks like Quarq Force or Rival. Take full advantage of e*thirteen’s widest range cassettes by dropping 2 teeth or more in chainring size with our smaller 38, 40, and 42T sizes. A combo that supports steeper climbs and faster descents.

Helix Race 107 BCD rings are forged from long wearing 7075 alloy and CNC optimized for stiffness, lightweight, and chain retaining performance. Black & grey color options to coordinate with e*thirteen 9-45T and 9-50T cassettes. Like all e*thirteen chainrings, they feature cross compatible tooth profiles, switching seamlessly between SRAM® or Shimano® 11 and 12 speed drivetrains for absolute build freedom. Chainline is determined by SRAM® crank assembly, 45mm for normal width cranks, 47.5mm for wide cranks.
