E*Thirteen Helix R 3-Bolt Direct Mount Chainring

With an E Thirteen Helix cassette and a SRAM crank, you can now run Helix SRAM direct mount rings. Designed to function equally well with SRAM and Shimano chains, this ring brings insane amounts of CNC detail as well as being offered in anodized colors to match cassettes as a system. Theexclusive 9T cassette is best enjoyed with a 2T smaller front ring to get the full benefit of less chain and more clearance and range for the same gearing at the top and even lower at the bottom.
