e*thirteen Helix R Cassettes
Vital Review
Overall Review
E*thirteen jumped into the cassette game a few years ago, looking to disrupt the market with a unique take on how to eke out wider range from a 1x drivetrain. We’ve had good results with their two-piece cassettes to date, although we did note that shifting could sometimes be a little bit “clunkier” than with original SRAM or Shimano cassettes.

Overall Review
For the last year some friends and I have been toying with the idea of riding the Colorado Trail from Molas Pass to Durango – a ride actually deserving of the word "epic." Three weeks ago we made the high-country adventure happen. We planned to tackle the beast over two days with a sag-wagon full of friends and post-ride libations to meet us in the middle. The day before we began everyone was busy ensuring their rides were ready for the challenge. "Did you swap out that 34-tooth ring?" "Damn straight, I'll take every advantage I can get!" replied my buddy, Nate Work, who, just days earlier...
