E*Thirteen just expanded their line of beautifully machined cassettes to include the new Helix Race series, featuring two new cassettes with unique gear spacing. The E*Thirteen Helix Race cassettes come in two variations: the Helix Race 12-Speed 9-52T Cassette and the Helix Race 12-Speed 13-52T Cassette. Both cassettes are compatible with XD and XDR free hubs only, are made from 2 aluminum and 10 steel cogs, and are cross-compatibile with Shimano, SRAM, and TRP drivetrains and chains. They have replaceable aluminum and steel clusters, and are offered in five bright anodized colors or a PVD finish for improved durability and wear life. Find specs on each below.

E*Thirteen Helix Race 12-Speed 13-52T Cassette

Originally designed for e-bikes, the 13-52T cassette narrows the ratio percentages between gear shifts and pushes the gearing lower for a propensity toward low-speed climbing—or loaded bikepacking, perhaps.
