The Helix Race 9-45T is e*thirteen's 12-speed gravel cassette, built as a drop-in upgrade for SRAM XPLR 10-44T cassettes with 13% more range for the same shifter and derailleur.

Highlights

  • 500% gear range from a 9-45T spread
  • Drop-in replacement for SRAM XPLR 10-44T cassettes, 13% more range
  • 2 aluminium cogs, 10 steel cogs
  • Grey/Nickel anodised and plated finish
  • XD and XDR freehub compatible

More range on your existing gravel groupset

e*thirteen builds this cassette for SRAM, Shimano and TRP 12-speed gravel groupsets of matching cage capacity, so it drops onto an XD/XDR gravel wheel for a wider range without a new shifter or derailleur.

Compatibility & fit

Mounts on an XD or XDR freehub body (XDR needs the 1.85mm spacer that comes with the hub). Hope-brand XD drivers are slightly undersized and need e*thirteen's cassette shim kit. The Tune workshop can confirm fit and fit the cassette.

e*thirteen covers the Helix Race gravel cassette for 10 years against manufacturing and material defects, plus a discounted crash replacement policy. For warranty support, return the product to Tune Cycles and we'll manage the claim with e*thirteen's Australian distributor. This is in addition to your rights under the Australian Consumer Law. Keep your proof of purchase.
