E*Thirteen Helix R Cassette


The e*thirteen HELIX R 12 speed cassette is the perfect match to our 1×12 Wide Upgrade Kit. The HELIX’s 9t sprocket gives it 556% range – more than SRAM™ options (500% or 520%) and at a lighter weight.

Price is for full cassette including steel cluster and aluminium sprockets.
