Cassetta ethirteen Helix R, unlike SRAM Eagle, the Helix R cassettes have replaceable gear groups. This means that ongoing maintenance and replacement costs will be less than half of those of SRAM cassettes. As an additional bonus, the Helix R 12s clusters are backward compatible and can be used to upgrade the existing TRS+ 9-50 cassette. When installing the Helix R cassette, as with any cassette, it is advisable to check the wear of the chain. If your chain shows a wear of 0.5% or more, you will significantly reduce the lifespan of your new cassette. Installing a new chain with your new cluster is a much better and more economical solution.
