Cassette ethirteen Helix R 9-50T 12v clocks, unlike Sram Eagle, the Helix R cassettes have replaceable gear groups. This means that continuous assistance and replacement costs will be less than half of those of the sram boxes. As an additional bonus, Helix R 12S clusters are backwards and can be used to update the existing TRS + 9-50 cassette. When installing the Helix R cassette, as with any cassette, we recommend checking the chain wear. If your chain shows a wear of 0.5% or more, significantly reducing the wear life of your new cassette. The installation of a new chain with your new cluster is a much better and economical solution.
