Ethirteen Helix R 9-39T cassette, 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. 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.
