This is a high-spec genuine SRAM XX1 Eagle 10-52T cassette. Paired w/ XX1 Eagle 12-speed chain a noticeable improvement to shifting on my ebike (they tend to be hard on drivetrains). Definitely superior to stock GX components. It was very hard to find - unavailable from local shop and most reputable online bike-specific merchants long lead times etc. Was able to find on Amazon but had to pay a tidy premium above list price to get my hands on it. Nature of the beast these days.

For those that donÔøΩt know at the time of this review there is a huge supply chain issue in acquiring this product SRAM XX1 10-52T. CouldnÔøΩt find anywhere other than Australia and Ukraine and they are priced 50% higher. And then I found here. I was skeptical at first given supply issues but this is the real deal. Upgraded my 42T to this 52T with a lighter technology. Put AXS derailleur and shifter and a new chain. CanÔøΩt say enough how much this has improved my range particularly on the uphill battles. I ride an IBIS Ripley LS and with this addition this bike now rocks. Thank you to the seller who could charge a premium because of supply issues but is not.
