Review on JFOYH Cassette Mountain Bicycle Freewheel 46T by Ryan Larson

Weighs 382g out of the box compared to 613g for the SRAM NX PG-1230 it replaces. It features a SRAM GX Eagle chain and front derailleur. It doesn't shift as smoothly as an NX cassette, BUT it solved my main problem with derailleur skipping when pedaling backwards with an NX cassette on a 50-tooth gearbox. In fact, I just rode an MTB enduro. Holds up well. We'll see for long-term performance later. I will continue to tweak my GX kit to shift more smoothly. One star is deducted for this reason and because of the higher price than the NX cartridge.
