JFOYH Cassette Mountain Bicycle Freewheel 46T Review

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…

I was pleasantly surprised at how well it worked on the first ride and performance improves over time. I had the lower stem transmission on my Giant Trance X with a Sram SX 12 speed cassette, derailleur and derailleur. One day the switch just fell apart in 2 parts. So I decided to upgrade the derailleur and shifter on GX 12s, but I couldn't upgrade the cassette without changing the hub. This cartridge solved that problem. Now I have a GX shifter, derailleur and this 11-52t cassette. The…

I went with a 10 speed cassette from 11 to 46 teeth and the first few rides seem fantastic. The main advantage is how light it is. Shifts from 10th to 7th gear are lightning quick and very precise, with little change in cadence. 8th through 10th gears are slower and more clumsy. Seemed like a bummer on the dyno, but on the track it works great because when I have to use the lowest 3 gears I'm already moving so slowly that it doesn't matter if it shifts slower than it does over the high gears…

Of course, a part of me is reluctant to pay $150 for a tape that might be crap. This one is in perfect order. This time ZTTO/Bolany really nailed it, figuring out exactly what a weight sausage wants in an affordable cartridge. The 11 speed 11-52t weighs 400 grams. I'm not kidding. That's 95 grams lighter than some of the last lightweight 11 speed cassettes I've bought here for the same price. Wow. Compare that to something like the Shimano SLX 11-46t, which weighs over 700 grams. That's 2/3…
