Reviews

High-quality cassette that works reliably

"A high-quality cassette that runs quietly. Compatible with the SLX trigger shifter. However, the quality of the spacer rings has declined."

— Kevin O. (4/5)

Reliability and durability

"This is my third one. The only reason to replace it is wear and tear. No broken teeth like you see with other American brands. It’s a bit heavier, sure, but the shifting under load is exceptionally smooth, even with the 2026 Di2 versions. It requires regular maintenance to keep it running at its best."

"The product is as described, but it would be nice if the parts were pre-assembled so we wouldn't have to struggle during assembly trying to find the right position for the spacers—especially for beginners like me, of course!"

XT 8100 Cassette

"The cassette arrived with two damaged teeth on the '51-tooth aluminum rear sprocket.' Probably due to a fall. The cassette wasn’t in its original packaging. That probably explains it. It’s a shame—that’s not very professional for a big company like that. I can’t return it because I’m not home during the week, and on weekends I don’t have much time."

— Vedrenne (1/5)
