ZTTO Ultralight CNC Cassette — Wide Ratio
⭐ Club Tested
Put an 11-50T set on my own trail bike to shed some cassette weight — shifts as smooth as the stock one it replaced, easy install onto the existing freehub.
Lighter Climbs, Wider Range
CNC machined 7075 aluminum spider and largest cogs · Steel small cogs · HG freehub compatible · 10/11/12 speed · 11-46T to 11-52T options
⚙️ Hybrid Construction
The largest four cogs are CNC machined from 7075 aluminum, the middle cogs are steel riveted to an aluminum spider, and the smallest four cogs are steel and easily replaceable — a lighter cassette without the XD-only compatibility headache.
🔧 Mass Compatibility
Fits standard 8-12 speed MTB splined HG freehubs — no need to swap your existing wheelset or freehub body.
🌀 Narrow-Wide Tooth Profile
Dedicated tooth design to stop chain drop when back-pedalling and keep shifting clean under load.
🪶 CNC Lockring
Full CNC machined 7075 aluminum lockring rounds out the weight savings.
