GOLDIX SL CNC Road Bike 12-Speed Cassette Ultralight Freewheel

GOLDIX SL CNC Road Cassette Precision Engineering and Lightweight Construction

Precision CNC machining produces perfectly aligned teeth that eliminate the tolerance stack-up common in stamped alternatives, ensuring crisp shifts under load on every gear transition. The ultralight freewheel design sheds grams without compromising durability, a critical advantage during long climbs or sprint finishes where rotational mass directly impacts power transfer. Available sprocket sizes range from 11T to 34T, giving you the flexibility to choose ratios that match your terrain and fitness level. Material composition uses hardened aluminum alloy with selective nickel plating on high-wear surfaces, extending service life across thousands of shifting cycles. Whether you ride road, gravel, or mixed-surface routes, this 12-speed cassette integrates seamlessly with Shimano and SRAM derailleur systems rated for 12-speed chains.
