Neutron MK2 Ultra-Lightweight 12-Speed Road Cassette (11-30T)

Big ratios aren’t always necessary—sometimes it’s all about tight gear jumps and featherweight efficiency. Tipping the scales at a blistering ~162g–180g, the Neutron MK2 12-Speed Cassette pairs precision CNC-machined steel cogs with a high-strength 7075 aluminum alloy spider and lockring. Available in striking custom PVD and DLC anodized finishes (including Midnight Purple, Storm Green, and Sakura Pink), it gives your drivetrain maximum performance, seamless power transfer, and unmatched style.
