WHEELTOP
Focused on budget wireless electronic shifting upgrade kits. The EDS system delivers ultra-fast rear derailleur response with race/eco dual modes, ergonomic shifters fit for small Asian hands. However, it lacks mature mid-to-high mechanical groupsets, slow & noisy front shifting, higher power consumption under race mode and no clutch damping. Mainly for aftermarket individual bike upgrades, less suitable for mass OEM export.
