The GMR 38mm rim depth delivers versatile all-round performance for everyday cycling.
The 38mm height provides genuine aerodynamic advantage over standard alloy wheels without excessive side area that catches crosswinds, making it ideal for variable weather conditions. The shallower profile also keeps weight down, a real benefit on hilly terrain. Optimized for modern wide-tire setups, this tubeless disc-brake wheelset features a 19mm internal width that handles rough road surfaces with confidence. It's engineered for lower tire pressures to reduce rolling resistance and improve compliance. Testing shows fastest speeds across most wind angles with a 28mm tyre, giving you the flexibility to run your preferred width without compromise. A genuine all-rounder that balances aero efficiency, climbing capability, and real-world durability.
