Bringing cutting edge performance to the diverse needs of drop bar off-roaders Reserve’s 40/44 GR gravel wheels are tailored for the demands of off-road exploration and gravel riding but with an aero focus. Leveraging Turbulent Aero technology the 40/44 GR features a 40mm front paired with a 44mm rear establishing it as the fastest and most stable Reserve gravel wheelset to date.
