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. Wider than the previous gravel wheels to allow for tires up to 50c tires, the 40/44 GR plays nicely with today's slew of big volume gravel tires and a semi-hooked rim makes tubeless set up easier than ever.Built with DT Swiss HubsDesigned to be your no fuss aero gravel riding and racing wheelsetWider internal width of 27mmTubeless and tube compatibleWide/low front mixed with narrow/tall rear for maximum stability, lowest weight and optimal aerodynamicsInternally reinforced spoke holes to strengthen the area where the rim sees the most force, around the spoke nipple.
