Reserve 40/44 GR R45D

Why We Make It  What even is gravel riding? It runs the gamut from leisurely off-road exploration to speed-focused dirt and single-track riding. This wheel is more the latter than the former, with an aerodynamic profile and low rim weight. It aptly fills the need for a rugged, high-performance wheelset in our product lineup.  Why You Want It  Reserve’s 40|44 GR rims are a 40mm front paired with a 44mm rear, built wide to allow for tires up to 50c. Reserve uses internally reinforced spoke holes to strengthen the area where the rim sees the most force, around the spoke nipple.   We pair the 40|44 rims with our R45D™ Centerlock hubs, powered by our patented RingDrive™ system. You want them because their 45-points of simultaneous engagement deliver instantaneous engagement and superior power transfer. We wrap the system in a lightweight hub body along with our legendary, made-in-house bearings, and finish them with a one-piece axle that delivers laser-precise bike handling. In s
