Reserve 48|53 GR DT 180 700c Wheelset If you're not first, you're last. The Reserve 48|53 GR is the fastest off-road wheel Reserve has ever made. Built specifically for aero gravel racing, the 48|53 GR uses a super-wide external profile that allows air to glide uninterrupted between the tire sidewalls and rim for a noticeable aerodynamic advantage. A 30mm internal width creates a wide-stance tire profile for a larger contact patch and better grip at speed. Reserve's new hollow-bead design shaves weight from the outermost section of the rim while also better resisting pinch flats. This DT Swiss 180 EXP hub build pairs that race-ready carbon rim with one of the most trusted, high-performance hub platforms in the business. Features Aero gravel-specific rim profile with a super-wide 44mm external width that lets air flow cleanly between the tire sidewall and rim for real aerodynamic gains on road and gravel30mm internal rim width creates a round, wide-stance tire shape for a larger contact patch, better grip, and lower rolling resistance across a wide range of tire volumes Hollow-bead rim design shaves weight from the outermost section of the rim where it matters most, while also improving pinch flat resistance Asymmetric rim offset (2. 8mm) improves spoke angle and tension balance for a stronger, more durable wheel build DT Swiss 180 EXP 36T hub delivers proven, trail-tested reliability with a 36-tooth engagement system for quick, responsive power transfer XDR and HG freehub compatibility to suit SRAM and Shimano drivetrain configurations Centerlock rotor mount compatible with standard disc brake rotors SPECIFICATIONSWheel Size700c Hub DT Swiss 180 EXP - 36TRim Depth48mm Front / 53mm Rear Internal Width30mm External Width44mm Asymmetric Offset2. 8mm ERD545mm Front / 535mm Rear Spoke Count24Freehub XDr or HGRotor Mount Centerlock Hub Spacing100x12mm Front / 142x12mm Rear Recommended Tire Width40 to 57mm Wheelset Weight1, 433g Intended Use Gravel, Road | Reserve Wheels | Reserve 48 | 53 Gr Dt180 700C Wheelset Set, 12X100/12X142Mm, Centerlock, Xdr And Hg11R
