Outfit the Reserve Wheels Reserve 25|GR rim with a 40–55 mm-wide 650b tire to achieve extra traction and a bit more cushion than a 700c wheel provides on gravel thanks to the additional air volume.


  • Rim bed shape eases tubeless installation, utilizing offset spoke holes that allow the tire to easily push past the bead bump to seat tubeless tires
  • Asymmetric rim makes for a stiffer, stronger and more reliable wheel by improving the bracing angles and equalizing spoke tensions between the drive- and non-drive-side spokes
  • Externally reinforced spoke holes strengthen the area where the rim sees the most force—around the spoke nipple
  • This provides improved strength without adding unnecessary weight
  • Rim bead is hookless, making for a better fit with modern tires, but also simplifying manufacturing, which results in more consistent carbon compaction and a stronger rim
  • Offset: 3 mm
