Riding a rigid bike on washboard roads might look great on Instagram, but 80 miles in, you’ll be grateful for every bit of cushion you can get. The Reserve 25|GR is designed for gravel bikes, and supports a 40-55mm 650b tire, delivering extra traction and a bit more cushion than a 700c wheel, thanks to the additional air volume. The hookless design belies its mountain bike provenance, and J-bend spokes and external nipples make it ideal for long tours where replacement and repair isn't so much a matter of if but when.
Reserve uses externally reinforced spoke holes to strengthen the area where the rim sees the most force, around the spoke nipple. This provides for improved strength without adding unnecessary weight.
High Volume
The 25|GR 650b rim was built for wider, high volume tires that eat up washboards and keep you comfortable on long gravel missions.
Asymmetrical Design
Asymmetrical rims front and rear make for a stiffer, stronger and more reliable wheels by improving the bracing angles and equalizing the spoke tensions between the drive and non-drive side spokes.
