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.
