Box One rims have a no-nonsense low-profile design that eliminates excess material, making them some of the lightest weight double-wall rims available. A 20 x 1-1/8" rim, for example, weighs just 280 grams/9.87 ounces. Strong and true, Box One rims have single eyelets to help prevent spoke pull-through, which means higher spoke tensions are possible.
Please note, Box One lack a braking surface and are not designed to be used with rim brakes.
Note: 99 lbs rider weight limit for 20 x 1 1/8" (451mm).
