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 1.75 rim, for example, weighs just 362 grams/12.7 ounces. Strong and true, Box One rims have single eyelets to help prevent spoke pull-through, which means higher spoke tensions are possible. Available in 36-hole 20 and 24 x 1.75-inch, and 28-hole 20 and 24 x 1 1/8-inch sizes. Meets or exceeds ENBMX standards. Please note, Box One front rims 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) and 24 x 1 1/8″ (520mm) rims
