Box One Rear Race Rim

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. Note: 99 lbs rider weight limit for 20 x 1 1/8″ (451mm) and 24 x 1 1/8″ (520mm) rims Product Specs WHEEL SIZE: 20″ SEAM: Welded ERD: 394-596 HEIGHT: 14.3mm WIDTH: 17.5mm SPOKE HOLES: 24-36 WEIGHT: 20” x 1.75 (406mm): 362 grams/12.7 ounces 20” x 1 1/8 (451mm): 280 grams/9.87 ounces24” x 1.75 (507mm): 432 grams/15.2 ounces24” x 1 1/8 (520mm): 343 grams/12.1 ounces
