Focus 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, Focus rims have single eyelets to help prevent spoke pull-through, which means higher spoke tensions are possible.
20” x 1.75 (406mm): 362 grams/12.7 ounces (ERD 394) 24” x 1.75 (507mm): 432 grams/15.2 ounces (ERD 494) 20” x 1 1/8 (451mm): 280 grams/9.87 ounces (ERD 438) 24” x 1 1/8 (520mm): 343 grams/12.1 ounces (ERD 516)
We recommend a spoke tension of between 110kgf and 115kgf. But remember, every rim is different. The mark of a truly skilled wheel builder is the ability to find the highest tension a rim will allow while staying true.
Please note, Focus front rims lack a braking surface and are not designed to be used with rim brakes.
