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 machined sidewalls for smoother braking and single eyelets to help prevent spoke pull-through, which means higher spoke tension is possible.
Available in 36-hole 20 and 24- and 28-hole 20 and 24 x 1 1/8-inch sizes in anodized red, blue, gold and black. Cruiser rims in 24 x 1.75-inch are available in black and gold.
We recommend a spoke tension of between 110kgf and 130kgf. 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.
