Tech Tip: V-Brake Arm Lengths

Despite their age, our articles on v-brakes and v-brake conversions remain very popular with GRAVELBIKE’s readers. To help folks determine whether a certain brake will clear their bikes’ fenders or fat tires, we’ve compiled a list of popular v-brakes’ arm lengths (the list will be updated as new information becomes available).
