The reach required for a particular installation depends on the frame construction (how low the brake mounting holes are) and the rim diameter. Generally, shorter-reach brakes work better, due to the reduced potential for flex and the higher mechanical advantage. Long-reach brakes must be of especially stout construction and have long arm extension between the pivot and to the cable attachment to overcome these problems. Cantilever brakes and disk brakes avoid these problems, though they have other problems. | The reach required for a particular installation depends on the frame construction (how low the brake mounting holes are) and the rim diameter.

This caliper has a reach range of 39-49 mm. As shown, with the brake shoe adjusted all the way up, it measures 39 mm from the center of the bolt to the center of the brake pad. | Datei:Caliperreach266.jpg|This caliper has a reach range of 39-49 mm.

Some people refer to "short-reach" "normal-reach" and "long-reach" calipers, but this is a recipe for confusion, and such terminology should be avoided. As fashion has changed, the 47-57 mm size that used to be "normal" has become "long" and the longer-reach Reach Markings on Shimano Brake Calipercalipers have become nearly extinct, aside from very long BMX calipers. | |||

Currently, "short-reach" calipers usually offer a range of 39-49 mm. This has become the de-facto standard for "road" calipers, and can now be considered "normal", though it is also correct to call it "short." | Currently, "short-reach" calipers usually offer a range of 39-49 mm.
