Does anyone know what the purpose is of the triangular-shaped tire guides which are attached to either side of the caliper arms on brakesets? These tire guides are usually found on the more expensive brake sets. Are the guides supposed to aid with the insertion/centering of the wheels between the caliper arms?

(you can hold them together far easier than brake pads) I don't know if this is what they were intended them for, however. -the venn buddhist -- --------------------------------------------------------------------- is anything really trash before you throw it away? ---------------------------------------------------------------------

[[Sveiks]] My guess is that they are heat sinks.. I have them on mine, and on some steep, controlled descents, they take away the heat that can build up. Do not rely on them to lose heat though, best technique is to alternate from front to back to avoid heat buildup.. -- ~~ Mike Upmalis (mupmalis@watarts)<University of Waterloo>

Tire guides are designed to allow racers to change their wheels quickly -- in a race a wheel can be changed in less than a minute. Tire guides are pretty much extra weight on a touring bike.

Actually they're found on racing brakes and allow for rapid insertion of a wheel without hangup when its being changed under racing conditions

The reason for the guides is simple. Most of the high quality brakes are used on racing bikes. The reason for the guides on the brakes is to facilitate wheel changes. A good mechanic can change a rear wheel in a race in 6 to 10 seconds. Any thing longer than 10 seconds is considered an all day wheel change acompanied by abusive language from the rider directed at the mechanic. Centering of the wheels is acomplished at the rear dropouts with set screws in the dropouts (Campy and Suntour dropouts have these). Mike Walpole
