Title: Guy wire suspension device for center-pull type caliper brakes for bicycles

Abstract: There is disclosed a guy wire suspension device for center-pull type caliper brakes for bicycles, comprising a suspension unit provided with a groove for receiving at least two guy wires interconnecting a pair of arches, and a brake operating Bowden cable inner wire fixing unit to be integrally assembled to the suspension unit transversely of the latter, the arrangement being such that the at least two guy wires received in said groove are equally divided by the inner wire of the Bowden cable vertically inserted into the suspension unit so that at least one guy wire exists on either side of the inner wire, and that the lower end of the inner wire extending through the suspension unit is fixed by the fixing unit at a position below the level where the guy wires are received, thereby assuring the application of an equal upward force to each guy wire for secure and stabilized brake operation.
