Braking power modulator for a bicycle brake

摘要

A braking power modulator 2 is provided for a bicycle brake to modulate a braking power corresponding to a stroke of an inner wire 10a of the brake cable 10. The braking power modulator 2 is mounted midway along a brake cable 10 for the bicycle brake. The braking power modulator 2 is adjustable to provide different braking powers for different riders or different road conditions. The braking power modulator 2 basically includes a tubular portion 20, a first blocking portion 22, a second blocking portion 24, a biasing member 26 and an adjusting member 28. The tubular portion 20 has a first end 30 and a second end 32 with a longitudinal axis extending therebetween. The first blocking portion 22 has a first cable bore 46 and is coupled to the first end 30 of the tubular portion 20 for axial movement within the tubular portion 20 along a predetermined modulator stroke. The second blocking portion 24 has a second cable bore 66 and is movably coupled to the second end 32 of the tubular portion 20. The biasing member 26 is disposed in the tubular casing 20 between the first and second blocking portions 22, 24 under a pre-loaded state with a pre-set compression force. The adjusting member 28 engages the biasing member 26 to change the pre-set compression force of the biasing member 28 without changing the predetermined modulator stroke of the first blocking portion 22.
