About Rim Brakes
Rim brakes for bikes use the sidewall of the rim to reduce speed, this is done by a pad on either side applying friction against the rim, which reduces your momentum. Road brake callipers have been redesigned over the years and now use a system called 'dual pivot' which means the brake arms pivot off centre to apply a higher amount of pressure on the rim to increase your stopping power. Most manufacturers use dual pivot callipers on the front and rear, but some Campagnolo brakes use a traditional single pivot on the rear to 'balance' the braking power, the logic behind this is that as you brake your weight shifts on to the front of the bike and as much as 75% of the braking force is applied to the front.

Product Q & A
Ask your questions and share your answers.
Would these suit - or - is there another type or brans that would?
ie can I buy a rear caliper to replace my front 4600 caliper and just reuse the bolt that I already have?
If not, what other brake caliper sets can I replace my 4600 calipers with if I have a Shimano Tiagra 4600 STI Double 10 Speed Road Lever Set?
Because the frame is not designed with close clearance in mind, this makes the length of the calipers critical.
Are these suitable for the job?
They measure as follows:
The center of the pivot bolt to the center of the brake block measures 74 mm for the rear caliper.
The center of the pivot bolt to the center of the brake block measures 62.5 mm for the front caliper.
They will be used with 700c wheels.
Welcome all advice!
How much do these weigh? Or alternate question, how much heavier are these than 105 brakes?
