We reported on the CDP TT brake calipers from US-based Simkins Designs late last year, and now the company has followed up with their new Road Race brakes.

They utilise the same patented coupled dual pivot design as the time trial brakes, are CNC machined from 7075 aluminium and use the same bearings and seals.

Here the similarities end. As road racers have different requirements from their brakes than time trialists, Simkins have addressed this by making the road brake more powerful, lighter and featuring more adjustability.

Extra power is achieved by increasing the leverage ratio to 2:1, and 25g has been shaved off. A barrel adjuster, absent on the TT brakes, is featured.

Unlike the TT brake, the RR brake is compatible for use with Kevlar brake cables. The brake cable wraps around the left tip of the right arm and tucks underneath the brake, and the cable tip is not visible after installation. Also, the springs are entirely housed within the arms.

The brakes have been extensively computer stress simulated, with every curve modelled, tweaked, and iterated for optimal strength and deflection.

Simkins says: “Our approach is to have clean, compact, utilitarian designs and the RR brake captures these ideals.”

A pair, available in polished or anodised, weighs a quoted 253g and costs from $274.99.
