Many aero frames now utilize an under-chainstay direct mount rear brake. Many of these frame designs don't offer much room, especially if you are using a crank-based powermeter. Tektro offers the T750R as a cost effective brake model for these tight requirements. Often seen otherwise as an OE part used by several major brands, the T750R is for rear use only, optimized for short pull brake levers, and is one of the more user friendly versions of this style brake. This side pull brake is as compact as possible and uses a noodle system similar to a mountain bike v-brake system, with a close leverage ratio and stiff, forged arms that provide even stopping power that is adequate for consistent and predictable rear wheel braking.

The P422 adjustable-angle cartridge uses Shimano type pads, so swapping pads you prefer for carbon rims is straightforward. The angle adjustment system is easy-to-use, and affixes firmly, with solid retention. A full 12mm of reach, effectively from 24-36mm, gives you considerable flexibility in set-up to match various rim and frame designs. At just 150 grams, this slick rear direct mount rear brake will keep you aero and under control as you seek the fine line between speed and control as you tear through the course.
