This nifty little design will enable you to use standard road brake/shift levers or any non-V-Brake style lever. The roller wraps the right amount of cable to adjust the throw of the lever to match the amount needed for your brake. Easy to set up and durable. Perfect for running V-Brakes on your cyclocross bike.
I used a pair of these in re-purposing the flat bar road bike that got me into cycling into a drop bar commuter. It came stock with eight speeds and a triple; I found a used set of eight speed triple RSX brifters and used the Travel Agents with the V brakes. With 700x32 tires, I've got a fast, comfy commuter that stops better than my road bikes.
Pros: Easy installation; doesn't look out of place.
Cons: Tight fit in the noodle clamps on my bikes.
