I use this
dual pull handle and throttle combination in one unit on both of my bikes. On the old bike I always found it hard to adjust the brakes and on the new one I simply CANNOT get it adjusted so that I have enough stopping power without constant brake pad rubbing. So I came to the conclusion that maybe this brake handle wasn't meant for V-brakes. I will put a normal single pull V-brake handle on my new bike tomorrow and see what happens. Unfortunately it means I wall have no front brake while testing.
