I have Avid Canti's on the rear of my road bike based on a cyclocross frame, but they are not Tir-Align. They are ok for the rear with STI and no traveller device or what ever the device is called. On the front I prefert the Avid Vs, again with no traveller. V's on the back were way too powerful and I would have to have added a traveller. Canti's are perfect for reduced braking IMO.

Set-up is not too bad.
