I’ll be honest, half of the rim wear with V-Brakes on the pompino is my own fault as It doesn’t get cleaned all that often, Its set up Fixed for the commute so I can ride home, throw it in the garage and not really care about it. A liberal coating of very wet chain lube once or twice a week and just ride on. It takes abuse. And the rims will be coated in gunk which won’t help.
But I rode my old winter geared bike quite similarly and never wore a rim through using road calipers. I am on my 3rd rear rim on the pomino in 3 years!
They have much more leverage. Its overkill mostly as you will lock the wheels up long before you reach the limit of the brake power. They are better in the wet than the cantis but maybe its because i dont pull the cantis hard enough on the CX bike
I still like the V-brake with proper SS V-brake levers on the pomp though. But i only got them as I was a canti Noob and couldnt get my old frogs legs set up right. Since racing CX I would happily ride Cantis on the road again.
I would never, ever consider racing CX on V-Brakes. Cantis clog bad enough as it is.
