I am building up an old GT Outpost trail mountain bike frame and i'm having some issues finding brakes that work. the bike came with a rear canti brake. The problem with that is the rear cable stop is on the front of the seat tube (closest to the handlebars) and directly in the middle. Obviously I cannot use this stop because the cable would then have to rub on the side of the seat tube and then would not be directly down the middle to set up for canti brakes.
I put a set of v tektro v brakes on, and the first thing I noticed was there wasn't enough room to install the pads with the correct spacers. there simply wasnt enough room between the brake arm and the rim. These are standard brake pads, not big fat ones. Then I cheated and took out a few spacers just to see if it would work, and the brake set up fine, but had no stopping power. no matter how tight I set the cable, the lever would squeeze all the way in to the bar.
I believe the levers were canti levers, which could explain why the v brakes didn't have enough power.
What are my options? I will get new v brake levers if needed, or I have no problem using canti's.
Here's a link to pics of the brake area
thanks in advance
