the brakes that comes with the Kilo TT off BD has a very weird fit. I took a look when my friend bought his kilo back in May. If u swap the front brake for a cheapo Tektro front brake off bikeisland, ur tires will clear. Otherwise, what I did for my friend as a quick fix is just make the brake arms very close to the rim. When the arms are closer, the underside of the axle lifts a little. Just enough to clear his tires. Just that his brakes became really really responsive. So that's a quick fix if u wanna go that route. But my friend was running 23s. I'm not sure about 25s.
