I'm upgrading various bits and pieces on my bike so today I bought some Shimano 105 brakes. I've just tried fitting them but the pads don't seem to slide down far enough to clear the tyres, they seem to catch by about 2-3mm. (pics show them as far down as they'll go).
Am I just being stupid and there's some secret adjustment that I've missed or have I just bought the wrong brakes or something?
