I have a 50cm kilo TT, currently have 25mm gatorskins that clear fine, but looking to put 28mm tires on. Stopped by LBS to see if it was possible and LBS dude said it probably was, the only problem being my front brake caliper. Right now I just have the stock Tektro r350, which is basically horizontal over the top of the tire. LBS guy mentioned if I switched to something with a bit more of a cut out over the tire I’d be able to clear 28s.

Anyone have any suggestions for appropriate front brake caliper with more of a cut out that would help fit larger tires? I use the front brake quite often but mostly just looking for a more approporately shaped caliper, don’t quite need to ‘upgrade’ to something ‘better’

thanks!
