Might as well kill two birds with one stone -- here goes:

1. I have an Ultegra clamp-on FD, but it's 34.9mm - this frame requires a 31.8mm. Is this just a different part?

2. Frame has internal cable routing, but being European, it's on the left (I assume since European bikes use the left brake for rear as I understand it). As long as the cable doesn't bind, it's not a problem to still use the right lever for the rear brake, is it?

Thanks in advance!
