Some component questions:
1) I've decided to go STI on this build, because I think its cooler. Just a personal choice. Are the Shimano Sora (ST3400) shifters of a decent enough quality to last a while? How does it feel with the thumb downshift, vs pushing the whole lever? Alternatively, are there any other equivalents in price?
2) I read about the 105 RD being worth the extra money - is this just for weight, or is it that much better of a shift? I dont need them to be crazy crisp, just solid enough for me to ride on and not be annoyed with.
3) On my fixed gear, I need a front caliper with a little more clearance than the Tektro I have now. Is the Dia Compe BRS100 I should look into? Or does anyone else have a more-clearance caliper suggestion?
