    Some Component Questions (Sora STI, etc)

    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?

    Thanks.

    105 shifters are built a lot better and will last longer. Go to any LBS and try 2 bikes with both these shifters, its that different.

    I have Sora on a low-end bike, beat it up pretty good over the past year, and it's still fine. The little red arrows are now out-of-whack, but I "know" what gear I'm in anyway. If anything is ready to catastrophically break, it's given me no indication. I keep the cables tensioned correctly, ensure everything is tightened, etc. basic maintenance.

    I have no problem with the thumb shift. Sure, you have to move your hands if you're in the drops, but so what? It's a minor inconvenience. I have another bike with 105 shifters, and while I will definitely say 105 is superior, I won't say Sora is terrible.

    One thing I like about STI in general (at least most STI - this won't apply to some Dura-Ace and Ultegra) is the ability to mount a Mirrycle STI mirror. In my opinion, that mirror offers excellent rear visibility without looking out-of-place on your bike.

    I've got Sora on my commuter and Ultegra on my road bike. The Sora works fine (over 4K miles so far) but the thumb shifter is not as nice as the lever on the higher groups IMHO.

    6000 plus miles on a Sora group here. Can't say I've noticed any changes in performance.

    Sora absolutely works fine but most people absolutely HATE the thumbshifter. I've never heard anyone say what you said about a 105rd being so much better than a sora. Sora RD works fine but if you crash, it's toast because it's all plastic. Consider microshift brifters if you really want sti at a good price point. I have them on 2 of my bikes and they are excellent. NAshbar has the 10speed version and usually on ebay you can find the 9speed version if you prefer a 9speed. i find 9speed casettes/chains, etc to be cheaper to replace.

    There is also a nashbar microshift RD available. I have the MTB version on my commuter and it works great and looks better than the pics of it.

    survey sample on that is... ? or just your opinion.


    shimano has numerous price points and the YGWYPF thing still applies ..

    But the lowest price point stuff works surprisingly well
    if you give the mech enough time to do it's thing.

    like .. don't do front shifts in the middle of a steep hill , etc..

    Dont be a dick, you know damn well that pretty much nobody actually LIKES that thumbshifter. everyone either hates it or is willing to deal with it because of the cost savings but nobody ever says "man, I really like that thumbshifter. My sample size is no less than 1000 posts on this forum alone. you will notice that I did say that on a functional level it works great; it's not necessarily going to break or wear out on someone any faster than the other offerings it's just that the ergonomics suck.

    sora levers work great in the winter with big fat gloves. 2 distinct motions for shifting. sure you cant shift in the drops but if you ride the hoods it works just fine
