    Uprading from Sora

    I am interested in upgrading from my stock Sora components on my commuter (Trek 1000), mainly because I would like to be able to shift while I am in the dropped position…and I would like better brakes. Money is a concern especially since I am guessing that I will need to upgrade to a 9sp, so that would add a front crank, rear hub….ect. And I don’t really want to invest more than what my 2003 Trek 1000 is worth.


    Is there a viable 8sp upgrade for shifter/brake lever & brakes? Or would I have to do the 9 sp upgrade? I am only familiar with Shimano, so I don’t know what the other companies offer.

    Ask iamtim about this - he recently upgraded his Trek 1000 to all Tiagra components. I am in the process of upgrading my all my Tiagra components to 105 (9-speed), and there are good deals to be found right now on 9-speed 105 stuff because they discontinued it.

    You can get by by just getting a right brifter and a 9 speed cassette with a 9 speed chain. 105 parts are going for a fairly reasonable price right now, especially the black finish bits.

    You bike is worth as much as you want out of it.
    Bikes use brakes to stop.

    If your bike has breaks, don't ride it.

    Dan is right. You don't need a new crank or rear hub. 8-speed freehubs are the same width as 9- and 10-speed.

    It's true that you really only need the rear (right-side) brifter, but it's hard to get them except in pairs, so you may as well buy the 9-speed set of Tiagra or 105.

    shifters, front der., cassete, 9 speed chain. If found that the sora FD didn't work well with the 105 ****ers and it is a cheap part, really. tiagra brakes are great. The sora crank will work fine.

    You may be able to find NOS 8 speed brifters but I wouldn't bother. The 105 9 speed stuff can be had for reasonable prices and will likely be sevicable longer.

    So to upgrade to Tiarga or 105 i would need new:
    Shifters/Brake Levers
    Front & Rear Derailers
    9sp chain
    9sp cassette
    And a new bottom braket?

    But no crank or a front & rear hub?

    I upgraded a C-Dale from Sora to 105 and the 9 speed stuff worked great. I'm also riding Ultergra and Dura Ace, but find that I actually like the brake lever/hoods with the 105 better... fits my reach better for some reason. DieselDan is right, the stuff is a bargin right now.

    You do not need a new crank, bottom bracket or hubs (unless you want them). I don't think that you actually need the RD, either. The number of speeds is controlled by the shifters and cassette.

    The big money's in the shifter. Once you get that a cassette, chain and (maybe) a front derailleur will 9-speed you.

    If you just want to shift from the drops go to bar end shifters. I have sora drs on my Trek 500 and like the bar ends. I am running triple chainring and seven speed cassette.

    I forgot the about barend shifters. Much more economical then new brifters, and you could just use your current Sora brifters as brake levers.

    If your bike has breaks, don't ride it.
