Going from 105 to Sora

    My last two road bikes were both 10 speed 105.

    I recently changed to a bike with 9 speed Sora and despite my doubts after ordering it I have to say it is great.

    Gear changing only requires a very light touch on the shifters and changes sweetly every time.

    My utility bike has Tiagra 9 speed with bar end shifters and they also perform faultlessly.

    I really wonder if for the average cyclist (like me)who doesnt race then the higher end groupsets arent that much of a step up.

    Im a big fan of the Sora shifters with the thumb release for up changes. Brilliant for urban commuting up on the hoods.

    I havent ridden that style of Sora.I think that was a couple of models back.

    The new Sora is same as 105 with the 2 levers.

    The little that I can tell, it's more about length of operation between services and replacement than quality of operation.

  5. Provided you don't actually have a problem shifting (A friend of mine has small hands and she has - I think - Claris and she has difficulty with some changes) then what you'll probably find is that after a few rides you just get used to it, whatever it is. When I ride my bike with down tube shifters it takes about an hour to get back into the swing and then I just forget about it.

    I have a number of bikes with various set-ups, across the price ranges, Campag and Shimano, and I can honestly say I find no difference at all sitting here on my fat arse with them in my shed...

    Maybe my 10 speed (4400) setup was just rubbish, but I much preferred my 3500 Sora setup. Shifting was so much smoother on the Sora.

    Funny you should say that. I ride the bike with down tube shifters a lot and had great entertainment on my CX feeling about for shifters that weren’t there.:laugh:

    I find that having electronic control helps massively with docking with the supermarket bike bays. On the bike with tiagra i'm often miliseconds slower and often miss out on bogoffs.

    Plus I can change gears remotely according to the size of turnip I've chosen.

  10. I’ve got 5700 105 10 speed, Sora 9 speed with a triple up front, 6800 Ultegra 11 speed, and Tiagra 4700 10 speed, on my Shimano equipped bikes, and I like the Sora, because bits are cheap, and it’s the easiest of the lot to recable and adjust, on the fly. The Sora bike has the ‘unconventional’ tyres on it as well. Internet tropes would have you believe it’s an unrideable bucket of bolts. It isn’t, and it’s relatively cheap to keep running, which makes it ideal for big miles.

  11. The thumb buttons work brilliantly with thick gloves on too. Fantastic for riding in the winter, and cheaper than Campagnolo, that also have the thumb button levers.

    Generally speaking, all Shimano stuff works.
    The major difference I notice is when I change from my bike with Claris to my bike with Ultegra Di2. Both do their job properly, but the difference in feel and operation are streets apart.

    I reckon the only significant difference between the mechanical gruppos cited is weight.

    Feel is subjective. Having big hands the longer throw at the levers of Tiagra makes it the one I like the feel off the most. Ulty is tight and slick, but feels toy like and awkward in my manly mitts.

    I have 2 bikes with 9 speed Tiagra, one with 10 speed 105, and the latest addition has 11 speed 105.
    My preference is for the 9 speed Tiagra. I am not Bradley Wiggins so I could quite happily have 6 cogs at the back, as long as they ranged between 10 and 32 teeth (some big long climbs around here!).
    The more cogs at the back, the thinner the chain has to be, and the less miles it will last. Same for the cassette and chain rings too. And there lies the advantage - for the parts manufacturers and bike shops!
    I am trying to find a triple, 9 speed crankset for a 7 year old road bike and it's not proving easy... They want us to "upgrade" which will of course require new shifters as well as the transmission parts.

    What bottom bracket and is the BB shell screw in? Would have thought much cheaper (with same gear range) rather than switching to 10sp, to change the BB to a square taper (eg BB UN-55) and get a triple from Spa Cycles. Change from £50.
    Triple 48-38-28 (could put a 50 on instead): SPA-CYCLES-XD-2-Touring-Triple-Chainset
