i want to replace my 9 speed sora triple chainset with a tigra 10 speed triple chainset, but 10 speeds dont say they are compatable with 9 speed, what is the difference between 10 and 9 speed chainsets, was originally going to get a 105 or ultegra chainset but just too exspensive.

Comments

  • You can swap them without any problems a 9 speed chain will work fine with a 10 speed chainset.

    I have to ask why you want to change it though as there won't be any performance improvement.

    If you are changing because the Sora is worn out then it makes sense although replacing with a Sora chainset might be cheaper.

    No they're just a bit lighter, more cycling will improve your performance.

    Hmmm. Tiagra & 105 should have performance improvement over Sora - should shift better, etc

    But I'd wait until my Sora was worn/ ready for replacement.

    I upgraded a 2300 groupo (which is actually below Sora) with 105 on my Allez.

    The shifters themselves were nicer, but better shifting performance in actual use?...maybe.

    It's a question of marketing over experience really. 105 is clearly meant to be better, but the objective difference in use is very small.

    More importantly the difference between a well set up derailleur and a badly set up one is night and day.
  • If there is any shifting performance improvement (?) it will come from the transition grooves on the cassette not from the shifters as their only job is to pull or release the cable.

    I agree with hipshot it is marketing and we are meant to believe it is better.

    But if you are buying for bling or kudos reasons as opposed to performance then go for it I do all the time but then again I am a bling kinda guy.

    I don't agree. I have SRAM Apex on one bike and SRAM Red on another, but often swap wheels around so use the same cassette with both groupsets. Red shifting is miles better than Apex. That's not to say Apex is bad, but it's nowhere near as quick and smooth as Red. It'd be great if Apex was as good as Red, but it's simply not (people do say that Force is just as good as Red though).

    I'm sure the same goes for Shimano and Campag groupsets.
    More problems but still living....

    I understand that one is better than the other and that you are really pleased with your choice.

    But miles better and nowhere near as quick, really? How fast can shifting be?

    Ive tried SRAM Red, it's really good, but it's not transcendental :D

    Yes, really. Makes no difference to me if you don't believe me. The Red came with a bike so it's not like I spent sh!tloads on the groupset and now have to justify it to myself by saying it's great. It really is MUCH better than Apex. Shifting when out of the saddle is always a good test for just how slick the shifting is and there is a big difference between the Red and Apex (and yes both groupsets are properly set up).

    Whoa chill man, it was nothing to do with not believing you!

    I was just making a point about the kind of language we use when discussing components, apologies.

    Really glad you like your groupo.

    (note to self - use more smileys)
  • I too have Red that came with the bike and to me it is no different to the 9 speed Tiagra I have on another bike.

    To put it simply I press the lever and it changes gear on both, that is all I wanted it to do and they both do it. I am happy!

    Imho performance/speed is about how hard you pedal not how quickly the gear changes or how smooth they are.

    The OP was talking about changing the chainset not groupset.
