Greetings all,
Due to decreasing shifting performance along with a bashed up RD, and the knowledge that both my chain and cassette were worn, last night I replaced all three on my Triban 3. I've gone with a HG50 12-25 cassette, KMC chain and Claris RD.
Everything works fine except when in my big chainring, if I put down lots of power the chain comes off the chain ring. Now I've done 6000+ miles on this chainset and it hasn't admittedly seen the best of care. That being said, the cage on the Claris RD is about 1" longer than the 2300 RD I was using, but then the RD cage doesn't look particularly stretched or at too jaunty an angle.
So my guess is the reason it's doing it would be the chainset is worn. Does anyone agree with me? Assuming that's the case, what tools will I need to install a Claris Triple chainset? Some research has suggested to me my current BB is square taper whereas the new Claris one would be Octalink, so I assume I'd need a new BB. Also how can I go about finding out what crank length I need? I also saw something about "chainline", I now know what this means but do not know how I'd find out which BB I'd need to match my set up.
Any help much appreciated!
Thanks, Tom
