Hi, Busted my 9speed derailleur on last nights ride. tempted with 10 speed... So, thats a 10 speed mech and 10 speed shifter, but will 10 speed chain run with the existing rings up front??
yes.
Plus a 10spd cassette
Assuming the rings aren't too worn you'll be fine. How worn is the 9spd chain & cassette? If they're pretty worn then go for it, if they have plenty of life left, I'd be inclined to keep them a bit longer.
Thanks for the info. Bigyinn, you're correct. Pleanty of life left in the cassette and rings, etc. I'll probably just put new 9 speed back on as it is probably waste of £££ trashing a new system in the winter mud. I'll wait for everything to wear a bit more.
I just liked the idea of new clutch thingee on + versions of 10 speed mech. It wont make me go faster... or will it?! 🙂
^^What BigYinn said^^
Little point in going 10-speed if you're chain and cassette are relatively new. Replacing the mech, shifter, chain and cassette in one go will be pricey.
