Worn jockey wheels - Rear Mech

edited October 2010 in Workshop
As you can tell from my other recent threads, I'm building a winter trainer on the cheap. Part of 'on the cheap' has meant buying used pieces here and there, one of which has been the Tiagra rear mech I got today.

The seller said it had done about 5000 miles, approx twice what my Ultegra rear has done on my other bike and it still looks wear-free, so no big deal I thought. However when I received the Tiagra mech today, it was apparant that the jockey wheels have really worn, with the teeth being VERY pointy. Otherwise the mech appears fine so I'm inclined to keep it rather than re-sell it or get new jockey wheels (I only paid £7 for it so it's no loss) but I thought I'd ask what the likely problems are from using a mech with worn jockey wheels?

Any opinions or experience greatly appreciated.

    Judging by the prices of new wheels, even on ebay, I'd be just as cheap buying another used Tiagra mech!

    depends if you want the shifting to be fine or rubbish

    I've just seen these myself. Are they any good? More to the point, is changing jockey wheels easily done!?

    Jockey wheel changing is very easy. Just make sure you get the top one at the top and the bottom one at the bottom.

    Jockey wheels are jockey wheels... you can spend a lot of money for the fancy KCNC with ceramic bearings or machined aluminium... just to realise that the bog standard wobbly black Shimano ones work a lot better as they bend allowing more tolerance in the shifting process...

    So, really, it's difficult to go wrong. Fit some grease inside the aluminium cups and keep them clean, service them from time to time and they'll serve you well for ages.
    You know they need clean+ grease whn they squeek as you shift...

    Just send em back or re-sell. What's the point in buying 2nd hand rubbish on the cheap? It's not just the jockey wheels that wear, it's the spring on the mech also. A new one from Ribble or similar discount site will last you a lot longer for the same money as changing the wheels :wink:

    Bouught those Tacx wheels above for a tenner and changed them over in about 5 mins yesterday. Still got the cabling to do before the bike is road worthy but otherwise, I'm hapy that I've added another DIY job to the list of things I can do myself!
