My bike is sick - help!

Econoline Van

I have an Olmo road bike with Campag Veloce parts. It's a fair few years old now and the teeth on the smaller chainring are worn down, resulting in the gears slipping/grinding everytime I push off from a standing start.

I'm hopeless at maintenance and money is an issue, where's the best place to bring it? And can I just replace the chainring or will it need other new parts to go with it?

When you say "smaller chainring", do you mean at the front or at the back?
If it's at the back, you'll need a new cassette and chain. If it's at the front, you can get away with a new chainring, but if you've never replaced the chain & cassette you'd probably need to replace all three.

Any bike shop can handle this.

At the front. I've never replaced anything on the bike save for the tyres and brake-pads. This is sounding like it might be expensive.

Quick look on wiggle says that a cassette is around €50, chain another €50, and €40 for an inner chainring. I don't know if Campaq are standard parts though, you could easily get a cheaper chain & cassette in standard sizes.

I'm assuming it's a double crankset. 10-speed?

If you've been using the bike frequently for several years with the same chain, then I think you might have to change the whole drivetrain.

9-speed.

You can use any 9 speed chain certainly, maybe any front chainring with the same BCD, but will probably have to go for a Campagnolo cassette. Certainly should be able to get it a fair bit cheaper.

Thanks for the replies.
Anyone recommend a Dublin bike shop for me to bring it to? I'm yet to ever enjoy a visit to a bike shop in this city.

You won't get away with anything but Campaq components on the back wheel it would appear, the spacings are ever so slightly out. If you use shimano components (for example), some gears will work, but some won't and never will.

So you will need:
A cassette
A chain
An inner chainring

An outer chainring is not essential, but I would strongly recommend it. You'll need a 135mm ring for the Campaq.

Total effort for a replace is about 30 minutes. Well, you could do it in 10, but I'd "budget" 30 minutes. Not sure what a bike shop will charge for that.

If I was to do it myself, I would completely strip down and clean the drivetrain, replace the cabling, perhaps service the wheel hub(s) and pedal bearings. But you could limp along without getting this done.

Thanks a million Seamus, that's an enormous help!

alfalad

Bring it to mister skeff and he'll show you how to do it! He has an advert in the cycling ads section. he doesn't supple the parts but will do the work.

Actually.. I have a brand new campagnolo veloce, (square bottom bracket). It's 10sp but will work perfectly with 9sp.

Bought it by mistake for 50 euro, forgot to send it back and am stuck with it now. You can have it for 30 if you like
