New chain ring.

willhub · Post by **willhub** » Mon May 12, 2008 12:41 pm

My front big chain ring is bent so needs replacing, would it cost more going to a bike shop buying it from them and having them fit it or cost more buying it from an online shop then having a bike shop fit it?

Also anywhere to get cheap outer rings? I cant afford the prices of new.

I am going to risk giving some advice on this.You could take it in to a bike shop and get them to have a look at the problem and ask their advice.I would recomend Nigel at Haxby Cycles.Or you could ask if any club member would be happy to help if you took the bike and new chain ring over to their place.I am sorry but I don't know how to fit one.

Try the for sale or wants thread some one may have one

What do you mean you are going to risk giving me advice? Its not as if its bad giving me advice surely?

I could possible try and take it over to nigel in haxby one day after college when I have worked out a way to get there. The way there looks abit busy aswell guess I'll get my dad to take me.

Never knew they had a website

thanks.

I'm no mechanical expert but (assuming it's a standard chainset you have and not a rare or exotic item) I'd have thought it would be possible to buy a chainring and fit it yourself - it's only 5 Allen Bolts isn't it? There's nothing like doing a job yourself to learn the pitfalls and tricks of the trade!

Seriously though I'm sure that most members would be happy to help you fit it if finances mean that getting one cheaply online is the best option for you.

EDIT: As a club member remember that you get a 10% discount from a number of local bike shops (LBSs) - may be that they will be almost as cheap as Ribble etc

As Dave says, fit it yourself. What size do you need and is it Shimano or Campag? People may have some spare rings you can have cheaply.

Well the actual chainring on at the moment is an RPM, but on the actual derailleur it says Shamino Tiagra.

I am getting confused now, on closer looking it seems both of the chain rings are bent, must be the whole chainset??? Could it be on wrong or something? Maybe I should take it to the bike shop afterall?

How local is local? Spa Cycles in Harrogate may have something to suit from the Stronglight range without paying the earth (a reluctant recommendation having had some pretty apathetic customer service from Spa re. Campag-compatible bits - they seem to have some sort of aversion to stuff from the Vicenza company - in recent months).

Local to me is Selby Bike center but wont have the 10% discount, closest place to me is any bike shop in york but haxby is pushing it abit and will find it hard to get there unless I ride my bike there.

Might take it to york cycleworks.

Campag is 135BCD (bolt circle diameter)
Shimano and 90% of all other brands are 130BCD
You could order online from wiggle etc or pop down to cycle heaven or one of the other local shops.

By the time you've added postage its sometimes as cheap to go to LBS

Why not buy a cycle maintenance book? There are laods out there, learn to do everything yourself. You only need a few special tools to do the bigger jobs which aren't expensive. Its not difficult.

In my opinion, paying someone to fix your bike is insane! What if something goes wrong in the middle of nowhere and you've no idea how to even start fixing it? Plus you'll save so much money.

Every time there is a problem I learn so proberbly wont need to go to get it fixed eventually just like I learnt with computers and now I think it would be insane to pay to get a computer fixed as I can do it all myself. I will look around for some maintanance guides.

Do fulford cycles and all that charge to have a look at your bike and see what might need doing? The only bike shop apart from halfords I have been in is selby bike center and he said he would have to take my bike in to have a look at it but would cost like 10 quid an hour, all I want to know if what might need doing as even though the front chainset still works, its really bugging me that its bent or not in properly!.

Am I the only one wondering how you bent the chainrings? I remember bending a steel one years ago but they're quite tough now. Even on the MTB landing on rocks I just take teeth off, never bend them.

I'm just wondering whether you're barking up the wrong tree and something else is making them seem bent (e.g. loose bottom bracket). Or have you stood on them??? Even if they are, and they're unworn, some careful work with a vice should straighten them again.

Incidently, RPM is just re-badged FSA. They do various models with different BCD chainrings so if you're going to buy online you need to measure first.

On closer looking it appears both chainrings appear to be bent, and the inner one is unlikely to get bent so it cant be bent, the whole chain set appears to be bent but god knows how that is happening and I havent a clue on how to correct it, I want to get it looked at but I dont really want to pay anything to just have someone experienced look at it and tell me what needs doing.

Drop in to Cycleworks and they'll tell you what's wrong + how much it'll cost to fix it.

Otherwise if you can get into York this evening, I'll have a look at it for you.
