Hmm, does seem alot of money, so i went through a few web sites and got a price of all the parts needed to do it yourself;

Tyres, chainring, pads, chain, cassette, bottom bracket, bartape, cables, cadence sensor..... £247

Obviously the rim and rebuild you couldn't do, or the front wheel bearing, so if that gets added... £ 89

That makes £336 plus labour to fit bearings, so say £350.

So if you got all the stuff yourself and did all the work yourself (except wheel and bearing), you would have saved £215, but as you say, you've got peace of mind and you didn't have to get your hands dirty

I just found a forum where they are discussing how poor the chainring life is of the shimano chainsets, some guy said they were made of grey cheese, and im beginning to believe him , just checked my Dura ace outer chainring and most of the teeth are hooked. My chain had always been well lubricated and had stretched quite a bit less than a 16th of an inch, well within the limits. The sprocket teeth seem perfectly ok tho . Has anyone else got the same problem, best go and check

Well Alan you know it's always going to be cheaper to do it yourself but if you're happy with the result and the peace of mind then no real problem. It also depends on whether you actually like fiddling about with bikes or not as to whether you want to do it. Personally I like to and tend to keep an eye out for good deals on things like chains, brake pads, tyres and the like which get regular changes as it's never a problem stock piling a few of these bits as they soon get used. Similarly with cassettes and shifters it can be worth keeping an eye out and picking up deals when manufacturers are trying to flog their new toy and discount "older" stuff - as we all know once it's a year old design it stops working and you can get some very good deals. If you're running a compact and getting through the 50 ring quickly could be worth adding to the list.

Steve, that is really poor considering the price of the top end equipment. My Chorus and Record stuff last for ages (3 years so far for my cassette and chainrings) and I would have expected Dura-Ace to have a similar lifespan. It tends to be only the commuter/winter bike where I use lower spec kit and it gets a harder life in the grotty weather that speeds things up.

Decided to look in to this chainring wear a bit more. I found a close up pic of a brand new chainset and compared it against mine and the pictures of the worn ones on this other forum i found.

It looks like the teeth on the outer chainrings are manufactured with a slight hook on them, they definately look different to the very normal shaped ones on the small ring. Its not something you look at when you first by a chainset. With the slight polishing to the metal done by the chain, it certainly looks as if the teeth are worn, but in fact are not, so I think mine are ok . The teeth in the pictures from the other forum seem to be worn laterally from the side of the chain rubbing when using too big a sprocket when on the big ring , certainly something to be avoided folks.

Conclusion; dont ride on the big sprockets while in the big ring, and dont panic if the teeth on the big ring look a little like shark fins, thats how they were made

[quote]I did shop around and ordrered from 4 or 5 different places but its well worth doing, saved myself at least a good £65.

[quote="Mike I"] By shopping around for parts and building it myself I spent a whopping £2,000 less than I was quoted for a complete bike.

what's that old saying?

Shimano wears out, campagnolo wears in?[/quote]

Or in the case of discussions on this forum "history repeats itself"[/quote]
Wasn't saying that Alan, just a comment on expecting a certain standard for a certain price - regardless of manufacturer.[/quote]

Oh, so sorry Andrew, I misconstrued your comment as in favour of Campag and against Shimano, repeating the oft quoted and somewhat sterile discussions reminiscent of the black sock white socks non-debate. Of course now I realise you were simply offering some neutral and helpful commentary I stand deeply ashamed
