How long would a standard 105 Chain Last?..
as in how many Kms can i usually get out of it?.
cheers
Life of a bicycle Chain
Never talk about km as wear is defined by the "stretch" in the chain. You just need to measure it. There are various ways of measuring it and the easiest for me is shown by the schematic below with a vernier caliper. ≥132.60mm and it's time to replace.
since chains are based on imperial meausurements, I use imperial measurements to determine when to replace. I measure 12 links, which are exactly 12 inches apart.
If the 12 links of the chain have stretched less than 1/16th of an inch then you should replace the chain, and you probably have not damaged the cassette.
If the 12 links of the chain have stretched past the 1/8th of an inch mark then you will need to replace the chain and the cassette (and possibly the chainrings too!)
Chains don't actually stretch, but the wear on the pins gives the impression of stretching.
Sheldon wrote all this up some years ago here.
Now onto chain life in Sydney for road bikes. I reckon I'm getting 10,000 km out of my road bike chains, but they are thicker than current 10-speed chains, so wear takes longer. I need a new 10-speed chain and I think it's done less than 5,000 km. I tried a new lubricant as an experiment, which I think shortened my chain life. Bob from Stanmore Cycles tells me he gets 18,000 kms from his road chains, but be warned, he uses only the best (Record) chains, is religious about washing his chain, and lubricates immidiately and repeatedly with the very expensive Campagnolo Superlative Chain Lube.

thanks for all the infomation
well the LBS told me my chain was gone after riding it for 2200kms since OCT 08. so i bought a Sram hollowlink chain and got them to do a service while i was there.
the chain was $110, $10 for the labour to put it on, service was for free as it was still within the 6month period.
went out for a ride today on certain gears the chain still does not shift, it also jumps on a few gears as well is there anything els i should be worried about?.

If the derailleurs are correctly adjusted, then there's a possibility that the cassette is also worn.
But I am curious of the chain being worn after only 2200km of fair weather road riding. Also, I would suggest that you learn how to change the chain yourself. Mail order a good quality chain would cost you less than half of what you paid and the actual procedure is dead simple.

tried to actually adjust the derailleurs by my self, going off youtube videos and some sites, that did not go too well.
yes i was surprised too when he told me the chain was worn, however he showed me using a measuring tool.
The Park CC-2
i actually checked how much the Sram chain was on PBK, after delivery it was arounnd $100 doller mark, not to include the conversion fee that credit card company charges you.
i was wondering if anyone knew of bicycle maintenance classes that are on offer.

What kind of chain is that? Campy Record chain is cheaper.i actually checked how much the Sram chain was on PBK, after delivery it was arounnd $100 doller mark

How the heck did the LBS suck you into buying a top of the price range RED chain? At least you'll get a quick link on it that'll make cleaning the chain a little easier. Gosh!
Bike store very shonky.
1) Sells a SRAM Red chain instead of something like a 105 chain, for four times the price.
2) Tells you that the chain is worn, but never checks whether cassette is worn - 10 second job.
3) Installs new chain on old cassette, which we now know is skipping. This will guarantee that both your new chain (and current cassette) will be junk and need replacing within 3,000 km.
4) Despite service, bike still failing to work properly.
Shonky! shonky! shonky!

Gotta admit i actually opted to go for the Sram red chain, i was actually talking to a club member oneday. he advised me that the Sram chain or the Campy Chain are the ones to go.
but after finding out the price i was abit skeptical, but only getting 2200kms out of a 105 chain and mechanic advised the Sram chain will last longer. i opted for the sram. whats worse was the chain came with 114 links, when asked for the box and the left over links the mechanic said he binned it already.
as for the cassette he pointed out that theres a few blunts on it but said nothing to worry about.
as for the meantime i will be riding the bike @ slowies 2moro morning, was wondering if some 1 can take a look and maybe point out what els needs to be fixed? as iam not mechanical @ all.
and last of all riding the bike 2moro @ slowies will that cause any further damage?..
