New chain and cassette after 1 year?
Postby vinvin » Wed Feb 09, 2011 8:21 pm
My bike went in for service today (was due for it as hadn't been properly serviced since about Sept) and the bike shop (I don't want to name it but it's one that generally gets the thumbs up from Canberra cyclists) wants to replace the chain ($59) and cassette ($120) because they are worn and rubbing. I'm willing to trust them, but I'm just a bit surprised about it because I've never worn either one out before. I've been riding regularly on this bike for 12 months (bought new) but only about 80-90km or 2-3 rides per week.
Any thoughts? I have to decide ASAP because I have events coming up this weekend and next week!

Mod says - I know there's more than one bike shop on the street mentioned, but fairly obvious from the context which shop is referred to, to those in the know. Let's avoid naming-and-shaming, even if masked.

It would be Shimano 105 chain and cassette in all likelyhood.vinvin wrote:I'm afraid I can't name the chain or cassette, but it's a $2500-$3000 carbon bike with mostly 105 componentry/front set/brifters and ultegra on the rear derailleur.
12 inch (30 cm) ruler, measure the chain pins and if the last one lines up perfectly with the 12 inch mark on the ruler, your chain is like brand new. This looks to be a pretty good guide

Sounds about right. Push it for too much longer and you'll need to replace the chainrings too.vinvin wrote:Really rough estimate of use would be about 3500-4000km?

Mine had 3k, and like I said, chain was exactly 12" over 12 links. OTOH my Rubino's lasted about 2k where some report over 10k for similar tyres. As always YMM(and does)Vrkelsen wrote: Sounds about right. Push it for too much longer and you'll need to replace the chainrings too.

I've not done either, but can't seem to get more than about 2,500km out of a chain on my road bike. If I leave it for another 1,000km, it also chews up the cassette.Cruiserman wrote:bollocks only if you have been riding on the sand in the beach.rkelsen wrote:Sounds about right.

4,000km on a road chain/cassette is very good milage, IME.

Literally, in this case!Robdog wrote:YMM(and does)V
Only way to know for sure is to check out the cassette and measure the chain; there's always the possiblity someone is trying to rip you off or has made an honest mistake but the other possibility is that the OP should be thanking them for saving his chainrings and more $$$!
IMO It wouldn't be unheard of for the chain and cassette to be toast after 3-4'000 Km, especially if you've been a bit slack with cleaning/maintenace.

Shimano 105 bits. I've tried several different types of chain, but the best one was a comparatively cheap KMC. As far as lubes go, I've tried pro-link, r'n'r, purple extreme and even ordinary gear oil.Robdog wrote:What chain/cassette/rings are you using? Are you above average weight or power?
The reality is that these are racing parts. They're not designed for durability, which is why I don't commute on a racing bike anymore.
As for weight & power: I've never had my power measured and I weigh 102kg.

This has happened to me back when I didn't fix things myself. This same shop pushed very hard to replace all cabling and housing, and also just went ahead and did it with XTR stuff rather than doing like for like.Ross wrote:That's a standard thing for that unamed shop to say things need replacing when they don't. I know numerous other people that have similar stories.
I know now how to fix everything on my bike... except my shocks. You learn your lessons quickly when they are so expensive.

Another factor is how clean you keep things. For example, I when I ride at Sydney Olympic Park regularly I notice that brake pads get worn very quickly whereas riding into the City they last much longer. I am doing similar distances.
This is due to their being a fair bit of fine debris on the SOP roads which causes more rapid deterioration. I cleaned the bike once a fortnight during that time.
On my commuter I got 15,000 km's out of the first chain (probably way too much) and 15,000 km's out of the next 2 before I changed the rear cassette and one of the small chainrings (all Sora stuff). From what I'm told that is at the upper end of the scale.

I did much better out of my Sora bike chain (around 10K) than my 105 (around 5K). Sora is 9 speed, and wider chain, so I put it down to the benefit of having a larger load bearing surface on the wider chain.goneriding wrote:.

OP is a bit vague about kms, but the acid test is to follow Sheldon's recommendations and measure the chain with a steel ruler. Don't bother with the Park chain measuring tool - it over-estimates the wear.
Won't hurt OP to order up a chain and have it on the ready to go when it is eventually needed - will help him avoid the temptation to be such a tight-ass that he lets it go too long and wears cassette rings etc.,.

In one word, "Bollocks". Check the wear yourself with a ruler (on the chain), and have a look at the teeth on the cassette and see if you can identify and wear. My last cassette was still going strong after 14,000km of commuting. Every couple of months I would remove the cassette from the wheel and give the whole thing a good clean so that it was all shiny again, along with the chain (more often if it has been raining). I only swapped the cassette recently because my bike got a warranty exchange and therefore I had new chainrings, new chain, so I figured now was as good a time as any to replace the cassette. I just grabbed my spare cassette out of the drawer (lbs cost $170, c r c cost $58) and installed it.vinvin wrote:Hi guys,

Go to Wiggle/c r c/Ribble and buy yourself a new cassette (or two), some spare chains and the tools to install/remove them, then do it yourself. A friend of mine got caught short last week when his chain broke and he needed a new one "pronto". He ended up paying something like $70 for an Ultegra chain. All he had to do was call me and I could have given him one of my spares while he waited for a replacement to arrive. Would have saved him $40 then and there!

And I would be surprised if the cassette needed replacing after so few k's.

I may have missed it, but it's been 4 months since the last 'service' so if it wasn't lubed in that time, ridden in the rain, then the chain could be cactus. More detail from the OP is needed.
