LBS Just Screwed me, Right?

It's a good thing that wear is spread evenly across the cassette even if you only ride in a couple of gears!0

So if I understand correctly, if you take your bike in for "a service" there is implied permission for the lbs to do what they see fit and charge you for it.some incredulity
Who do you work for again? Surely they'd like some free advertising.0 -
Nonsense. I routinely get more than 4k miles out of a chain on my dry weather bikes, and I have yet to throw away a cassette because I left it too long. Here is said DA chain: it might be getting close to the point where I'll change it, but it's not for the bin yet:bobones 4200 miles from a DA chain with no evidence of wear disqualifies you to make statements about whether the OP has been screwed or not. There will be wear I can assure you. Also if you change the chain the new chain will skip on the old cassette. DA cassettes are expensive and worth preserving.
I log my gear mileage on Strava, and looking back I have a couple of KMC X10-SLs that were near 5k miles before getting retired. Winter bike is a different story, granted, but I cannot see any circumstances where an 8 speed chain and cassette would need replaced after 650 miles due to wear.0 -
I can assure you that it is 650 odd miles plus to the bank when a cheque turns up in the post (I work from home). You can see my Strava if you fancy, I do 9-14 mile rides which is nothing compared to most "cyclists". Tomorrow, I have a 32 miler! That will be my furthest to date! And was the main reason I went to the LBS - I'd do it myself, but didn't want to screw anything up with this charity ride coming up.
Anyway, I made the post because I walked in and said the shifter was ratlting, the response was; there's a nut inside that can come loose we'll look at it, your gear cable is shredded (it wasn't at all), you need a new chain and a whole new "block" (cassette)". THEN the chain measure tool came out. So given the initial interaction, plus the bike being such low mileage and well maintained plus the chain being given back but the old cassette had disappeared in the skip.... I don't think it's much of a fantasy to think I might have been taken advantage of. Just because the bike came back working, doesn't mean someone hasn't been screwed right! As I'm sure you'd agree, on the whole, a service takes place first to evaluate what parts do need a attention.
That said, during this time, I've learnt about chain measure tools and stretch percentages (and bought a tool), I've learnt how to change a cassette myself. Learnt about how inexpensive cassettes actually are and how they wear in conjunction with the chain - and how a worn chain impacts a cassette and crank. So all in all, I'm happy, better off knowledge wise and the work wasn't too much. I just really wish I had the old cassette so that I could see myself the difference and understand the wear and tear and you guys could have a look if you wanted.0 -
Reference the chain measure tool though - why is "not fitting in" correct?
Does that seem a little backwards to anyone else? Surely you'd expect it to fall into the gap if it was correct and not if it was too long/short?0 -
The tool measures the space between links. As it is generally recommended to change a chain when it has worn enough to measure 0.75 "stretch" the minimum length the tool measures is 0.75. If the chain hasn't worn that much yet the tool wont fit and so is fine to still use. If the tool just fits on 0.75 then the chain has worn that much and you should consider changing it. If it fits loosely on 0.75 you can try the 1.0 measurement to see if has worn even more to reach that state.Reference the chain measure tool though - why is "not fitting in" correct?

If the chains isn't worn enough the tool won't fit and therefore the chain is OK.0 -

It's the outer edge of the non-hooked leg that provides the measurement, the inner edge doesn't get anywhere near the chain roller.0 -
