Changing cassette, chain etc...yet another thread

[nickyboy]

Hi
Last winter I needed to change my cassette and chain. LBS looked for a shimano but couldn't get (this is 8 speed 11-28) so recommended a generic Taiwanese one

Since then I've done about 2,500 miles. I clean the cassette and chain every 2-3 rides and have mudguards to keep the worst off the drivetrain. I live in a very hilly area of the Peak District so the miles I do are very hard and this presumable puts more stress on the bike components

My chain snapped last week so I got a new one fitted. Now it is jumping and, upon inspection, I can see that my "popular" gears 3,4,5 the teeth are well worn.

Question is; given the mileage and the very hilly nature of the rides, do you think 2,500 miles is low for a new cassette? I'm going to have to replace it, the only question is should I have bought a more expensive one? Whilst it is a generic Taiwanese one, I presume all lower to milddle end components are Taiwanese/Chinese in any case

I would be happy with 2500 miles on a cheap one.

Edit: I just read that again. if you clean the chain every two or three rides that may not be good wear. That is a lot of chain cleaning. I don't know but I would ask in the know how section.

2,500 miles isn't awful.

I buy 105 components and look for decent discounts online

^^^^ This. I only get that sort of distance (maybe 3-3.5k if lucky) using 'quality' Sram PG950 or Shimano Tiagra cassettes with a chain swap part way. If you have run one chain and cassette for that distance then I reckon you have had your moneys worth

Thanks guys. I reckon it was you, Skol, forcing me to chase you up the Snake that finally did for the components. At least the chain snap was only 2 miles from home

That's good mileage IMO if you want more mileage on a cassette change the chain more often. For the moment dont ride with the new chain slipping otherwise you will need a new chain and cassette!

It doesn't matter where it happens, we fix and continue

Just clocked up 2500 miles on my Forme and I think the cassette still looks ok. Bike shop was happy enough to just change the chain at the service a few weeks ago. Pretty sure I should get at least another 1000 miles.

If you changed the chain a few weeks ago and haven't had any trouble with jumping/skipping gears then it sounds like you are fine to continue. IME when a new chain is fitted to an old cassette you know within a mile or two if all is well or not.

Charlesworth....so pushed it up the hill and freewheeled it back into Simmondley. Then got the LBS to deal with it

I got about 4,000+ plus on a mix of 7 and 8 sp cogs on my 7 sp, some from a Hg50 road cassette and some from a HG41, just got a 12-25 HG50 8sp from Wiggle and using the cogs with 7sp spacers on my 7sp.

I do clean it often, and every time its been wet. Chain is KMZ 8sp about £8
I hope to get 4-5000 miles out of these.

I reckon on about 3 to 4,000 miles from a Shimano HG50 8 speed cassette or SRAM equivalent. During that time I get through 2 or 3 chains.

I change chains when a wear gauge indicates just below 1% stretch. I haven't had a chain snap since I started doing that, which I think is close on 20 years.

I keep a spare chain and cassette all the time, Only takes about 10 minutes for either or 15 for both once you get confident, so if you're happy with DIY servicing it's worth doing.

How much mileage could you expect out of a shimano 105 10 speed cassette and chain? I push pretty hard on it. Also how do you tell if a chain is on its last legs without it snapping on you?

Use a chain-checker. Wear rates depend on riding style and conditions. An all-weather commuter could easily see the chain worn out in less than 1000 miles.

Wow that is really crap! On my motorbike a chain+sprockets typically lasts between 15000-20000 miles. I know the chains are obviously stronger, but the bike is capeable of 150+mph, weighs 240kg and has a 0-60mph of about 4 seconds. And I often use the power too. I was expecting something like 5000 miles at least for a cycle chain tbh.
