I don't have a chain wear tool ....... So in the absence of one - what are the signs of a chain being worn???

How long should a chain last ? This one has done approx 1500 miles. Regularly cleaned and lubricated. Mixture of road / off road use

    How long is a piece of string.

    Conditions have a big effect. Get a inch rule and measure 12 full links. It's 12 inch.

    it depends.. some people change them regular to spread wear out.. personally i run them till i'm ready for a change..

    roadbike chain been on around 5 years must of done well over 3500 miles. still works fine.
    hardtail chain was 3 year old still worked fine when i changed the drivetrain only reason i changed it was becaise i got an xtr set up for xmass off my mum and dad.
    fs dh bike 3 year old still worked fine
    fs bike just over 12 months but it was a new build last year.. the old full susser drivetrain was almost 3 year old...

    i leave the chain cassette and chainrings till i ready to change.. i tend to change bikes every 3 year anyway.. unless i break sometinh then it will get replaced...

    Depends on what conditions you ride in. 10 rainy miles in gritty mud can do as much damage as 100 miles in the dry. On the full suss I am doing well if I get 6 months out of a chain and cassette. On the single speed hardtail the chain and cogs look brand new after 2 years because it does mostly road, towpath and cyclepath mileage. Same with brake pads 2 or 3 months at best out of sintered on the full suss, same pads on the HT 2 years old and barely worn.

    3 months if im lucky, if you run a chain beyond 75% wear or 1/16 inch a new chain will probably slip on your cassette

    At least a year in any conditions

    It can do. Stomp only up hill for the same mileage as on the flat and it will. So many factors to it.

    I have absolutely no idea how far I ride. And no interest in working it out.

    ... while I have a GPS thing in my pack which tells me where I've been - even if I have no idea where I am. Then Strava adds it all up for me. So 1,500 miles on my first chain.

    Just out of intrest, what makes you change it after 1500 miles

    My gears started slipping, and I could no longer adjust them to correct it... so I assumed I needed a new chain. The new chain sorted it. I'll probably now invest in a chain checker as a worn cassette would be a lot more expensive... so far I'm still on the original.

    Park tools Chain checker - for less than £8 you will know whats what and when it needs changing, the tool won't wear out but if your chain does and subsequently eats your cassette and Chain ring it will cost you a lot more than the £8 to buy one of these. Prevention is better than cure.

    I do wonder if Park Tools have a deal with the chain/cassette manufacturers though as they've tweaked the tool and it now indicates you should replace the chain at .5% and chain+cassette at .75%, whereas it was .75% and 1%. Hmm.

    I will say though, 1% was correct for both chain & cassette. I replaced just chain, and it slipped badly (wasn't actually slipping before changing the chain, just slack). An 'expert' said cassette, I had doubts, but changed the cassette and bingo, all fine.

    Entirely depends on conditions. I've had a driterain last about 3 years, and I've had a drivetrain last about 3 months.

    My commuter gets ridden quite hard, gets salty, but little grit, the first chain which was second hand when I fitted it, lasted just over 2000miles, it was still under 0.75% but the salt had taken it's toll on the side plates and they looked aweful and so I changed it (for another second hand one!).
