    Park tool chain wear gauge question

    I have one of the Park tool chain checkers with .5 on one side and .75 on the other. The .5 side goes in if I give it a little push. Is that time to replace or should it fall into place?

    My CX chain has 350 miles on it (chainring has 350 and cassette has 500) so I'm a little surprised to see a Dura Ace chain remotely close to .5 at this point (being able to push it in).

    My road chain has 1400 miles on it (chainring has almost 5k and cassette has 5k) so that makes a little more sense.

    I'm aware of this method and it is 1mm elongated, but the tool is easier for me and my preferred method. If you made a thread asking how to prepare steak, telling you to prepare chicken instead isn't what you're looking for is it?

    Steak might taste good, but chicken is healthier.

    No, you're trying to figure out how worn you chain is. The correct analogy would be asking how to prepare a steak and 1 person says in a frying pan but you prefer on the grill.

    I highly doubt your chain needs replacing yet. Those 'roller wear indicators' are well known for showing new chains to be worn.

    I'm a flatlander so I spend 90% of my time in the 15, 16, 17, 19 cogs. You think 5k miles (never even ridden on wet pavement much less rain with frequent chain maintenance) might mean a shot cassette?

    You prefer a notoriously inaccurate tool...when a simple steel ruler is easily found?

    Well, good luck.

    Only if you ever put a ton more miles on a chain. If you change your chains out at 1000-1500mi you really only ever have that many miles on your cassette/chainrings. If you've done 3-4 chains at that mileage on one cassette you don't really have 4500-6000mi of wear on the cassette. You've ridden it that many miles but because the chains never have that many miles they don't impart that wear onto the cogs/rings. I'm quite sure the frequently ridden cogs have more wear than the others but I wouldn't think they'd be 'worn out' yet.

    I rode today, & I feel a 'little' "wore out". But I think my chain is OK.

    This has nothing to do with Steak vs Chicken, please stay on topic.

    I prefer a good ribeye or filet to chicken - other cuts I'll go with Chicken. When's dinner?

    How do you feel about a standing rib roast? Maybe something dry aged in the 30-45 day range?

    If beef needs to be cooked to 145f to be considered done is it done when the thermometer isn't to 145 yet? No, it's not.

    If I understand the OP correctly that's the cooking analogy you should use.

    If you wait to let if fall into place you will get more miles out of your chain.

    Actually I prefer smoked brisket, don't much care about temps, it is the time in the smoker that is important. In this analogy, if you cook by thermometer, that is just crazy.

    How about a nicely marinated skirt? Cooked correctly they're pretty tasty, and great for sammiches.

    Nobody mentioned pork chops?

    To the OP: Those Park chain wear checkers often show 0.5 when the chain is brand new! Now, repeat after me:

    Who cares? The only thing that matters is if they show the chain is worn out when it is not. Everything up to that point is academic.

    And fewer miles from your cassette and chainrings.

    It's not even to .5 yet and you're warning of cassette damage?
