The distance of the 1st pin to the 24th pin will never change because the plates never stretches. The rollers inside is the one that wares out. The cylindrical rollers gets thinner from constant rub from the teeth of the gears. Once worn out, the chain checker falls in between because the teeth of the checker is on a thinner rollers. One tooth the right side of one roller and the other is on the left side of the other roller.
@@sydfixesbikes thanks for responding. I like all of your videos. Including your rehabs but this one triggers me. The metal plates does not stretch. Thus the distance of the pins will not. Pitch of the rollers change. As the circumference of each rollers decreases from wear, 2 rollers with pins on the same spot, will have a lesser pitch. Roller on the left will be thinner and roller on the right will be thinner. If the plate does stretch, the chain gauge should not fit a stretched chain. But it will fit and it drops when it’s worn.
We've had this discussion with people before and looked into it too make sure we were giving accurate information. You are correct that the metal will not stretch. But the distance between the pins (not pins on the same link, but pins on adjacent links) will change over time because of wear on the pins that make the diameter of the pins smaller so adjacent links move apart. We agree that the best way to measure it is with a chain wear indicator, but not everyone has one of those and the ruler method does, in fact, work too!
First method checks wear on the roller bushings. Second method doesn’t account for roller wear and only tells you if your chain is “stretched” which isn’t how chains wear out.
You got it wrong. Both methods measure pin to inner plate wear diregarding roller size/wear. CC-3.2 from Park tool is affected by rollers and can't measure newer chains accurately. If you look closely at the one side there is a spring that pushes the roller to the left, same with the other side.
It's not suggested anymore because it is affected by roller size/wear and doesn't work on newer chains with oversized rollers. Use the newest chain checker from Park Tool or the one depicted in this video. Or a tape on a tensioned chain.
If it's just the rollers that get worn away (the plates aren't actually stretching), wouldn't this imply that 24 links will always measure 24 inches, regardless of how worn the chain is?
Basically it's the intersection between two links that wears (the roller) so when that wears, the links start having a bit of play in the intersections which allows them to pull apart slightly, this making the distance longer between the pins. Does that make sense?
You had it correct the first time. Technically chain stretch is the pitch of you chain is longer. The rollers on the interior are what changes the links on the outside do not. You chain does not get longer this is horrible information
@@daylightsensor8695 the outer plates are connected to the inner plates with the pins. The rollers rest losely on top of the inner plates. It is the first interface that gets worn and elongates the chain.
The ruler method is fine for measuring pin to link wear, but the more important measurement is to check the roller wear with the tool or use a vernier caliper gauge
@dOoMnX if you go by the pins then the drive chain will be long gone before then, the internal part of the pin which contacts the roller is the highest wear point, that's why all chain check devices measure there and not the pins on the external
@@Theclarksonmtb Not at all. You are misinformed. The rollers float on the inner plates. Whether they are oversized or shrunk due to wear it doesn't really matter as long as they always fall in the right place between the teeth. Only the wear between the pins and the inner plates can make them misaligned.
My chains have this nifty feature when they tell me when i need to replace them . SO how it works is i will be riding along and my chain will break , and that is how i know i need a new one :)

Im on a really tight budget. I will only replace my chain if I see a bump or it doesn't sit well on my chain ring. Im using my shimano hg 10 speed chain. More than 1,500 km already and its still looks fine with maintenance of course. 👍

@@ScholliUlz We (Americans) learned both during school. Math and science classes are taught using metric.

@@sydfixesbikes you would measure 20 links/40 pins for an expected length of 508 mm. If reads more than 511 mm it's more than 0.5% worn. If it reads more than 512mm it's past the 0.75% mark. 513 mm would be 1% wear.
I just used the ruler method and 12 inches covers 25 links and not 24... That's not good 🤣🤣🤣 Is the ruler method universal for all chains? Mine is really old and has been used a lot without replacement, but 25 seems like a lot.
Don't count the pins, count the links. Most likely you're counting the pins and including the one you're starting on, thus getting 25. Measure from the center of one pin, count 24 links (or pins, just not the starting one) and see if that lines up better!
So Clear.
I have heard of the ruler method and now I've seen it.
I just used it and my chain is fine, but I have a spare in waiting. :)
Thank you Syd.

The second method doesn't work. Chains don't really stretch, they just give the illusion of stretching, it's the insides that wear out.
They do measure longer as they wear out.

I did not have to do any of that. I knew its time for a new chain because I found it fly from bike and land at the crosswalk. 🤣🤣😅😅😇😇
Also Need to consider what is the speed, 9 speed or 11 speed
Real people use METRIC 👍
should the chain be on the smallest cog or the largest during the check?
Doesn't matter. Generally somewhere in the middle of the cassette is easiest

Single speed chain should be replaced as it reaches 1% stretch, or 12 1/8 inches in this example.
Never knew that tool existed
It's mountain biking, they have a tool for everything and people with a lot of expendable cash to buy niche tools😒
Yeah it's a strange take on a regular measuring tape but the unit is based on one's thumb I think?
Its just a bicycle, run that shit till it snaps. More and likely never even going to happen.
That's just wrong. In the long term it's gonna cost you even more since a bad chain will ruin your cassette.
I m in love 😍
If it breaks.. Its time. Hahahaaa
if you replace your chain with new, your cassette might not be compatible with it. it will jump to other teeth
Never replaced a chain, ever.
