http://www.youtube.com/bikemanforu How do you know what kind of chain you need for your bike" YouTube's how-to guru of DIY bicycle repair shows you in this tutorial. Free Shipping http://www.bikemanforu.com on bike parts, tires, tools, and cycle accessories. "Sticks and stones will break my bones but chains and freewheels excite me," BikemanforU says. This instructional video shows how to spot the important difference between freewheel and cassettes and demystifies what 1/2 x 1/8 or 3 x 3/32 really mean when it comes to sizing up your chain. He uses a vernier caliper to show how to measure center of the pin/ "Center to center of the pin to get a half inch," he explains. "Now, what's the difference between an eighth and three thirty seconds? How many three thirty seconds is an eighth of inch? Four is the answer. So there's only one thirty second of an inch difference between the two." Using a micrometer, he shows us the distance/difference, then shows how to measure the micro difference in thickness between the link. So now, that's what we had way back when. Enjoy a quick mid-century history lesson on bicycle chain, too. "Back in the day that's all there were," he says. "Now, here comes 12 speed bicycles, which means six speeds in the back. Then mountain bikes come along, well basically, a mountain bike was one of those old school Schwinn middleweights with some gears and stuff. They were cruising down the mountain on coaster brakes, drifting on the side of the mountain. Then comes 10 speeds on the back, and I think Campagnolo even has 11 speeds in the back. What's the difference between a freewheel and a cassette? If you still can't figure it out, check out this video. Anyway the distance on a wheel hub is the dish, the flatness. "These spokes can only get so flat. Now you've got to get 10 speeds in the same amount of distance. So the chains had to get skinnier. The sprockets in the back had to get closer and closer and closer." He shows the quarter-inch difference on a micrometer. Chains got skinnier and skinnier and skinnier. That is the story behind the chain. Now there's multitudes of new chains out there. You can cheat a little bit. Shiano, 6 7 or 8 speed. We do a specific 7 speed chain Z7, also good for 18, 21, and 24 speed bikes. We also do a little fatter 18-speed chain, which is a six speed chain (with a triple crank). The tutorial covers 5, 6, 7, 8, 9, and 10 speed chains. If you're not sure what you need for your mountain bike, cruiser, hybrid or road bike, BikemanforU has a recommendation. "Bottom line is however many sprockets you have in the back get the right amount of chain in the back. If you're doing Campagnolo, I strongly recommend you stick with Campagnolo. Shimano? I have no problem using the KMC chains with Shimano stuff. Campy is its own little deal...Campy is Campy. Let the Italians be."

Will a 10 speed chain work on a 9 speed casette?
-
Thanks man! So now I know I don't need a bike multi tool for 11 speed chain
-
Bike man only 3 speeds are actually used the rest are to attract ladies
-
Best explanation on chains Ive heard to date. Cheers, BikeMan
-
1/8" 3/32"....haven't you yanks ever heard of the metric system ? step into the 21st century for Christ's sake.
-
so an 8 ring cassette with three rings on the cranks is still an 8 speed?..my current chain has 111 links not including the master link so i'm not sure which chain to get.. thanks for any info on this
-
Very interesting, thanks bikeman
-
You sound like you enjoy bikes a little too much :) lol
-
where is the 11 speed!!!???:D
-
Nice! and I can also recommend this https://plus.google.com/108959741808482293517/posts/XHxwvEZHXJC

use the metric sistem come on we are in 21st centrury.

Hi Bikeman, just wondering if a 9 speed chain would work on an 8 speed crankset? I have a 9 speed cassette and everything else apart from crankset
-
I understand most of this but if I search for a replacement KMC 6 speed chain I find dozens with different codes all showing virtually identical specifications. What the hell is the difference between them? Do the different "Z" numeric codes mean anything at all?
-
Hi Mr Bikeman: after changing my chain, at the 0.75 % wear indicator; the new chain jumps over the teeth from the cassette when under load, i believe this is called chain slip.
This happened to me before; i decided to change the casette too and ofcourse the problem was fixed.
However, I now have the same problem after changing the 3 month old chain at 0.75% running the new one on the 3 month old cassette.
How is this possible? Should I replace at 0.5% instead?
What are your thoughts on never replacing until problems arise? -
Hi, hows things? I have a bit of a project ahead of me. I have just bought a panasonic 350W mid drive hub motor. I am going to modify a frame to fit it.
It takes a 1/2 x 1/8 chain (BMX size chain).
But i would like to use a rear cassette and derailleur setup. (internal hub would be nice but heavy and expensive)
Can i use a rear cassette and derailleur with my 1/2 x 1/8 chain? Thanks -
Related to my previous comment, another idea I had is to make the 5 cogs in the rear very close ratio thus when you shift between the front 3 chainrings, you get 15 progressive gears. For example, if the rear had 28,26,24,22, and 20 and the front had 20,30,45, then you could shift all 5 cogs first on the small chainring, then all 5 on the middle chainring, then all 5 on the large chainring and you could then have 15 progressive gears. Sounds like fun to me.
-
Also what do you think of this idea Bikeman? Someone that has a 3x7 for example but wants progressive gears can do it by skipping the middle chainring completely and having a cassette or freewheel that spans about a 2x in ratios (such as 28-14). For example, on my mountain bike I have 28-14 with 24,34,and 42 in the front. If you number the front chainrings 1,2,3 from smallest to largest and number the rear cogs 1 thru 7 from largest to smallest, what I can do is shift from 1,1 thru 1,7 (24/14 = 1.71) then immediately go to 3,2 (42/24 = 1.75). The intermediate (middle) chainring acts as a "ramp" to get the chain from the small to large chainring (or vice versa). So my 3x7 then effectively becomes a progressive 13 speed without having to do any fancy shifting since it is very easy to go from the small to large chainring (full stop to full stop on my twist shifter). Going from 1,7 to 3,2 is only slightly tricky cuz I usually shift to 3,1 first cuz it is easy and then do a quick "correction" to 3,2. Note that even a cheap $100 Walmart mountain bike can do this fairly well and has more progressive gears when shifted this way (13) than even an expensive 1x11 setup. One thing I do is shift both the front and rear derailleurs simultaneously but I was told it is not a good idea to do that but so far it has been successful everytime I tried so what is your advice on that sir?

Hi Mr. Bikeman. I have a 21 speed (3x7) freewheel mountain bike that I would like to convert to 24 speed (3x8). Reason is I would like 34-28-24 as my 3 largest cogs but my current 7 speed freewheel has 28-24-22. I considered at the Shimano MegaRange 7 speed freewheel but that is 34-24-22... so it appears I have to go to an 8 speed to get what I want. The rear dropouts are spaced 135mm on my mountain bike so I am assuming that is adequate. So can I make this work? I assume I need nothing more than the 8 speed freewheel, an 8 speed rear derailleur, and 8 speed index shifter. I also assume I do NOT need a new chain nor a different front derailleur. You can assume I will not use the new 34 cog with the largest chainring in the front so that is why I say I don't think I will need a new chain cuz I am not really adding teeth since with the largest front chainring (42 teeth), the largest rear cog I will ever use on either the 7 or 8 speed is the 28 tooth.
Thank you. -
lol thank you, i was ignorant of this!

Is it possible to use a 8 speed drive train with just an upgrade of 10 speed crankset? Assuming all are Shimano stuff.
