2016年11月6日 · Bike chains come in two sizes. There's 1/8" chain for single speeds (bikes without a derailler) and 3/16" which is for geared bikes with a rear derailleur. In addition you can get master links for 6/7/8 speed, or 9 speed or 10 speed or 11 speed. So count the number of cogs in your rear cassette and go from there. Master kinks are cheap.

2019年3月6日 · Chain size is specified by pitch and width. The pitch is the distance between rollers (1/2" on all modern bicycle chain). The width is nominally the width where the sprocket teeth fit in. Bicycle chain comes in four basic widths: 3/16" (.1875", 4.76 mm), used until the middle of the 20th century on many bicycles; this was inch-pitch chain.

Next, measure the width of a link and the length. You can also measure the internal length and width, but those are less crucial and you can measure the outside and subtract the diameter to get an approximation. A helpful number to have is the number of links per foot of chain. Measure one foot of the chain with a tape, then count the links.

2011年2月26日 · Mark that link, being careful to make sure you pay attention to the outer plates, and have a set of inner plates to pin through them. Add 2 links to this marked length, to give yourself slack to adjust the chain tension, and cut the chain. Rivet the chain together using the link, pin or rivet which the brand of chain requires.

2016年4月14日 · Alternatively, take your old chain and a pair of calipers and measure the inside width between the plates of the chain and see what it comes out to. If theres a quick link in the chain, you can also note that 1/8" quick links have both pins on one plate whereas 3/32" chains have one pin on each plate.

Then pull out the chain, putting the anchor at the first mark then stretching it out straight between the marks, turning it at each mark to measure each "unit" while flaking the chain back and forth on the work surface. Make sure the chain dries completely if you’ve used it recently, then make your surface preparations.

I'm installing a Shimano 1x12 setup and following the instructions.When measuring the chain it says to put the chain around the largest sprocket and largest chainring, measure to the zero point, and add 5 links + the quick link (for a hardtail).

2022年7月6日 · I'm having trouble understanding the latest SRAM chain sizing guide. I run a 1x11 on a full suspension bike (not eagle). You can see in the image there two scenarios for chain overlap. They have the 1x11 listed on the top with the hardtail eagle. Does this mean always use +2 links overlap whether HT or FS 1x11?

For example, a master link for a 11 speed chain will be too small for a 7/8/9 speed chain. Manufacturers generally suggest you use their chain closing mechanism (Shimano's special rivets, KMC/SRAM's master links, Campagnolo's special rivet that needs peening, etc.), though many people mix and match master links across brands without issue.

The video says that you have to pass the chain for the big chainring and the big sprocket. Without going through the pulley wheels for rear derailleur. This gives the basic measure. If your bike has double or triple front chainrings, you must add a full link (internal link and external link) to basic measure (minute 1:16 in the video).
