Apr 14, 2016 · Modern chains all have 1/2" pitch (distance between rollers), but there are several different widths. 1/8" is common for single speed and internal gear hubs, while 3/32" (and narrower in the case of are common for derailleur-based bicycles) though many single speed/internal gear hubs use a 3/32" chain (this depends on which cog+chainring combo is used).

Feb 26, 2011 · When you buy a new chain, tell the bike store guy (BSG) that you need a chain for X speed where X is the number of gears. If you buy online, the description of the item will specify this number. The size of the links (in mm or inches) is irrelevant if you get the number of gears right. The brand will probably be printed on the chain links.

However, if you ride 1 km on a cassette with 0.5% worn chain, it's different than riding million kilometers on a cassette with 0.5% worn chain. Cassette wear happens due to chain wear (as measured in percent), and due to kilometers ridden. If chain wears fast, you have less kilometers ridden with that chain. So cassette can be saved.

Oct 18, 2016 · IMHO, this is one of many funny bicycle parts "lawyer notes". Most chain link can sustain few protrusion. Yes, pin holes will wear off and the plate will brake if pin protrusion are press too many time, only with improper tools abuse(e.g plier, hammer,etc). That's why the "don't do it" come into the picture. –

The old chain was a Shimano 9 speed that I installed 18 months and about 5000 miles ago. It had stretched modestly and was full of winter cruft/grime. The new chain is a SRAM 9 speed, my first time using the gold snap ring system. I followed instructions and made sure I have the same link count as the chain that came off the bike.

Aug 18, 2016 · (It might make sense to just get a new chain given relative prices, but I'd rather keep the chain I have because this is my knock-around bike and I don't want it to look new, I want it to look not worth stealing.) Looking at the chain, it says KMC, NARROW, with a stylized Z. The bike is a 3x7 department store bike. The rear cogs say Shimano MF ...

Mar 6, 2019 · 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.

Nov 30, 2017 · Time consuming to prepare a chain for first waxing (ALL LUBE must be removed). This step is critical and time consuming (see below). Chain runs a bit nosier, especially if cross chaining. Chain must be removed from the bike to re-wax; More paraphernalia required (e.g., slow cooker, wax, gloves, solvents, jars) You need to be organized.

@mgb: "114 pins (56 links)" is a rather strange way to put it. Firstly, to avoid unnecessary confusuion, the accepted commercial nomenclature for such bicycle chain is "114 links". Secondly, a 114 link chain will indeed have 114 pins and will include 57 link pairs (inner+outer plate). Each pair contrubutes 1" of chain length.

Commuting in a reasonably clean city should not cause your chain to get too dirty that fast. Consider using a thiner oil or even a dry lube on your chain so dirt doesn´t stick that much to it. You won't have to clean it so frequently. And less dirt and grime stuck on chain's lube means less grinding wear. –
