2011年2月26日 · 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.

2017年11月30日 · 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.

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.

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.

2016年4月14日 · 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 …

2011年6月18日 · The proper design performance will be obtained when the CN-7900 is installed so that it faces the correct way. If it is installed so that it faces the opposite way, the chain may come off and the bicycle may fall over and serious injury may occur as a result." –

Third the chain gets washed in 91% rubbing alcohol--this is primarily to wash off the degreaser, but it also gets the last of the grime. Sometimes this takes two rounds--the last round of alcohol should remain quite clean. Fourth the chain is left to dry for ~5-10 minutes (just long enough for the alcohol to evaporate off).

2022年3月14日 · @rclocher3 is right, a worn out chain can kill a sprocket within a megameter. Even if the sprocket is made out of steel. Or, to put it more concisely: The chain is stronger than a single tooth, but half the teeth of a sprocket are stronger than the chain. Btw, the weakest point of a single speed sprocket is not its outer teeth, but rather its ...

2012年8月26日 · Snap the removed links back onto the chain and place the chain back onto the breaker with the pin facing into the breaker like this: Carefully push the pin back into the link making sure the breaker pin and the roller pin are aligned. Misalignment can cause damage to the chain and breaker.

2011年11月3日 · A road chain is good for ~3000 km / 2000 miles before it starts wearing into the cassette, whereas most chainrings are good for "the life of the bike" or 20,000 km. A worn cassette and worn chain can do more than 3000 km, but they need replacing together. MTBs off road will wear quicker.
