Please do not publish crap advice for Joe Public. Plugs are fitted to all electrical goods these days, in the days they weren't....... It’s not something that can be done with a drivetrain with multiple chainrings, because the position in which the chain will land when shifted between chainrings can’t be determined, so the teeth in double and triple chainrings all have the same width, designed to mesh with the narrower inner-chain link. While we will walk you through some of the most basic steps for sizing and tightening a new bike chain, it's always a good idea to watch some of the great videos that are available online. This creates a diagonal line that causes the chain to rub against the front derailleur cage or the rear derailleur.

While you can tighten a bike chain on your own, it may be easier if someone else can give you a hand. If the chain keeps falling off or can't hold the tension, it's time to think about getting a new chain. When To Replace Your Bike ChainToo long chain will increase risk of chain dropping, while too short chainputs too much stress on the drivetrain, or can damage it, if it can be put and closed over the chainrings in the first place.Chain that is too short can also damage rear derailleur. With either style of gear shifter, the left will control the front derailleur and the right controls the rear derailleur. You can positively identify your bike chain but do you understand its function? The chain on your bicycle, which is a roller chain, is responsible for transferring the power from your pedals to the wheel of your bike. Thanks to the bike chain, the harder you pedal, the faster your bike goes. A Closer Look At The Parts On a mountain bike or a hybrid bike, the shifters are easy to identify (they’re simply near the brake levers if you’re wondering!) It’s recommended to use only one or two gears at a time to prevent cross-chaining and protect the chain and drivetrain.

Different bike manufacturers and models may have varying gear ratios and combinations, so make sure to read the user manual or consult a bike mechanic to determine the appropriate gear combinations for your bike. 21-Speed Bike Gear Maintenance Tips Hope that you have understood the importance and difference of different sized bike chain and bike chain length. For a smooth and comfortable ride, you need to go for the best chain size for your bike. A new bicycle chain usually comes with 116 links. This is long enough for the biggestchainrings and for most distances of rear wheel from front chainrings. So for optimal length a newchain is usually shortened from the 116 links that come in the box. In rare occasions – touring frames for example, with extremely long chainstays, 116 links might not be long enough, so a few links off another new chain need to be added to reach optimal chain length.

Instead, you get three cogs (which are called “chain rings”) near the pedals at the front of the drivetrain*. At the rear wheel hub, there are seven additional cogs (which together are known as a “cassette”). On road bikes, the gear shifters are incorporated into the brake levers. Often these will operate be pushing the brake lever to one side to shift one way and pushing a separate button or lever to shift the other way.

Either go with a chain that is a bit too short and avoid shifting to the big-big combo (to avoid damaging the RD). there is some variance between chainsets from different manufacturers, so it is advised to get a chain from the manufacturer of your bike’s chainset Anyhow, this equation is not applicable for bikes with extreme variation in chainring sizes or short chainstays. In such cases, you need to use a complex and rigorous equation which is:It’s a little easier with electric bikes, fitness bikes, city bikes, hybrids and MTBs as the gear shifters are normally separate to the brake levers (although generally they’ll be positioned next to the brakes). Each gear shifter will comprise two levers – push one to change up a gear and the other to change down. Even the phrase “21 speed” is a little deceptive. To be more accurate, for each “speed,” you could pedal along at the SAME miles/hour on your bike. The main difference is the width of the side plates; the rollers that run over the teeth in your cassette and chainwheel are the same 2.18mm width for chains with nine, ten or 11 speeds, although they’re a different width from the 2.38mm rollers used by chains for eight speeds and less. This will create the easiest gear at the top of the cassette, which is great for climbing hills or slow-speed riding.
