In this case am I right in thinking that my initial calculation would be (36-9) + (38-28) = 27 + 10 = 37? If so, How have you any idea how short I would cut the chain? 116 links (148cms) is what most chain length calculators advise for a 38T.

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: Insert the new chain– Now you have to insert the new chain by following the same process. You should open the certain chain-link first and after setting the length chain you will join the chain link. For example, SRAM Eagle 12-speed chains can’t be used with 12-speed road rear derailleurs and vice versa. While you can mix some 11-speed Shimano and SRAM components, it often makes for a noisier drivetrain.

The key components of a 21-speed bike are the derailleur, cassette, chain, shifters, and crankset. Derailleur

There are two kinds of chain links found in a bike chain. One is SRAM and the other one is CONNEX. SRAM chain link has a flat hole before the chain joining and CONNEX has a slightly downward chain hole. Changing Time for Old Bike Chain For road bikes though, it’s a little different: the gears are not controlled by separate shifters; they are actually built into the brake levers. Shimano also makes a Linkglide chain that is designed for use with electric bikes with 10 or 11 speeds, although it can be used with its Hyperglide drivetrains as well as the ebike-specific Linkglide. This has a different link shape, designed to handle the extra power provided by the electric motor.If you have a standard chain, you'll want to use a chain tool to break the chain. This is done by aligning the pin of the chain tool with a pin in the chain and turning until the pin moves. Again, taking a look at videos can help you get a better visual of this whole process.

Add one rivet with the reference rivet, and the newest one becomes their reference rivet. You’ll need this as you won’t be able to join on the earlier reference rivet. The shifters control the derailleur and allow the rider to shift gears while riding. Most 21-speed bikes use trigger shifters, which are mounted on the handlebars and operate with the rider’s fingers. That way, the chain will not slap as much, will be held tighter, but if you shift into big-big by mistake, you risk damaging at least the RD (possibly hanger as well). Shift gears before you need to– To ensure smooth gear changes and prevent unnecessary wear and tear, it’s important to shift gears before you actually need to. 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.In these cases, you can shift to a low gear by using the left gear shifter to move the chain across to the smallest chain ring at the front, followed by changing the gear to the largest cog in the rear cassette using the right gear shifter.

While we touched briefly on the speed bike chain measurements, we’ll discuss other sizing a little more in depth. More often, cyclists like me end up with a lot of options in hand. We even turn confused about what to choose. So, for helping in properly selecting bike chains, I am sharing a bike chain size chart below. With either style of gear shifter, the left will control the front derailleur and the right controls the rear derailleur.It is often asked: what is the optimal chain length for a bicycle with derailleurs? Should a new chain be shortened and how much? That is answered in this post. For single speed bicycles (or bikes with internal gear hubs), see: Determining optimal single speed chain length.
