Product Information

Lastly, the crankset is the set of gears that attach to the pedals. A typical 21-speed bike will have three chainrings on the crankset, with the smaller one for easier gears and the larger one for harder gears. High-pivot mountain bikes are an exception, though, which typically require a longer chain length, and you may find you need to buy two chains.

Another recently added complication is that Shimano has introduced Linkglide as an option for its groupsets with 11 speeds and fewer. This runs alongside its higher performance Hyperglide cassette configuration and uses a Linkglide chain with a different profile to the Hyperglide chain. Shimano is looked to rationalise its lower spec groupsets with the launch of CUES, which offers cross-compatible Linkglide parts across its lower spec groupsets. There may be a small metal "tab" between the 2 small pulleys in your derailleur. The chain must pass this tab without rubbing on it.The design of a chain’s outer side plates varies significantly between makes and chain models. Often, there’s some sort of ramping designed to help shifting, while more expensive chains will often have chamfered edges to the side plates rather than flat sides. For mountain bikes, it has different gear systems. In that case, you have to look forward to having the best chain size. For 9-speed, 10-speed or up to 12-speed you are going to have the variation of gearing system.

Here’s the thing, with fewer gears you end up using all the ones available, and each gear offers a slightly different cadence. 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”). This creates a diagonal line that causes the chain to rub against the front derailleur cage or the rear derailleur. Having your front chainrings too far out or too close inwards can prevent the FD from shifting onto a chainring.To replace a chain, you’ll usually need a chain tool that is compatible with your manufacturer of chain to push out a chain rivet and remove your old chain. 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. 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. 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!)

Each link has two side plates, which are held together by rivets (also called pins) and a roller sits on the shoulder of the outer link. In some chains, there can be a separate bushing on either side of the roller, although these are usually absent from modern chains. Before knowing about bike chain size you should know why you should choose the perfect bike chain size. To gain stability and suitability there is no option other than choosing the best bike chain size. 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.Others prefer leaving the chain with the “safe” length, and put up with a bit more chain bounce on bumpy roads, and more noise if they shift into small-small combo. This is less problematic than using a chain that is too short – it won’t damage the RD (unless you ride for miles like that).

This will mean that you won’t have to push the pedals so hard as you climb hills, though you’ll find that your legs will be turning the pedals faster.

So, you will get different speeds from the same bike by giving the same amount of pressure on the paddles. Which Chain Size to Choose Small front / middle rear = gear 4 (nearly the lowest gear) = you’ll more easily be able to cycle up hills, though you might find your pedals spinning too fast on the flat First, take off the old bike chain. After that, switch the derailleurs with respect to the biggest and littlest chainrings. The one in front goes to the former and the one behind the latter. 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. If you are using a bike with a derailleur the number of cogs on the rear hub will determine the chain size you will need. They are always 3/32" chains.
