The recommended gear for uphill cycling on a 21-speed is to use a lower gear to maintain a comfortable cadence and prevent excessive strain on your muscles.

If the chain is still holding together, you may need to introduce a break in the chain so that it's easier to remove.

Look for places where the chain has become jammed against the frame—these jams must be addressed before the bike can be ridden again. He had a five-year stint at Cycling Weekly and has also written for titles including CyclingNews, Cyclist and BikePerfect, as well as being a regular contributor to BikeRadar. For example, SRAM Eagle 12-speed chains can’t be used with 12-speed road rear derailleurs and vice versa. 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. This will help you maintain a steady pace and avoid sudden changes that may lead to gear slippage or damage.The easiest way to repair a loose chain, in this case, is to hook the chain onto the rear sprocket, hook as much of the chain as you can on the bottom of the front sprocket, and carefully turn the pedal backward.

You need to move it to the point where the chain can move freely into the largest sprocket, but can go no further than that. This means it can handle tough terrain and steep hills at a slower pace and help you climb steep routes with less effort and ride faster. A chain is designed to mesh with the chainrings and cassette on the bike’s drivetrain, to transfer your power through the pedals into forward propulsion.

It has specific design features to promote faster shifting to align with the shifting ramps on the cassette. Make sure the pin protrudes an equal distance from each side of the link, as even a minor misalignment can cause structural weakness in the chain, potentially leading to another repair.

Make sure the chain is tight and properly threaded through the rear derailleur and onto the sprocket, then pull it through to give yourself some slack at the lead end of the chain. 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. When you sit on the bike and look down at the drivetrain from above (see diagram below), you can see how all of these pieces work with each other more clearly: by moving the chain across to connect any two cogs, different gear combinations are chosen. You can switch between these chainrings using the front derailleur, which allows for even more gear ratio options. High gear on a 21-speed bike refers to the largest chainring in the front and the smallest cog in the back.Although the teeth of sprockets have a similar 1 ½ inch design, you still can’t use one bike chain as a replacement for any other chain. Thread the lead end of your chain through this front derailleur, turning the rear wheel to give yourself more slack as needed. 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. And there’s really no need to use either of these gears because you have nineteen others to choose from that will all make your chain happier!
