FAQ: How Tight Should Your Bicycle Chain Be?

How much slack should be in a bike chain?

Chain Tension There should be approximately one half inch of movement in the chain up and down at a point half way between the front and rear sprockets. To change the tension loosen one of the axle-nuts and move the wheel forward or backward slightly and snug it up again.

Can you over tighten a bike chain?

If it moves too far in either direction it means it isn’ t tight enough and should be pushed a bit more on the tire. If it’s too tight you will not be able to turn the pedals, so it’s important to make sure that you get this step just right.

How do you know if your bike chain is too small?

You should also see two slight bends at each jockey wheel of the rear derailleur. If the chain is too short, this shift is difficult to make and the derailleur cage is stretched out and almost parallel to the chainstay. If the chain is really short, then you might not even be able to shift into the largest cog.

How tight should chain be on fixed gear?

The chain tension on a fixed gear is quite critical, and is regulated by moving the rear axle back and forth in the forkends. If the chain is too tight, the drivetrain will bind, perhaps only at one angle of the pedals (chainwheels are not usually perfectly concentric). It should be tight as it can be without binding.

Why does my bike chain slip when I pedal hard?

Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike your shift cables stretch the most. They can also stretch over time as you ride. Hippley explains, “It takes cable tension to open a derailleur, which shifts your chain between gears.

Why does my chain go slack when I stop pedaling?

If your chain is getting slack on top when you stop pedalling or backpedal, then the problem is in your freehub (or freewheel, whichever you have), a dirty freehub will cause all the problems you’ve listed, even on a brand new bike.

What happens if your bike chain is too loose?

The problem with a bike chain that is too long or is loose will cause the chain to slip off. And this will affect changing the gears cause the dérailleur does not have enough capacity to pick up the slack with the chain being too long.

Should I shorten bike chain?

1 Answer. ” Never run with a chain that is too short, except in an emergency.” (from Sheldon Brown’s Derailleur Adjustment page). If a short chain ends up on the big chainring and big sprocket at the same time, then the derailleur will probably get damaged.

When should I shorten my bike chain?

Most of the time, you will inspect your chain to know whether it needs a replacement. You should count the links from the first pin to the last pin. You must ensure that the gap between the pins corresponds to 12 inches. If it extends to more than 12 ⅛ inches, it is time to replace your bike chain or shorten the chain.

What happens if you stop pedaling on a fixed gear?

On a fixie the rear cog is joined with the rear hub, so when the wheel turns, the cog will turn too. This means that when you stop pedalling on a single speed bike, the back wheel will continue to turn but the cranks (pedal arms) will not. On a fixie if you stop pedalling the cranks will continue to spin.

Does riding a single speed make you stronger?

Only having one gear makes you a better rider in a variety of ways. The most obvious one is that it makes your legs stronger because you have to crank up hills in a much harder gear that you otherwise would. But it also makes you more efficient. Riding a singlespeed means that you need to plan ahead.
