How tight should a fixed gear bike chain be?

How tight should a bike chain be on a fixed gear bike?

It should be tight as it can be without binding. If the chain is too loose, it can fall off, which is quite dangerous on a fixed gear. Set the rear axle so that the chain pulls taut at the tightest part of the cranks’ rotation. One at a time, loosen up each of the stack bolts, and tighten it back just finger tight.

How tight should my chain tension be?

The rule of the thumb says that the exact tightness of a chain will only let you move for about half an inch. Now, if the chain is too loose, then you need to tighten it. If you cannot even move the chain, then it is too tight, and it needs to be loosened.

How much slack is in a fixie chain?

Typical tension on a fixie or single speed is roughly 1/4″ to 1/2″, or 5-10 millimeters, when pressing on the chain from the top, and from one side.

Can single speed chain be too tight?

Yes, absolutely. Too tight will cause extra drag, and increase wear on chain, ring and cog.

Why does my fixie make noise?

2 possibilities: the chain is either too tight or your chain line is not straight. The chain should be taut, and you need to make sure the chain ring (in the front) is perfectly in line with the cog (in the back).

How do I know if my chain is too loose?

To find out whether your chain is too long take a look at it from the side with your eyes being level with the chain. A loose chain will sag close to or below the chainstays as the chain hangs between the rear cogs and chainring. The chain might skip as you pedal, or even drop off the gears.

What happens if bike chain is tight?

When a motorcycle chain is too tight, it’ll put stress on several components of the bike and cause the sprockets to wear faster, make the engine work harder, and cause the suspension to be tight and uncomfortable. Ultimately, a tight chain on a motorcycle may break leaving you with no power.

How do I know if my bike chain is too short?

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 do you tension a chain?

To adjust chain tension, loosen the bolts that fasten the motor base to mounting angles on both sides. Tighten take-up bolts until desired chain tension is reached. Do not over-tighten. A good rule of thumb is 1/4″ deflection in the chain between the sprockets.

How tight should a mountain bike chain be?

It should be tight enough that it can move around half an inch upward and downward. But sometimes your chain still slacks, even if you already tightened it. This happens if the chain has expanded. This is normal because the chain links can stretch, especially if it’s used too much.
