What is a MTB chain guide?
Mounting a chain guide on your mountain bike gives you an extra sense of security, hopefully ensuring that you won’t ever drop your chain. … The bash guard lives right on the backside of the chain ring and is there to protect both the chain and chain ring from potential strikes to the bottom of the bike.
What is the purpose of a chain guide?
Chain guides are typically used in conjunction with a bash guard, an alloy or polycarbonate plate that is fitted to the chainset in place of the largest chainring and which prevents rocks, logs and other trail or racetrack obstacles from damaging chainrings.
What is the chainstay on a mountain bike?
3. Chainstay length. Or, more accurately, the rear centre. This is the horizontal measurement between the centre of the rear wheel and the centre of the BB.
How do you find out what bike chain you need?
It is possible to determine chain length from industrial drive train equations, and then cut the chain before installing it on the bike. Begin by counting the number of teeth on the largest front sprocket and largest rear. These numbers are often printed right on the sprockets and cogs.
Do I need a chain guide for a 1×10?
If you run without a guide you are guaranteed to drop the chain unless you ride somewhere with no bumps. If you run a top-only guide you may find that you lose the chain from the bottom if you back-pedal (for pedal position adjustment, for example) on rough ground.
How do you stop a chain from hitting a frame?
basically, protect the chain stays with something that will absorb the noise and call it done. The only thing you can really do is wrap an old (not too old) tube around the chain stay covering the area the chain hits or prefferably the whole thing. Then tape or zip tie it on.

How does bottom bracket height affect handling?
The higher the bottom-bracket height, the higher the centre of mass of the rider, and so the more the bike tends to pitch when faced with bumps, hard braking or steep gradients. In this sense, a lower bottom bracket improves stability in much the same way as a longer wheelbase.
What is chain stay length?
Chain stay length is the distance from the center of the bottom bracket to the center of the rear axle.
How do I know my chain size?
How to Tell What Size Chain You Have
- The distance from the center of one pin to the center of the next pin, also known as the “pitch” of the roller chain.
- The diameter and width of the roller.
- Plate thickness, determined by measuring the plates from one flat side to another.

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.
