What size chain does a BMX bike need?
BMX chain sizing The majority of BMX chains – both traditional and half-link – are the standard 1/8” width. Narrower 3/32” chains are available for weight-shaving racers, as are more heavy-duty 3/16” chains, but for most riders the standard is fine.
When should I tighten my bike chain?
Check your chain out. It should be tight enough that it only allows you to move it up and down about one inch. If it is sagging or much looser than that, you need to tighten that chain up. Chains often loosen when a bike does not have a derailleur.
Why does my BMX chain keep falling off?
If your wheel isn’t super tight then a session of peg riding will nearly always result in your wheel moving about and your chain becoming super loose. The rough bashes that your wheel, axle and peg receive when grinding can easily push your wheel forward or over to one side.
Why does my BMX chain keep coming loose?
You will be stressing your rear triangle and putting load on it that can cause a loose or super tight chain. I usually pull my wheel back and then making sure the wheel is kicked a little to the non drive side.
How do I know my bike chain size?
Add the multiplied chainstay length, the divided number of teeth for the chainring and rear sprocket, and add 1 (or 2.5 cm). The result is the ideal chain length for your bike. For example, you’d add 32.5, 13, 7 and 1 to get 53.5. The length of the chain should be 53.5 inches or 135.89 cm.
Can I shorten my bike chain?
Conclusion. Bike chains can lengthen due to age and use, or you may buy one that’s too long. With a few tools, a bike stand and a little time you can remove extra links, shorten the chain and make your bike rideable once again.
