The bike is about 15 years old. The size of tyre is probably 28.

I want to change the old chain. I am not sure which chain I can put to the bike.

Does any chain which length is enough for 28 fit my bike?

    Post more information: picture ideal, description of gears better. Does it have derailleur? In that case 3/32. If it is not using derailleur then 1/4 inch. To get the length right, compare to existing chain. Commented Jun 12, 2011 at 15:12
  • Chain length isn't particularly vital -- most chains will come with extra length and you use a chain tool to shorten it to the correct length. This is why so many wrenchers have key-chain fobs made of bits of leftover chain. Commented Jun 12, 2011 at 16:45
  • @Mathew, I suggest putting that as an answer, as I tried to come up with an answer that says much more and failed. Maybe say "BMX/singlespeed chain" as well as 1/8" (I assume 1/4 was a typo :)

    First one needs to know if this is a derailleur bike or one with a multi-speed hub. Most likely 3/32" (internal width) for derailleur (this would be called a "5-speed chain") or 1/8" (internal width) for the multi-speed hub (this would be a "fixed gear" chain). Commented Jul 19, 2011 at 11:17
  • My first thought is that, if this bike has a front derailer, it'd use the same size chains the old 10-speeds used. But aside from that, I've got nothin'. An interesting question. Commented Jul 19, 2011 at 19:49

To directly answer your question, no, any chain which is long enough is not compatible with your bike. No one here can tell you what chain will fit without a lot more detail in your question, but this is a good place to start. Daniel posted that link as a comment on my earlier answer.

Ask your LBS. They will know once they see the bike. Or measure the width of the outside chain plates with a vernier caliper on the old chain.
