I just bought a used road bike. Pretty clean with very little use. I am trying to determine how old it is. It has all Shimano 105 components but the series is a bit older than I can find info on. the front derailer is FD2206 and the rear is RD1050. The brakes are SLR. The sifter has M5 light action written on it. Anyone have any idea of the age here?

If you are looking for an age, you might do better figuring out the age of the bike by colors, gruppo (105 of course) and other compontents. This will only work if the bike is mostly stock and from a non-custom source.

Just a thought

What color are the components? Are they a dark green?

It's too damn bad the bike part mfg.'s don't put patent numbers on their component parts like most other mfg.'s. This would give us some clue as to mfg. date and history of the Part as patents on an item list all the patent numbers with the latest "improvement" being last.

Have an old Wayne gas pump which last patent listed is 2,242,341 which pegs it being built between 1941 and 1942. A list of patent numbers by year are very handy dating old parts, most bike parts being the exception as they have none.
