This bike forum is really a great resource. Coming from the days before computers, there were issues and problems where I had to continually re-invent the wheel to figure out problems or answer questions. The other day I was looking for the indicator chain for Strumey Archer 3 speed hub; there are 5 sizes. I punched it in the search engine, and there was a previous answer advising the length 5 lengths of the different models (Mark l-V). I measured my indicator chain and ordered the correct part. I can't imagine how I would have found this out 30 years ago..
