I have a 1984 Stumpjumper Sport which I'd like to convert to 1x11. I am a bike maintenance neophyte and I'm trying to get my arms around what is involved.
The bike currently has the stock 3x5 setup: 46/36/26t in front and 13-30t out back. This setup gives me a high gear ratio of 46/13=3.54 and a low of 26/30=0.87. A 1x11 with a 36 tooth chainring and 10-42t cassette gives a high gear ratio of 36/10=3.6 and a low of 36/42=0.86. So it looks like the range I'd get is about the same as what I have. Am I understanding the gearing properly?
I believe I will need new wheels (with freehub rather than freewheel), shifter, narrow-wide chainring, chain, rear clutch derailleur, and 10 or 11 cog cassette. Will I need new cranks? Bottom bracket?
I'm hoping to source some of the parts from eBay or craigslist. For example, there are lots of wheelsets online. Are wheelsets interchangeable, or do I need to take certain things into account for compatibility with the rest of the drivetrain? In general, what do I need to be aware of when looking for parts given that I have an older bike? What would be the methodical way to approach this?
