Hello. I'm a mid 40s mountain biker who enjoys tinkering with bikes as much as riding them. Searching for information on freewheels led me here, so I thought I'd join. I love mountain biking but would love to do some road riding some day - just can't afford multiple bikes right now! I recently built up a bike for my wife and am restoring/overhauling my old '87 Stumpjumper right now (hence the freewheel issues). I Look forward to discussing biking with you all.
