First let me say that I have never really cycled, I have done it a few times in a triathlon over the years but have never owned a road bike or really done any training on one. (Pardon any mistaken terminalogy, I haven't learned the lingo yet.) I was recently given a Griffen Vulcan B4C frame single-gear bike with a single front break and carbon fiber front fork. I don't remember the other parts on it off hand but from the research I did last night I should be able to get about $1500 or $2000 for it. So my questions are: 1. Should I keep it as a single gear and learn from there? 2. Should I keep all of the parts and add a multi-gear system to it? 3. Sell it and buy a new multi-geared bike for the same price? I have been trying to do research on cycling since I got the bike yesterday but thought I would ask the experts their opinions on this matter while I did my own research on it. A few other notes about me, I do live in a fairly mountainous area so there will be a lot of hills around so I can see the benefits in multi gears there. Also I am fairly fit as I run in half and full marathons on a regular basis during the summer season but I know cycling uses completely different muscles and I will be starting basically from scratch when it comes to that. [Edit] Sorry just noticed that there is a forum dedicated to single speed which is where this should probably go.
