Hey Supcom. I'm already dieting, losing weight. I'm down from 345 last year.
Why a fixie? Well, because I have one. And yes, its my only bike. Its my commuter, everything. I have other bikes in various stages of disassembly, but none of them fit me. This one is great. I'm pretty comfy on it, and, I really hate derailers. I've convinced myself that the only way I'll ever go geared again is with a rohloff hub.
I have a fixed/fixed flip flop hub (IRO) and I have a 17 and 19 tooth cog. I figure that'll get me just about everywhere. Bigger hills can be walked.
Reno/Sparks is in a valley, so for any distance you have to go out of town. And, there are hills. I've done a couple of them, they aren't too bad. I plan on heading out toward Pyramid Lake. Out and back is a metric century.
