I like mountain bikes, a lot. I seem to spontaneously acquire new and interesting(to me) bikes on a fairly regular basis. I do however lack hoarder/bikeapocalypse prepper tendencies. If a bike in my stable isn't seeing use it is better off being turned back into cash, or gifted for karma's sake. Dusty bikes aren't cool.
Here are a few bikes I owned, but never even rode. Weird.
Socom. The race bread stealth fighter of yester-DH-year. 32 pounds or something crazy. No time for DH. What a loss. Sweet bike. It did end up living a useful life under a local that had the time and interest to give it the attention it deserved.
I actually rode this one once. That's all it took. Capitol Forest was not yet ready for 650b(and neither was I). Just noticed the Egg Beaters on there. My apologies.
