My current arsenal includes: Kona Kilauea (26"hardtail mountain bike, built as a singlespeed), Salsa Mukluk (fatbike), Voodoo Soukri (geared 29er mountain bike), Milwaukee Bicycle Company singlespeed 29er (Waterford/Gunnar steel frame with carbon fiber fork), Trek Madone 4.5 (road bike), Trek 2300 (road bike I keep in Colorado), Rocky Mountain Solo 70 (wife's carbon road bike), a Chinese carbon Pinarello knockoff (road bike...for sale), Schwinn Stingray (decoration in the basement), and a Schwinn Twinn tandem from 1970 that was given to my parents as a wedding present (my wife and I now use it as a bar cruiser). I've also got a Colnago cyclocross bike in the garage that a friend lets me borrow for the CX season and muddy training rides.
Last year I sold a Dean titanium mountain bike and a Titus Racer X full-suspension mountain bike.
This list ALMOST makes me think I MIGHT have a problem....
