My current stable is pictured below (click for a larger view):
Calfee Tetra - SUB 16 lb. all carbon mountain climbing bike
Specialized S-Works "Festina" - 16 lb. criterium speed machine (wheelbase as "tight as a tiger")
Specialized S-Works "Domina Vacanze" - 17 lb. aero bike for cheating the wind
Airborne Valkyrie - 18 lb. rocker-recliner on wheels, so smooth, you swear the back tire is flat
Specialized M2 - 18 lb. daily rock 'n roll grinder
Univega Modo - 19 lb. cro-moly smooth operator
Dahon Allegro - it splits in 2, lays in a standard airline-sized suitcase, and travels anywhere for FREE (just put down 60+ miles in San Diego last month)
Univega Carbolite - 19 lb. stealth "nobody will believe your speed...until you pass them"
Specialized Sirrus - 19 lb. "neither rain, nor sleet, nor dark of night stops my winter training"
LeMond Team Z replica - 19 lb. retro "I remember when LeMond won...." story swapping catalyst

MTB's
Santa Cruz Blur - 24 lb. "what rock?"
(not pic'd) Univega Boralyn - 22 lb. corner carver, fireroad flyer, singletrack speeding wicked-light hardtail
(not pic'd) Marin Pine Mountain - 26 lb. classic all-around trail machine

Tandem's (only 12 pic's allowed)
KHS Alite - ugh...trying to sell it
(pic'd) Tsunami Ti-Boom - the new twin-rider, draft us at 30 MPH and I'l explain how the beam works

Bottom line, we all have vices - mine is bikes, cheaper than booze, women, dope, or gambling. Luckily, it is also a "healthy" habit to keep.
