I've spent too many hours admiring other people's fixed creatiions (thanks for the great site Dennis!!), so I've finally decided to contribute my own, after seeing my co-worker's fine ride up on the site (#5221 - notice the similar backgrounds?).
My beautiful 54cm Colnago Super SP, bought new from Renaissance Bicycles on Central Park West in NYC (Mom's college friend owns the place!) in the winter of 1990-91, was relegated to commuter status after finally buying a new road bike in 2005. Here are the specs: D/A 7401 cranks, w/ 44 x 16 drive train. Wheels are formula hubs laced 32 3x to mavic cxp22, ultegra 600 aero seatpost, w/ flite saddle, mavic stem with handlebars I found in the spare parts bin (with pieces of a tuna can jammed between to make it clamp tight!), shimano 105 front brake w/ bmx style front caliper, ultegra bb w/ the loose balls - still runs smooth, and an anonymous specialized headset.
Once again, thanks for the super site!
Best, Joseph Hu - Philadelphia
