Curious to know what was your first 'cross ride?
I'll start - after riding my mtb for a bit in races, I had a zebrakenko that took 27" wheels, and had a mix of suntour and dia compe on it, including sidepull brakes. I think somehow I got some specialized 27" tricross tires on it. It since has gotten canti braze ons on the rear (via Rhygin), gone through three forks up front, and is on its third paint job since I bought it used. Now the gear cable housing stops routings and hanger are cut off (via Rock Lobster). With its horizontal drops, it still sees limited singlespeed use.
My first real cx bike was a lugged steel Moser frame and fork, Suntour XC pro cantis, SRAM 9.0 SL mtb brake levers modified to be inline, Ultegra brake levers, sachs quartz road front and rear derailleurs, Mavic Reflex clincher wheels with DA hubs (I still ride those wheels on my commuter), green Michelin Muds Selle Italia Turbomatic saddle. I can't for the life of me remember the crank, but for some reason I think it was an Suntour XC Pro 110 BCD. Here's a pic:
It handled a few New England seasons, lots of snow riding, '98 nats (devens) and '99 nats (presidio) and a mess of Kauai mud. Mud clearance wasn't great. My teammate had the same frame but in a much smaller size. Pontoni asked to use it as his backup bike for the Supercup but frowned so badly when he picked it up. It wasn't light. But he still took it to the pit.
Where is it today? I remember selling it to a guy in the parking lot of the Westin Ski Track after a day working there. It's funny how those are the types of days I regret the most. Selling a bike? Not usually a smart thing for a bike geek unless you really hate it. I'd love to have it back. Oh, the memories! I saw one on eBay a month ago and was tempted to buy it but know it wouldn't be the same.
Post yours...new or old, let's hear some stories. It's kinda like your first love, right?
