Hmm...let's see now. My first "road" style bike w/drop bars was a Specialized Sirrus that I bought many years...I'd say I was in my early 20's at the time (I'm 45). After I tired of that bike, I got a Nishiki mountain bike...it was lime green.
I rode that bike for years, before deciding on a Trek Navigator 2.0, a comfort bike. I rode that bike up until I got "bit" by the triathlon bug back in 2008. I bought a Trek 2100 WSD, that served my purposes well...only it was a tad too big for me. A year later, I decided I wanted a faster, better bike because I thought I would continue doing triathlons. So I bought a Cervelo Carbon Soloist. I rode that bike for 1 season, and never did do another triathlon that year. I loved my Cervelo, but sadly it was a bit too aggressive for my old, messed up back...so I sold it and bought a more relaxed geometry road bike last May - a Cannondale Synapse Fem 3 Carbon, my current bike.
