However, two years ago I was fortunate enough to get a custom built Serotta CXII (roman numerals for 112, the bike mileage in an ironman), a bike with tri-specfic geometry. I got this bike the year I did Ironman Lake Placid. So, I spent many, many hours on this bike prepping for that race. Last year I didn't do a lot of winter work on the trainer so as soon as it was nice enough I was out on my Serotta and didn't ride the Trek much. This year my winter training was much more regular and I used my Trek just to keep the mileage off the Serotta since I was just building my aerobic base up.
So, when I got back on the Serotta after several months of using my Trek it made me realize how much I love the Serotta and what a difference a custom bike makes.
