During all that time I wasn't able to ride, I realized something: I'm never going to be fast. I'm one of those people who can pick something between 12-16 miles an hour and go... all day, provided adequate hydration and sugar and salt intake. I walk a mile faster than I run one. Changing the bike is really not going to do much for me, in the final analysis. There's not a whole lot out there, by the looks of it. Why should I pay for aerodynamics when I'm not going fast enough to get the benefits? (I should note that I lack a balanced sample: BF's a sprinter, his mom's the same way.)
This sort of removes me from anything competitive, which is fine, as I wasn't exactly planning on doing any. It does make enjoying rides with Mr. Speed Demon harder, but that doesn't matter, as I think we've taken a grand total of about 5 rides together. I've put aside bike improvements or a new bike for the time being, though I'm thinking I'm sticking with the "endurance" geometry of, say, an Avail or Synapse rather than one that is more focused on speed.
And while my graduation present to myself was going to be new wheels, I decided on something that might be a better long-term investment: an indoor trainer.
And a question: for those who are overwhelmingly type I when it comes to muscle fibers, what do you do to improve in other areas?
