Yes a dedicated TT bike would be nice, but I've used up my bike allowance on the new roadie - not only that there is likely not a stock TT bike made that would be small enough to fit me and I really can't afford to buy a custom TT bike right now- Cervelo I definitely know does not go small enough.

Maybe if I wasn't riding as a cat 4 and I was better at TTing it might make sense to go there, but at this level of racing improving my overall fitness makes more sense than buying more equipment. I realize that my position is never going to be perfect on a road bike with TT bars, but I'm not doing the ironman either. The TT's that I do are generally short (10 miles or less) and are part of a stage race. Most of the women at my level are not riding dedicated TT bikes, disk wheels etc. so I don't feel that I am laboring under a huge disadvantage right now.
