Today I went for another time trial session. This time I had almost the complete setup I’ll use for the State TT next weekend: longsleeved skinsuit, aero helmet, aero bars, and shoecovers. The only thing missing is an aero front wheel I hope to borrow, and possibly and old-school wheel cover if I can find one. I lowered my handlebars an additional 5mm, and think I have settled on a saddle setback about 8mm forward of normal, with about 6mm additional height.
Today I rode the Boulder TT Series course (the Lyons to Boulder direction), which is exposed rolling hills. I used to ride to Lyons a lot as a kid, and back then I think 34 minutes was the best I ever did on my mountain bike. I can’t make the Boulder TT Series since I work every Wednesday, and my time today was pretty bad compared to last night’s series opener, but according to the weather station they had a quite favorable ~8 mph tailwind.
I was properly recovered this time and went out for an approximate 2×20 workout which went well. I rode Boulder to Lyons, and Lyons to Boulder. This time I saw my power, HR, and RPE were closer to normal. I still saw my threshold power about 10% lower than on my usual road setup. I know it is normal to have somewhat lower power in a cramped TT position, but I don’t quite know what level of trade off gives the best overall speed. I guess this is what the windtunnel is for…
Anyway, I hope to have an aero wheel setup to take out to the State TT course next week, probably on Tuesday.
