Rode the TT bike for the first time since April with that new TT position I dialed in after my abortion of a TT @ Sandy Hook (the one with the abysmal position). New position is not only more aero and faster (I averaged 23.5 mph over a 17 mile training route, about 1 mph faster than my previous best) but considerably more comfortable. Haven't changed it since these photos:
I now wear official cycling socks, that's probably it. I had to shift off my sore elbows now and again, but generally I had a significantly easier time holding the aero position than in the past.
