I did my first TT on a SS last night. No pics. It already had basebars, and I borrowed clip on aerobars. I geared it 53-18. It is a mostly flat course of 10.2 miles, my usual time is 29:15-29:50 on my road bike. SS was 32:14 by my timer, the official results haven't been posted yet. I was very slightly overgeared for the course and my ability.
