I rode at Yargo yesterday in between dentist appointments and did 2 laps, one SS, on geared. I have to say that I am pretty even on them. The geared bike feels faster but it is heavier. My laps times are about 5 minutes off last summer's and I am still about 10 lbs heavier than I'd like to be (who isn't)?
I have not done 3 hours on the SS yet and maybe Saturday will be the day.
