Good work, man - that's impressive stuff - keep it up.
I've been on the top chainring since I got the roadie, only VERY rarely do I ever get down to the 2nd (double on my roadie) and I use the spectrum (barring 6 & 7 unless I'm *flying* down a hill) on the rear (7-speed cassette), always start in 1st and work up. Depending on whether my legs are warmed up, I can hoove it or not (I try not to push myself too much in the first 10/15 minutes of riding). I still don't stand up much when riding, so all my power is from sitting - I might have to upgrade my cyclocomputer to get cadence, as I'd really like to tune my pedalling technique more, when I start to feel some burn in my legs or knee pain coming on, I slow it down and change down to spin up more - but without going to the gym and trying to compare my cadence, I've no way of knowing how fast I'm actually pedalling.
