I ride a triple and I would say probably 75-80% big ring!? I'm glad you asked this bella coz I was just thinking the same thing recently.
I wasn't aware how much time I spent in the big ring until another rider asked me if I found it comfortable coz I ride it so much. Since I too ride by cadence I ride the ring that allows me to keep my cadence between 90-100, usually I ride around 95-103. As soon as the cadence slips, I drop a gear in back first. Once I'm outta gears in the back I move up some gears then drop the front. It just feels to me that I can get more speed out of the big chainring, little gear, high cadence, then the middle ring, bigger gear and high cadence (make sense?). but it's probably just me! lol
Dar: it's probably the gearing on the hybrid bike. I know on my commuter and MTB the cassette is designed more for climbing or comfort riding so the gear ratio is different. I'll top out on gears on both of those and be pedalling a cadence in the 11?s coz I don't have any more gears! and my max/avg spd is always lower on those bikes.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
