We've fiddled with position and improved the fit but I've also spent a lot of time on the TT bike building quad strength.
My saddle is farther forward on the TT bike than the road bikes, just as @
Ali89 points out. Maybe that accounts for the difference, I'm not sure.
Yes, that accounts for the difference. It's well known that pushing back in the saddle and/or setting the saddle further back engages more glutes. I don't know why though. Have you seen this?

I've had good results in leg extension strength from doing one-legged presses at the gym. One can use either a machine or the leg sled. I push with my toe, not flat footed. The further down the foot board you put your toe, the more quad you get and the less glute and ham. Twice a week, super effective. On one day, I load it up to failure at somewhere between 4 and 10 reps.
