Yes, this is true, the geometry of the bike uses power from different muscles in your legs and does so more efficiently. When you get to the run, you have less of the brick legs feeling (not none, but less).

I do feel the difference between my two bikes, but one of them is also well-fitted and cost 3x as much as the other, so I don't know if it's a totally fair comparison. I feel like my tri bike uses my entire leg and more of my glutes rather than more of my calf and quads. When it comes time to run, my legs are happier to oblige. It's been a long time since this feeling was "new" to me so it's also hard for me to tell if I've just adapted.

My "perceived effort" ratings for my tri bike and road bike at the same heart rate are different. Things are easier on my tri bike and it seems like a lower muscular effort to maintain that heart rate, while on my road bike it feels like I'm working harder.

I'm glad I bought mine, but I knew as soon as I sat on the saddle and took that first 1 mile ride that I wanted her.
