Climbing on a tri-bike geometry has one drawback for me. Due to a steeper geometry, my saddle's nose is a fraction in front of the BB. When I stand up, the nose of the saddle will hit the back of my thighs like a metronome with every rotation of the crank. It is annoying enough to keep me planted on the seat. On a road setup with the saddle relatively further back, I enjoy standing now and then.
