Hi, the bigger bike, white tape, it's not too big, rgds, sreten.

I see a little more rotation of the torso on the bigger bike,
i.e. your lower back is tilted a little more forward, and
perhaps reading too much into just two pictures, for
the bigger bike your spine has a smoother curve.

For no reason, you look better on the bigger bike.
Thinking about it, a little more stretched out, racier,
at the same time you seem to look a little scrunched
up on the smaller bike, less natural, in comparison.
