I'm really curious to know...thanks!
So i rode both bikes back to back yesterday and the specialized owner also rode mine. As expected the differences in the bike setup made it almost impossible to tell exact differences in the frames ride feel. The specialized comes with 42 cm handlebars and 38 mm rims while mine comes with 38 cm handlebars and 50 mm wheels. In addition to that the bikes are fitted for two different riders. Both bikes felt great but obviously different due to the different setups. I‘m almost certain that the difference between the frames is marginal at best. Maybe if you are doing 1500+ watts sprints the specialized feels stiffer but i can’t really prove that it’s just a guess.
I‘d love to have both frames and put the exact same setup on them both fitted for my body proportions. This way the comparison would come down solely towards the frame. But this will unfortunately never happen.
