Remember that is just a proto guys. All of the frames that have been exhibited at the shows have had a different seat stay brace & wider stays for increased clearance.
Brent is making the frame as stiff as possible so the frames will not have the tapered seat stays but a standard diameter seat stay as featured on the Prolites. This will increase stiffness significantly.
The frame will not be any more flexy than our 26" Prolite 2:1.
Ton – We have advised a custom frame for you due to the sizing. At your height we would need to extend the seat tube which just means we need to brace it a little more to take the extra stresses. The frame would be man enough as it is in Large size but depending on the geo you want, i think it'll be too small for you. We will also custom tune the rear shock for your weight.
