Hey Mitch-

I have to change out a frame (BMC Large) and am excited to make the switch to the Speed Concept. Can you help me make sure I have the right size? Current fit is 508 x and 698 y. (to center pad) 6'2" tall. I would say current fit is on conservative side for me so I'd love some ability to lower the front end in the future if my back allows.

Thanks!

Matt
