Looking to upgrade my old trek 1400 (2001) frame. (105/ultegra mix group, FSA SLK compact chain ring/cranks, wh-r560 wheels)
Been looking at the Ribble deda em2 (1050g), ribble deda sc61.10a carbon monobox (1175g), or even the cheaper ribble 7005sl carbon monostay (1490g)
Looking for comfort/lightness without to much flex as I'm 90kg
Any reviews
