Yeah all I've found so far is that the moto built up minus pedals is 17.1 and the kilo tt frame only 19lbs not sure about the acuracy on the kilo that was from a forum. I'm riding velocity deep v's I tried doing a carbon wheel set (real design) but the wind was killin that setup pretty quick. Any input on a alum being a smoother or harsher ride? That's also another factor
