As per the title I've been musing over this for a while, looking at things like the Genesis Croix De Fere, Orbea Diem Drop, Kona Sutra and Honky Inc, Marin Toscana...to name a few. There are also a few of the flat bar road/hybrids with discs and the recent change to UCI rules for cross racing, to permit disc brakes, will mean more coming out. But they all lack something componentry wise and, most especially, in weight, all coming in at 25lbs plus.
I'd like a drop bar bike with Avid BB7 road mechanical disc brakes, compact chainset 34/50, 10 speed 12-27, cross top levers and clearance for up to 32mm tyres. Coming in at sub 20lbs!!! By my reckoning:-
2.41lbs = bars, bar tape, extra padding(for my delicate handies), Dura Ace shifters, Tektro Crosstops, handlebars and all cables including outers.
7.98lbs = chain, 50/34 chainset, BB, Pedals, BB7 brakes including rotors, front and rear deraillers, headset, seatpost clamp, stem, spacers, saddle and seatpost.
2.20lbs = 700x32 tyres with rim tape and inner tubes, allowing about 350g per tyre
So that comes to 12.59lbs leaving only 7.4lbs to cover frame, forks and wheelset in order to reach a total weight of 19.99lbs, is it doable? I can find carbon disc forks at 1.5lbs, so that leaves us 5.9lbs for frame and wheelset. Or have I overestimated for some of the componentry weights?
