0.958 miles = 1.54175155 kilometers... nice try man. Dude... they legally cannot be less than 15 under UCI rules. yes, bikes can be much lower than that, for instance my friend's dad has an Orbea Orca he purchased 3 years ago thats a hair under 14. But at the end of every protour stage bikes are weighed, and if they don't meet or exceed 15 lbs they are penalized significantly or even disqualified. Shimano has by no means the majority of the market, in the high end of the spectrum its equally shimano and campagnolo, if anything there's more people on campy. And Di2 adds weight to your bike, generally 50ish grams compared to the equivalent non-electronic groupo (dura ace Di2 vs standard dura ace for example) And its an S5, not a C5. http://www.cervelo.com/bikes.aspx

Bikes on the tour weigh 15 pounds, they have a minimum legal weight. and 0.958 kilograms = 2.11202847 pounds, not sure what you're on. plus bikes aren't just the frame saddle and rims... if that was true then DH bikes would be under 20 pounds too. MTBers trying to talk like they understand road...
