....so a pretty good rider goes down a long really fast hill in both dry and wet conditions using rim and disc brakes....
....the quick and dirty takeaway...in over 9km of screaming descent with some wicked switchbacks....the rim brakes "win" by two seconds in the dry and "lose" by eight seconds in the wet....and on a top end bike you would be spending near $10,000 to go disc and then hamper yourself with extra weight for the "money" part of the trip, the uphill....and you don't believe me go ask Marcel Kittel, he knows stuff and even has some practical experience....

When all we see is Kittel's Venge on stilts over and over and over again people are going to assume that 7.9kg is normal for a disc equipped bike. Throw a set tubular wheels on a Focus Izalco Max, Giant TCR Advanced, S-Works Tarmac or a few more lightweights out there and you would need to ballast the bike to comply with the 6.8kg UCI weight limit. "Hamper yourself"..... You sure about that?
....last I checked the bike industry isn't hampered much by the 6.8kg limit as the vast majority of bikes go to non-racers....so do you actually have a point or just trying to get the last word in....?....
