Did anyone else see the hacked/modified Shimano Dura Ace brake?

and how about him riding 180 cranks?
How does that bar pass the 3:1 rule?
That is an old skool mod. I know folks from back in the days of “Drillium” would do that to their calipers for no reason more than they wanted to drop a few more grams when they installed their TRP kit.
I’m pretty sure that is a 3T Mistral. It is designed to be fully UCI legal from the get go.
Must be the angle of the photo.
So, after viewing these pictures, I wonder how many people will be modifying(hacking?) their DA brakes like this?
Why would they cut it?
Why would they cut it?
If you look at how short the cable is, that there would be a very tight bend from the stem (I suppose Nokon would resolve that). But, it is an easy way to get a direct route to the caliper from the center of the stem. Plus, with full time tech staff and nightly rebuilds they dont need to worry about adjustment due to pad wear and what not.
I am pretty sure that they simply wanted the brake cable to run in front of the head tube.
Same thing they did last year:

.
The bolts on the back of the seatpost are a good idea, if you have Di2. Does anyone know if a standard bottle cage would fit there, too?
link doesn’t work.
I can’t really tell what’s going on from the pics… does anyone have any closeups of modifying a DA caliper like this?
**edit:
found a better pic:

Sacrilege. If you´re going to take the hacksaw to a front brake, at least use a cheapy one, a Sora BR 3300 or a Tektro low-end one.
I’m more surprised nobody is bitching about him running what amounts to about 3 inches of spacers under his arm rests. Why isn’t he riding a bike that fits him!!
John Cobb had some instructions on how to modify a standard caliper into an “Easy Aero Brake.” I can’t find it right now on the web, since the Blackwell site is out of service. He cut off the arm and the mounting bolt. It fit into the profile of one of his forks.

I know that I won’t…here’s how I commented on this in the other “New Felt DA” thread":
The part I loved best is that he’s running a “Cobb’d” front brake: http://www.cyclingnews.com/...tions-felt-da/120344
Tells me that Millar (or his mechanic) really sweats the details!
…except for the detail that Damon Rinard (when he was at Trek) tested that type of modded brake in the wind tunnel and found that at 0-10 deg yaw it wasn’t any faster, and that at 15 deg it was actually significantly slower…and that info is publicly available.
Hmm. That is interesting info on the Cobb’d brake vs standard and air flow around the front of the head tube. Makes me feel even better about the Simkins brake I have on my bike.
The reach fits him, the stack does not.
A bigger frame would need a shorter stem and less spacers.
This would be less aerodynamic. Simple. For a frame which uses stem spacers, this would not be less aerodynamic (it’d be much the same) but with these disappearing stem bikes, using narrow armrest spacers is a very aerodynamic solution. Otherwise there would be a higher head tube which would present more front to the wind.
This (armrest spacers) is the mechanism for sizing the Shiv as well.
