Aero brakes



Based on Tom A's front brake (which is a Tektro rear mounted on the front and actuated as a centerpull, rather than a sidepull V-type brake), I am going to try and develop my own aero brake.

Surprisingly, bike companies haven't come up with anything good as far as aerobrakes go, since the 80's and 90's.

I actually had this idea for an aero brake when I saw the Specialized Transition bike 2 years ago, specifically, this picture:



That looked like a Ubrake to me, on a special fork built to hold a U brake. That fork is probably tough to get, but luckily ubrake adapters are sold.



Will this work? Brake-wise yes, it should work. Aero-wise...will it integrate well enough into the fork crown so as to become one with the bike/fork? Or will it stick out into the wind in unplanned ways?

Well, I get the brakes in two days and the bike in three. We'll see.

Before I plunked down the $30 to try it, I did some mockups in Photoshop:

First I laid two brakes that looked good to me on top of each other, to see which was smaller. The images were different sizes originally, but I resized them based upon the pivot bolts.



Notice the pink "Hombre" brake is narrower near the brake pads.

Then, I mounted them onto the Ubrake adapter:



Lastly, I mounted them onto a photo of a fork (I dont have the Jetstream fork as pictured, but it was the best photo I could find of a fork at the time):


The location on this last photo is an estimate, not sure how high or low the aerobrake will actually sit. We'll see...
