Yes, just semantics. Gaffer tape = Duct tape

Yeh any tape will do as long as its sticky enough. You only have a few millimeters of brake to attach it too so has to be strong enough to resist the wind. I just used the same roll of tape that I use for my disc wheel valve holes.
the bit of card just gives it a little structure to prevent deformation/ballooning under the wind that will hit it.

I'm guessing it will only save 1w at most, but the sharp edge of the rear of the brake was annoying me.

I'm surprised nobody mentioned the EE brake in this topic, given its small frontal surface area profile and a cable routing that sticks out less than most other brakes. Not to forget their awesome performance and minimal weight. Just thought they'd deserve to be mentioned. From a frontal view mine don't protrude outside the fork and headset profile nor the seat stays in the rear and the cable narrowly brushes the top tube and seat tube.

I actually think that the EE brake on the rear with an Omega up front might be the perfect match. EE is totally flat in its design so it is like the wind hitting a wall.

I will be doing this set up on a couple of bikes maybe.

that may be because the EE brakes are ridiculously expensive
It's not how much you spend on a bike it's how hard you can ride it.

Not to mention they are full of nooks and crannies, I don't think that is good thing for aerodynamics... neither is "hitting a wall" :)

Quick question guys, which is the stronger brake: TR omega or Simkins egg?
The Tririg might be a little more aerodynamic but I'm not sure it will give good cable lines on my caad 4 aero, and just not crazy about the way the Tririgs look.
The idea behind the Tririg is it acts like a dual pivot brake, right?

really not sure at this point and time...
Tririg or simkins :|

I have now owned both and the Omega is a stronger brake.

I can't say which is stronger since I just mounted my rear Omega but I was more than pleased with my Simkins. They will be for sale soon!

I've had both the Omega and Simkins. (Omega with SRAM levers on my P3 and Simkins with SRAM levers on my P2SL right now, Nokons on both.) The Simkins has a firmer lever feel and when set up with the pads as close to the rim as on the Omega and it fully engages sooner in the lever travel. I like that quicker engagment on the Simkins better than on the Omega. The Omega stops just fine, no issues with stopping power, but the Simkins feels more robust at the lever.

The Omega is much better at dealing with wide rims and going from narrow to wide rims. I could do it with the Simkins with some shaved pads for the wide rims, but with the Omega it is just the turn of an hex wrench.

If EE brakes weren't aero, why would Specialized spec them as standard on e.g. their $18K Venge McLaren? :noidea:
I believe partly due to their diminutive frontal profile EE brakes should be allowed to be called aero and deserve serious mention in this thread! :beerchug:

And since when should 'aero' brakes be cheap when everything else under that title typically costs more? If you wanna go faster, the ability to decelerate should also receive special priority, especially when it comes to cornering. OK, so that may not entirely apply to certain American muscle cars. :wink:

Suppose EE brakes weren't so aero. I'm still positive EE's would favor over almost any other brakes, also those under the 'aero' designation, with a wide array of parameters taken into account, such as 'deceleration-to-drag coefficient'.
Now how about aero brake and levers? Those Magura RT8s look so minimal in frontal surface area! :thumbup:

As some people have testified above, you CAN have it all. The Omega is the fastest production brake on the market (we will be publishing a white paper very soon), and several EE owners have told me they prefer the Omega in terms of its power curve and overall stopping power. The Omega is also cheaper than the EE, so it seems like a win-win. It is a few grams more than the EE, but still lighter than Dura Ace, Record, and RED.

with regard to the eebrakes, i talked to craig about a year and a half ago suggesting a fairing (carbon of course) that could snap into the main pivot holes. one could even incorporate the return spring into it, giving it actual purpose and technically being uci legal (not that i care about that...)
i may try to make that myself.

The omega has great stopping power, not quite as much as a conventional dual pivot (7800/7900 or record or red) but surprisingly close, mine are on a P3 with USE tula bars (which have integrated brake levers, which suck the life out of braking power and feel, but are very aero.)

I was able to stop my bike rapidly from 30mph with 1 finger braking on just the front brake using this set up with out any issues. I must say i was surprised how good they are! If i had the spare cash i'd replace my road bikes brakes with them too!

How much weight do you figure that will add to a pair? This is WW, and adding weight will take away some bragging rights for the manufacturer, since aero claims may not "sell" as well as weight.
