I finally had a chance to play around with getting an Omega on the rear of my S5. Here's what it took:

An M5x14 button head SS screw (this needs to be tightened with a ball end hex key. edit: before the cable stop is mounted to the brake)
2 large and 2 small spacers (as supplied with the brakes...luckily I only needed one small spacer for the front so I could use the thick spacer from that brake)
A slightly shorter brake mounting nut (the nut supplied with the brake is just barely too long...it bottoms on the washers before tightening with the S5s mounting plate).
A plastic cable end ferrule that I could trim short
Some creative filing on the backside of the cable stop plate.

Oh...and it appears the brake arms have a bit of "toe-in" built in (tapered part of arms slightly inboard), which works great in the front brake position, but I found out that it leads to horrible squealing under heavy braking when the brake is mounted on the rear due to the "stick/slip" that happens when pads are angled the wrong way. Not wanting to "shave" the pads, I decided to put a couple of plastic shims in between the pad holder and the brake arm in front of the mounting screw to accomplish the proper toe-in on the rear. There was enough "slop" to angle them just right when I tightened pad holder mounting screws. Squealing gone :-)

Do you have one on the front too? Can you post pics of that? I am thinking of doing the same on my S3.

Bullshit. I dont buy that for a second. We were breaking the hour in the 40k long before the Scott DH, let alone all this gibberish.

Again, I love it, I love the looks and I love tinkering. But three seconds? I hope there is a flux capacitor under the cover.

It is a guess, up front it saves about 6 per Andy Coggan's wind tunnel test.

the rear will be less.

Thanks - my issue that I did not point out was that it was the rear...up front, I really really get it. I for one damn near never use my rear brake (thus Campy also agrees and has had a single pivot for years).

Would you really run these on a road bike in a crit/road race? Ugh.

I have an Omega on the front of my P3-SL and it is great, but the modulation/stopping power is awful compared with any other top tiered brake (Red/Force, DA/Ultegra, etc.). I'd likely LOSE time/watts in a pack/cornering than in drag savings. Love the design though.

Carry on if the S5 is your TT rig.

But you rarely need to hit your brakes if you are cornering fast! =)

I would think it more of a safety concern than a cornering disadvantage, but maybe with a big STI lever it isn't so bad.

actually running it on the rear but NOT the front for a road bike might be perfectly reasonable.

I'll go admire my jersey I took home 2 days ago in my state road race without an aero brake (again, I left it on my TT bike where I managed only a silver) ;-)

Sure, I realize that a rear aero brake caliper by itself will likely never affect your placing in a road race.

But, you need a brake back there, and you don't really ever need to use it, so it might as well save you a couple grams of drag, eh?

A front disc would be dangerous.
An omega rear isn't.

As for the rear disc, I would do it if not for peer pressure. Its actually safer, no skewers or derailleurs going into your spokes!

Nice work, Tom!

I have two questions:

1) Are you concerned at all that the filing on the rear cable holder will weaken that piece?

2) What advantage does the Omega have over the Egg? Aero (besides the possible naked cable)? Leverage? Better modulation? Easier to adjust?

Cheers.

That's not the question...the REAL question is what do I gain over THIS:

In reality, the Simkins on the rear mates up with the S5 much nicer than anything else...BUT, it has some drawbacks in that it wasn't designed for wide rims...centering and width adjustments are a bit of a pain.

That's something the Omega does much better. Plus, it allows me to have matching brakes front and rear :-)

Of course it is, and I generally agree with not using one up front for safety reasons. On the rear though you are going to have no problem getting 100% of your rear tire, which isn't much.

Really? Are you running the Koolstop pads? I find that there is WAY more than enough power...in fact, on the rear I can easily lock up and skid the tire if I want to do so. I have no issues with the modulation.

I noticed that there's a bit of a "soft" lever feel with these brakes. That's actually a function of their high leverage. In fact, I recommended to Nick that he might want to change the wedge curve slightly to curve outward as the brake pads press against the rim. This would actually reduce the leverage but give it a more "firm" lever feel when the brakes are engaged. edit: But, that's really just a "feel" thing, and not a performance thing...

I would argue it saves no time at all, considering the rear brake position was intentionally shielded by Cervelo witht he seatstays. Now there's a huge gap in between the stays and the rear brake, allowing airflow to separate there at yaw. I would say you LOSE time with going with the Omega rather than the Simkins

Don't forget that the rear brake housing is brought in closer to the bike centerline...and, I eventually plan on using some Nokon housing back there and bring the housing right down the trailing edge.

So...there could be a bit of savings compared to a sidepull design (including the Simkins) from that.

However, any potential time savings from mounting the Omega back there was pretty far down on my reasons for doing so.

I also have been contemplating making a custom S5 brake mounting plate that would fill that gap :-)

On the rear, the cable housing brought into centerline and the brake being easier to adjust for varying rim widths (my TT rims are narrow and my road rims are wide) were the 2 big reasons. Thirdly was to match the brake on the front :-)

According to AC's mini-tunnel test, the Omega is slightly more aero than the Egg on a fork.
