Anyone have any data comparing these two? I saw the chart comparing the ventus and the zipp with the ventus being considerably faster but haven’t seen anything on the Felt Devox yet.
i bet the ventus is a little bit faster than the felt devox just because the profile is deeper and manage the air better. perhaps superdave can give us some data. neither bar really interests me though because it lacks the ability to shift the hand position up more than a few degrees. the aftermarket ventus like bontrager bar looks promising, but has a pretty high stack.

The stack is an issue for me, but do you have a picture of what one you’re talking about?

.
i would guess ventus faster, because of the small profile of the pursuit position.
some things you should know, however. first, ventus is 1pc and has 1 stem length and 2 pitch options, if it hasn’t changed since i last investigated it. that 95mm virtual stem length better be what you need.
the ventus has a fairly high pad profile, with the pads sitting 5cm above the centerline of the (virtual) stem clamp, versus the unpedestaled devox sitting 2.5cm above. so, the decider for you might be what you need geometrically. for me, the devox was the perfect solution for my slice, while the ventus was perfect for my p3. had a tried to put either of these bars on the other bike, it would have been either a disaster, or just simply unachievable, assuming i wanted to retain my fit coordinates (which is non-negotiable for me and should be for you as well).
if you choose the devox, the clamp diameter is 26.0mm. no problem there, just, you should know that before you go ordering any stems.
the devox purchase requires a separate purchase that the ventus does not require: brake levers.
the ventus’ brake levers do not have return springs.
the devox comes in sub-assemblies, with everything being available either in carbon or aluminum: extensions, base bar, clamp/pad system. everything’s interchangeable. if you choose all aluminum, it’s a boat anchor. all carbon, it’s light enough, but quite pricey.
pretty high stack? that looks huge. haha

yeah its massive. based on the speed concept thread, it looks like sc owners arent as aero as their bikes.
I may end up going with the felt. I’m still undecided if I like my super drop position like in my profile picture or a bit less with a flat stem. Which makes the felt much more enticing. I’ll actually be able to get a good idea this year now that I have a p4 where the seatpost doesn’t slip an inch every ride…
If you go the Ventus 1 route and you have a 2011 P4 then you will need to cut the bar to make it work. This might also be true on the 2010.
If you do have some stack you can tweak the effective stem length (really reach) of the Ventus, a little, by working between aero cup risers and using spacers.
based on your profile pic, i wouldnt suggest getting the felt bar. i would recommend a longer stem and bringing your front end up just enough to keep your hip angle the same.

That is one of the other issues I have, I’m not going to buy a brand new bar and Kamm tail pseudostem. I wouldn’t mind doing that on a used one but finding the -17 bar used isn’t exactly a walk in the park.
what would be the reason for that?
The felt devox can be set up with the pads almost right on top of the base bar- to get you a super low stack. I have the non-uci legal version and they are really nice, lightweight, and apparently quite aero. I used to have the HED 1 piece classic aerobar and these also had a super low stack. The HED’s tested really well, and these feel faster. They definitely look cleaner with all internal cable routing.
I don’t know if the new Ultegra Di2 will work with these if you want shifters on your brake levers (they will have thinner wires), but the current Dura Ace Di2 does not - as I think the wires are two thick for the internal spacing//entrance exits. The UCI legal Devox bars do work with DA Di2.
A great review with pictures can be found here: http://www.tririg.com/articles.php?id=2011_04_01_Felt_Devox_Aerobars
Lastly, I ended up using Zipp extensions with built in shifter bosses, I am using HED butterfly carbon cups (the Devox are awfully uncomfortable), and am just using regular Arundel Gecko Grip Tape, instead of the Devox rubber grips. The combination is amazing comfortable, allows my forearms to be very close, and gave me a super low stack.
Mark - would you mind posting some pictures of your set up when you have a moment.
What about the new Brezza Nano bars? Smaller width, doesnt quite have the deep profile of the others. How would that compare on the drag charts against the Devox and Ventus?
Plus its Di2 compatible, you get your own stem and brake levers.
