PRESS RELEASE: ZEFIRO is a road and TT proposal and unites power and control.

The ZEFIRO basebar combines Mistral’s aero wing with Ergonova bends.

Plus, it presents our unique Pi WingTM bar extension that is in length adjustable and it is equipped with an hands support that has an aero and extremely ergonomic shape.
The rider’s forearms rest on silicon pads on the basebar’s upper surface, while hands and wrists fall into a natural position on the aerofoil handrest.
ZEFIRO provides comfort for solo efforts and control for sprinting and climbing, perfect for century, sportive, and short-course triathlon riders. It is available in three versions LTD, PRO and TEAM, in high modulus carbon fiber.

The Pi Wing can be swapped out for full-length extensions and is also available separately.

Hasnt this been out for several years now? Perhaps they made some changes?

Tom - 04/16/12 - 11:54am

I think it is short at least one 3T logo. Oh wait, the matching stem will take care of that…

Horrible aerodynamics on those hex bolts. You can’t win anything with this! 😉

Nate - 04/16/12 - 12:50pm

Button head allen bolts for the win!

looks like an indy race car

whats next a wing on the back to keep the rear tire down like the “fast and furious” cars?

Charles O - 04/16/12 - 1:24pm

Would look fantastic on a S5.

looks like medical equipment.

Tommy Nickels - 04/16/12 - 2:03pm

I bet this bar would make invisible aerobats way more comfortable. Not like I can afford it, but is it road race legal if the extension is removed?

Robert - 04/16/12 - 2:48pm

These may actually make sense in ultra-marathon type events beyond 100 miles, where a full TT position is too uncomfortable for the full distance, but an aerobar extension can still help both speed and comfort. Think Furnace Creek 508 or similar.

Best “computer mount” I’ve seen yet 😉

Evan - 04/16/12 - 8:26pm

Cant wait to see these at the local Cat 5 Crit.

I have the previous version on my S5. I don’t like the changes they’ve made especially since the socket heads are now sticking out. In the old version those were enclosed in a teardrop shaped piece of plastic. I must admit I don’t really like the looks of it on my bike (with the PI-wing detached it’s OK), but I do like the handling, ergonomics, feel, drop, amount of handpositions and the amount of control you have over your bike when sitting tucked in the aero-position, etc.

rideTall - 04/17/12 - 12:49pm

if i had to ride these, i’d used all that speed gained with the aero design to go even faster into oncoming traffic!

Spencer - 04/17/12 - 3:25pm

Quite possibly the most ridiculous bar ever.

Robert Jones - 07/06/12 - 5:13pm

I think it looks AWESOME! I do a lot of long distance riding and I think this is perfect! Going on my new EVO!

Jace - 12/22/12 - 7:25am

I have these handlebars on Cervelo S5. They are not aero bars but rather road bars with an additional option for hand position. Traditional aero bars have you resting your elbows on the pads. These bars have you back in your saddle with your distant forearms on the flats and your hands grabbing the pi. It puts you in a very aggressive aero position with your hands and elbows tucked close to your body. You also have really good control of the front wheel of the bike while holding onto the pi. Yes, it gets funny looks, but so does the Cervelo. What doesn’t get funny looks is being really fast. Aero is faster, in a road bike or a tri bike.

I think they look pretty darn cool. And the additional option of riding it in a different form from the traditional road bike style would definitely benefit century riders. Also, group riders cant complain cause you’ll just switch over to the road bike handle during group rides. If it wasnt soo expensive, I would be all over it and I assume everybody else would be as well.
