How low can you go?

A little bit aero and a little bit road might be the best way to describe the new Zipp SL-70 Aero Carbon Handlebar. Building on the legacy of the VukaSprint, it features a carbon construction and distinctive shape built to take you to the top of the podium.

The SL-70 is constructed from unidirectional carbon fiber that has been shaped using Computational Fluid Dynamics (CFD), which is the same software Zipp uses to design its hailed Firecrest wheels. And although the shaping of a handlebar seems inconsequential, Zipp actually discovered that you save approximately 6.4 watts at 30mph using an airfoil-shaped section in place of a traditional rounded section.

The SL-70s feature a 70mm reach, giving you proper control over your steering. A 128mm drop allows plenty of room to adjust hand position, and the drops sweep outward at a 4 degree angle to allow riders to tuck into an aerodynamic position with hands wrapped securely around the bars. A 10-degree ramp angle on the brake hood mount area of the bars eliminates the need to up-rotate them to achieve the correct brake hood position.

The Zipp SL-70 Aero Carbon Handlebar features a 31.8mm clamp section. It comes in four widths: 38cm, 40cm, 42cm, and 44cm and in the color Carbon.

Super fast bar

  • Familiarity: I've put it through the wringer

I've paired this SL-70 Aero bar with Zipp's new SL Speed stem and together they combine to create a very stiff yet reasonably comfortable ride. The deeper drops on this bar are a change for me, they are slightly deeper than my old Zipp Contour SL bars but I feel like with this bar aero is paramount and this set up helps to achieve a flatter back. The tops are a bit unnerving to ride dirt roads on as it feels like you can just slip straight off if you are not holding on tight. To augment this I've ordered some Vuka grip tape and it is definately helping to reduce that feeling.
Note- I've been able to mount my SRM PC-8 next to this stem clamp without any issues.
All in all an incredible bar/stem set up that feels and is faster than the competition!

Stiff, Aero, but not obnoxious!

  • Familiarity: I've put it through the wringer

I am on my third bike with an SL-70 Aero bar now, and I have to say that I absolutely love this bar!

I can honestly say that I do not notice any difference in stiffness between this and my Enve or Zipp SLC2 bars on the same bikes.

The bar geometry is perfect for riding in the hoods and drops comfortably; most notably is that due to the short reach, the aero section tends to stay out of the way of your knees when you are out of the saddle.

The tops in the aero section are also not too large as to make holding onto them uncomfortable and cumbersome (and I am not afraid to admit that I don't have a giant's hands).

You do have to choose your computer mount carefully as Barfly and most others will not fit next to the stem, especially when paired with Zipp's SL-Sprint stem. All K-Edge mounts work perfectly with this bar and any stem you could choose from our selection.

Do the drops have the Zipp ergonomic ovalized shape, or are they round?

The drops have a completely round shape.

Excellent bars but at a cost

  • Familiarity: I've put it through the wringer

These bars will impress--they just look fearsome. But more than that, there's an performance advantage to the airfoil shape of the tops. First, the tops are actually more ergonomic if you use them for climbing. Second, Cervelo, finding that the handlebars contribute a just a bit less than 20% of the drag of a bike's frame, is now equipping its S5 with its own aero road bars. Every watt you save means extra work for your competition. If you often use the "praying mantis" position you may want to tape everything as you would with regular bars, but I prefer to leave the tops free in order to save every watt I can.



I don't notice any problems with road vibration or much flex when sprinting hard. The drops are well designed and easy to reach. The internal cable routing seems well designed and easy to use.



As noted in one of the comments below, the bar is not designed for clip-on aerobars or is it well suited for a barfly computer mount (unless you have a narrow stem, I suppose). So long as you have a round stem you can mount a computer there, but if you do as I did and pair the bars with a Zipp Sprint stem it makes mounting really awkward. Fair warning.

I have a Garmin out front mount on mine. To get it to align properly, I heated the underneath of the mount with a lighter, while twisting with some pliers to get the desired angle. Then held in place until cooled and now have perfect orientation for my Garmin 810. FYI, some lights are hard to mount to the top of this bar, so I use a Light & Motion Urban 700 and place mount on top of foam tape on top of bar. Doesn't move at all.

K-Edge computer mounts fit perfectly on my SL-70 Aero bars when paired with the SL-Sprint stem. I did have trouble with Barfly and the Garmin mount though.

If the bar is a 42 is that measurement done on the hoods or in the drops?

Best Answer

Carlos, the width is measured center to center at the brake perch. Hit me up directly with if you'd like. btowery@backcountry.com

Fwiw the 40cm size measure 42cm (drops, center-to-center), but measure 40 cm at the top, due to the flaring of the drops.

Hello Jim,



Thanks for your question.



At this time we only have the 44 in stock. We have two on hand currently. However, we are taking backorders for the other size.



I hope this helps.
