Zachwrote a review of Zipp SL-70 Aero Carbon Handlebar on May 4, 2016
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!
