Zipp SL-70 Aero. If you are looking for one of the stiffest and most aerodynamic handlebars that is still UCI approved, it may well be the Zipp SL-70 Aero you are looking for.

It is aerodynamically optimized in every way it can.

It is made of "unidirectional" carbon, which gives a stiffness in a special class, but still provides good vibration damping.

The handlebars are around where you mount your stem and where you can have space for a mount for your bike computer. A little further out, the profile becomes flat, so you cut through the wind and save energy.

The handlebars have often been in a wind tunnel during development, and Zipp has found that the flat section on top saves you 6.4 watts compared to a regular round handlebar at 48.3 km/h.

The handlebars have black decals.

The handlebars have a system for running cables inside the handlebars, so you don't feel them and they don't create wind resistance.

It can be used for both mechanical and electronic gears.

However, it can only be used for mechanical brakes.

The width of the handlebar is 400mm center to center from the drops.

The handlebars have 70mm reach and a drop of 128mm.

There is a small outsweep on drops of 4 degrees and a ramp angle of 10 degrees.

Your STI grips can be adjusted within 10 degrees, so you can put them where it's best for you.

Mounted with a 31.8mm stem.

The 420mm handlebar weighs 240g.
