Overview

Why Is the Zipp Service Course SL-70 the Bike Fitter's Bar?

The Zipp Service Course SL-70 Handlebar earns its reputation as the bike fitter's go-to drop bar by delivering a short 70mm reach that allows proper fit to be achieved without compromising stem length or steering control. With the revised ramp angle, Zipp says proper fit is achievable on even the most challenging setups.

Constructed from 7050 aluminum for light weight and durability, the SL-70 has a 31.8mm clamp. Together with its 128mm drop, the bar suits riders who prefer a low body position. Available in 38cm, 40cm, and 42cm widths.

How does the SL-70 differ from the SL-70 Ergo version?

Both share the same 70mm reach and 128mm drop. The SL-70 Ergo adds a flattened top section with 3 degrees of backsweep for a natural grip on the tops.

Why does a short reach handlebar help with bike fit?

A shorter reach moves your hands closer to the stem, allowing you to use a longer stem for better steering without pushing your total cockpit reach beyond your comfort zone. This gives fitters more flexibility to optimize position.

Is the SL-70 suitable for gravel riding?

The SL-70 is primarily a road bar. For gravel riding, Zipp offers the SL-70 XPLR version with flare and outsweep specifically designed for off-road control.
