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. This matters most on challenging setups where every millimeter of cockpit reach affects power output, comfort, and bike handling. The revised ramp angle makes ideal positioning achievable across a wider range of riders and frame geometries, making this bar the logical starting point for any fit-focused road build.

Constructed from 7050 aluminum with a 31.8mm clamp for modern oversized stems, the SL-70 is built to hold up through years of training and racing without compromise. The traditional round drop shape provides a classic, predictable hand position in the drops and a comfortable neutral position in the hoods. Available in 38cm, 40cm, and 42cm widths to match your shoulder width and achieve the precise fit that makes long rides and hard efforts feel effortless.
