A bike fitter’s dream

Service Course SL-70

The Service Course SL-70 is the bike fitter’s go-to bar. As brake hoods have become longer, handlebar reach has trended shorter to compensate. The days where every rider used a deep, long “Belgian-style” bar are long past. The short reach to the hoods allows a proper fit without compromising stem length and steering control. 70mm of reach has become the default for many bike fitters, and based on their feedback, as well as pro riders, the Service Course SL-70 has been updated with the newest features that riders need.

A new variable radius drop, matching the carbon SL-70 Ergo, allows for multiple hand positions when riding in the drops. This provides comfortable hand positions for riders who like to reach down to the drops, as well as for riders who reach in. The bar’s 70mm reach (the horizontal distance from the bar’s stem clamp area to the center of the brake perch) is the shortest of Zipp’s Service Course lineup. Its 128mm drop (vertical distance from bar’s stem clamp area to bottom of drops) places the rider low and in control without compromising comfort.

The SL-70’s round top provides a classic road-bar feel and is clip-on compatible.

A 10° ramp angle provides a perfect transition from bars to hoods, and the bar is also drilled to accept the Di2® RS910 junction. The SL-70’s round top provides a classic road-bar feel and is clip-on compatible.
