Regardless of its renowned homage to carbon, Zipp realizes that aluminum is far from an outdated material. Whether you prefer it for peace of mind in the heat of the sprint or find the slight weight difference an easy way to keep your ultra light bike above legal weight limits for your Cat 1 debut, the Zipp Service Course SL Ergo Handlebar showcases the best of aluminum's qualities strength, low weight, and relatively low cost. The Zipp SL Ergo handlebars are the replacement for the Zipp CSL bars. They were designed with Zipp's SSR Super Short Reach dimensions a 70mm reach means that it is easier for riders with shorter arms and smaller hands to reach the shifters while in the drops. These dimensions are the same as the SL 70 the primary difference is that the tops of the SL Ergo bars have been sculpted flat to provide a substantial platform for your hands during long climbs. The cables tuck nicely underneath. The drop angle of the bars is only 20 degrees. This allows you to position your levers in the 'high and Belgian' style or in the flat top neo pro style without having to rotate your bars skyward. The drops have a 2 degree outward bend for more wrist comfort, which also minimizes bruised forearms while sprinting. The Zipp Service Course SL Ergo Handlebars are available in 2cm increments from 38cm 44cm measured center to center, and each pair of bars fits a 31. 8mm stem. They come in two colors: Polished Black, a high gloss finish with white logos, or Beyond Black, a matte black with etched logos for a stealthy look.
