The same compact reach and drop dimensions as the Service Course SL-70 with a flattened top section for a natural ergonomic grip on the bar tops. A revised ramp angle for proper fit. The SL-70 Ergo’s specially tuned drop shape creates comfortable hand positions with short reach to control levers vital for race situations. The bar’s 70mm reach is the shortest of Zipp’s new Service Course lineup. Its 128mm drop help puts the rider low and in control without compromising comfort. Whether it’s a rider with smaller hands or a bigger rider getting aero by pairing this bar with a long stem, this bar helps put just about any cyclists into his or her optimal position. Four sizes. 7050 aluminum. High Polish Black with white logos or Beyond Black.
