Handlebar shape affects more than hand position—it determines how your bike handles in the drops, how comfortably you can brake from the hoods, and whether your wrists stay happy after four hours in the saddle. The Zipp Service Course SL-70 Ergo takes the ergonomic drop design that's become standard on professional-level bars and brings it to an aluminum construction that costs considerably less than carbon without the compliance penalty you might expect. The 70mm reach and 128mm drop dimensions place your hands in a modern, compact position that's become the default geometry for road racing and long-distance riding.

The ergo bend in the drops is where this bar earns its keep. Rather than a traditional round curve, the lower section flattens slightly where your palms rest during hard efforts, distributing pressure across a wider surface area. That flat section continues into the ramps leading to the hoods, giving you more usable real estate for hand positions on long climbs. The transition feels natural whether you're sprinting in the drops or soft-pedaling with your hands draped over the tops.

Zipp uses 7050 aluminum with a shot-peened finish that reduces stress risers in the material—the same surface treatment used on aerospace components to improve fatigue life. The 31.8mm clamp diameter fits standard oversized stems, and internal cable routing channels keep housing runs clean through the bar. Available in 38cm through 44cm widths measured center-to-center at the drops.... Read More
