Zipp Service Course 70 Ergo

The Ergo design features a flattened top section that provides a wider, more natural surface for your palms to rest on. This shape helps distribute pressure more evenly across your hands, which can significantly reduce fatigue during longer rides.

These bars use a standard 31.8 mm clamp diameter, which is the industry standard for almost all modern road bike stems. As long as your current stem is designed for 31.8 mm bars, they will be compatible.

The 70 mm reach and 128 mm drop are designed to make the transition between the hoods and the drops feel less aggressive. This geometry is ideal if you prefer a slightly more upright, accessible position rather than a deep, race-oriented tuck.

Yes, 6061 aluminum is a proven, robust material choice for handlebars. It offers a great balance of structural integrity and weight, making it a reliable, long-lasting option for daily training and road riding.

While these are specifically designed for road use, they are durable enough to handle light, smooth gravel paths. However, if you primarily ride rough gravel or mixed terrain, you might prefer a dedicated gravel bar with a wider flare for better control.
