On today's road bikes, silver stands out amid the sea of stealthy black color schemes. This time-honored handlebar color is available on the Zipp Service Course 70 XPLR, our newest drop-bar offering. The bar's moniker, XPLR, exemplifies the desire to explore the world with an expanded definition of cycling on a drop bar bicycle — from paved roads to gravel, mud, dirt, and even singletrack. The Service Course 70 XPLR helps you go faster by placing your body, starting with your hands, in an optimal "comfort zone" position for hours of rough riding over mixed terrain. Whether on a two-hour training ride from home or a 200-mile gravel adventure, today's riders demand more of their cockpit: comfort, control, and the ability to carry what they need. We met these needs by creating a bar with shallow and wide drops while focusing on two crucial metrics — outsweep and flare. - Bar drops provide a wider, balanced, and secure position with drops that are about 6cm wider than the hoods position for technical or intense riding. - The 70 XPLR features an ergonomic top with an extended 100mm clamping area for computer mounts, aero-extensions, bags, and whatever else you may need for the long haul. - Reach: 70mm - Drop: 115mm

The bar's 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 their optimal position. - Distinctive Zipp cosmetics - 7050 aluminum for light weight and durability - 70mm reach and 128mm drop for a short-low position - Flattened top shape with 3° backsweep for comfort - Clip-on Compatible (40, 42, 44cm sizes only) - Lifetime warranty

Together with its 128mm drop, the bar is deal for riders preferring a low body position. Whether it's a rider with a shorter torso or a bigger rider getting aero by pairing this bar with a long stem, this bar helps put just about any cyclists into their optimal position.

Multiple hand positions are key for comfort and confidence on any ride, and the Classic VentureMax offers plenty of options there—especially with its wide 24-degree flare at the drops.

The evolution of Ritchey handlebars continues with the Comp ErgoMax. This new bar enjoys a rich history of handlebar design and development and combines it with the modern demands of discerning riders who enjoy riding varying surfaces. Designed to enhance control and comfort when riding along loose surfaces, the ErgoMax is ideal for a gravel bike since it places the hands in a wider, more stable position while in the drops.

The bar tops employ a 10mm rise at the clamping area, which offers a slightly more upright riding position.

Continuing with an eye towards ergonomics, the ErgoMax also features drops with a nice 12-degree flare to keep the rider's hands in a comfortable and confident position, while also adding a bit more unobstructed stability when turning or sprinting.
