When it comes to handlebars, tried and true aluminium remains the material of choice for many pros. In part, that’s because their bikes have to meet a minimum weight requirement.
But it also means that aluminium bars like the Service Course SL have to meet the fit, durability, and performance standards of athletes like US cyclocross champion Tim Johnson and the Cannondale Cyclocross Team prepared by CyclocrossWorld.
The Service Course SL is produced using Zipp's proprietary ZTL-71 alloy and intricate internal butting processes to achieve a weight of 280g (42cm) with superior strength and rigidity. It features a classic look with round cross-sections throughout and is available in the same, comfortable Short & Shallow or Traditional Bend shapes as their carbon bars. The drops are angled outward by 2° to reduce wrist strain.
Road bars are curved to offer a multitude of positions to suit the terrain. When climbing in the saddle you will often ride on the tops which are the part of the bar either side of the stems clamping point. When out of the saddle on climbs or accelerating you will often ride on the lever hoods mounted at the front of the bars curved section. For higher speeds you will find yourself on the drops, which offer a lower more aerodynamic position. Road bars come in a variety of widths, from 36cm wide up to 44cm, a good guide for bar width is your shoulder width, a bar should not be narrower than your shoulders as this can close up your chest, but they should not be so wide that you are creating a large frontal area. Road handlebars come in two clamp sizes, 31.8mm which is oversized and 26/25.8mm which is standard, it is essential that you get the correct clamp size for your stem as a poor fit will slip round. Road bars also come in different shapes and depths, with various bends for ergonomic reasons, some will also feature grooves in the material for your brake and gear cables to slot into, this helps to keep the bar round once tape is applied. Then there is the all-in-one bar and stem systems from brands such as Cinelli's Ram 2 and the Pro Stealth which offer clean lines and look great with their exposed carbon finish.
