In part, that’s because their bikes have to meet a minimum weight requirement, so there’s little reason to use a sub-200g carbon fiber bar like the Zipp SL. But it also means that aluminum 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 our proprietary ZTL-71 alloy and intricate internal butting processes to achieve a weight of 260g (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 our carbon bars. The drops are angled outward by 2° to reduce wrist strain.
