The sprinters choice. PRO engineers team up with the Cav and design a flex-free and problem-free solution for the ultimate hardman's handlebar. Mixing it up in tight quarters in the P1/2 field during a sprint or not snapping in half during a Cat 3 pile up, this bar is any racers choice if lightweight is not a top order.The top of the bar has the now familiar Top OS, meaning the top of the bar has a sustained 31.8mm diameter, not just a bulge at the stem clamping area. Semi deep drops with long flat sections for your hands in the drops will increase stability (and confidence) during sparring sessions. Heat treated 7075 alloy is bead blasted and anodized black for added durability and good looks. Graphics are simple and almost understated for such a stout bar. Hash marks indicate were to accurately place both your brake/shift levers and stem. These bars are measured center to center and available in 3 widths. Industry standard 31.8mm clamp diameter only.
