Zipp SL V2 Bars Shallow Bend - A minimalist bar for climbers and smaller riders, the Zipp SL Short/Shallow Carbon Bar is the result of over 4 years of research and development and more than 40 revisions of the carbon laminate structure. - It weighs a mere 170g (SS drops, 42cm o-o), but it's stiff enough to grunt over the steepest grades and smooth enough for all-day comfort, thanks to Zipp's VCLC vibration-damping technology included in all their bars. - Features like dual cable routing grooves and a gradual taper from 31.8mm at the clamp to 24.2mm at the bends contribute to the SL's classic looks. - The goal was to design the lightest drop bar available while still passing EFBe Laboratory's top performance racing standard. Zipp achieved it with the SL. - Weight (SS 42 cm) 170g.
