Every aspect of the bars performance has been reviewed in the light of 4 years experience of top-level racing. Elbow-rest supports now fit into a recess on the top skin of the basebar so they can’t skew out of true. The handhold & grips, which in some conditions could slip on the handholds, are replaced. Shimano Di 2 compatibility is introduced. As before, a full range of adjustment optimizes rider position. The extension bars adjust front-rear for reach, & vertically for height. Elbow pads move with the extensions, preserving a constant relationship between hands & elbows. The standard straight carbon-fiber extensions can be swapped for S-bend or ski-bend extensions, for a perfect custom fit for champion athletes of every physique. VENTUS II continues to set the standard by which all other triathlon aerobars are judged.
