The new ERGOSUM PRO is a triple-butted Al 7075 T6 bar. ERGOSUM is shallower than ROTUNDO, and its shape suits smaller hands better. We redesigned the bend with a tighter radius where the brake lever sits, so you can adjust the angle of your handhold on the hoods easily without moving the lever far in either direction. We liked this feature so much, we gave it a name: QuickBend. Below the levers, the transition to the bottom of the bars is gradual, so it's comfortable to get hold of anywhere along its length - unlike many bars styled anatomic'.
