The fact that Campagnolo only made a few very small teaks in these levers over version 1 gives us an idea of how close to perfect the original 11 speed design was for an ErgoLever. The carbon body has a new resin formula which decreases weight and adds a bit of strength. While improving the body, they also changed the routing path of the cables to decrease the bulge that occurs under the hood where the cable housing exits the lever. The ratchet wheel inside the rear shifter also receives a small re-profiling to make the shifting have a 'lighter feel'. Probably the most obvious change is the graphics. The outer shift blade has the modern Chorus 11 graphics to match the rest of the group. Small improvements - yes, but worthy of mention. All else remains the same.
The hoods have what Campagnolo refers to as VariCushion which has dual density rubber for excellent ergonomics and grip. On the subject of ergonomics - The levers come with one pair of inserts to adjust the length for larger hands. The long shift blades have dual bends which offer a multitude of hand hold options and plenty of leverage for shifting and braking.
All of the shifting mechanisms reside on a bearing, not a bushing for smooth operation and longevity. As with all ErgoLevers, they are completely serviceable with replaceable parts. Shifter levers include on full cableset for brake and shift with end caps and ferrules.
