2011 Lefty Headshock Forks - Travel Changes and New Rockshox Bits
For 2011, Cannondale seriously revamped their Lefty forks. Travel has changed for both the Speed and 29er models, and they’ve partnered with Rockshox to develop new compression and suspension settings to accommodate users that felt older models were too soft.
With Lefty, you’re getting a 1.5″ headtube, a 25mm-to-15mm axle and dual-crown design, all of which Cannondale says makes for a far stiffer fork than traditional forks with two legs. They also say it’s smoother: Its square stanchion with needle bearings creates a mechanical movement rather than bushings that can wear and develop play and have far more friction. The roller bearings also maintain smoother movement under rotational and off-angle forces…which could better control and traction under hard braking and corning. In our test ride on the new Scalpel, despite having reduced travel, the Lefty fork did handle XC-type trail bumps, rocks and chatter with aplomb. The older, “softer” models made the forks feel incredibly smooth in parking lot tests, but enough riders complained that they would blow through their travel too quickly on the trail. To remedy this, the compression damping is firmer all around, which makes them feel slightly less smooth when just pushing on them standing still, but the results seemed to justify the means.
There are two versions of Lefty available, PBR and XLR. Check them out with specs and weights after the break…
