Cannondale has made the single-legged Lefty LFA (Lefty For All) PBR140 Suspension Fork available for 2011. By using a fixed tapered axle and a keyed design, the telescopic single leg allows for an excellent on-trail steering and braking rigidity at an extremely low weight.
While it is compatible with 1.125 and 1.5in head tubes, the offset fork calls for a dedicated wheel. Moreover, although having to loosen the brake when removing the wheel and the left knee clearance out of the saddle hassle, the wheel in-situ can fix the punctures.
Providing the the 140mm RockShox-derived air spring stroke a flexible ground-tracking start are the 88 needle bearings. The 2011 Cannondale Lefty LFA PBR140 Suspension Fork offers a consistent PBR damping controlled with a presson, snap-off lockout/rebound adjuster beneath bar level.
