Cannondale is one of the most prominent bike manufacturers in the world. They also produce one of the most interesting and innovative suspension designs on the MTB market today.
The Cannondale Lefty fork has long been an enigma in mountain biking. It may look weird to the uninitiated but those who have used it often rave about its performance. While the Lefty tubes are round on the outside, internally the inner and outer tubes are machined square. This creates a hugely dynamic and smooth moving fork.
The hub has a huge 25mm bearing on the non-drive side that tapers to 15mm and mates up with Lefty’s one-piece tapered axle/lower leg. It’s also a one-piece design: unlike conventional forks with a threaded junction, the Lefty’s axle is directly attached to the lower tube. This creates one of the stiffest, most rigid MTB forks you can buy.
