LIGHTER
Lefty's minimalist single-leg design lets it be lighter than most competitors’ lightest XC race forks.
Stronger
Lefty's dual crowns and oversize inverted structure give it such strength that even the lightest Lefty can out-perform burly all-mountain forks in destructive testing.
Stiffer
Lefty’s stout structure, combined with its "square-in-a square"stanchion design and lower glide bearing make it torsionally stiffer than any fork in the world, for pinpoint steering precision.
Smoother
The heart of the Lefty, Cannondale’s patented hybrid needle-bearing technology keeps the suspension moving freely, regardless of load. Even under the hardest braking, impact, and steering forces, the wheel is able to track the ground fluidly for maximum control.
Worry-Free
The new hybrid design allows the entire fork structure to be completely sealed against the elements for long service life and features auto-resetting needle bearings to eliminate the need for regular manual resets.
Key Lefty Technology
Dual Crown Inverted Design
With the larger, stiffer fork tube on top where it can more effectively fight flex and add strength, and dual crowns connecting it solidly to the headtube, the Lefty's unconventional design is simply the lightest, stiffest, strongest way to build a fork.
Square-in-Square Design
The needle bearing races form a square-in-square interface between the inner and outer fork legs, preventing the two tubes from rotating relative to each other like the round-in-round design of traditional forks. Contributes to Lefty’s incredibly stiff and precise handling.
Hybrid Needle Bearing System
Friction-free needle bearings provide unmatchably smooth suspension under all loads, while the lower glide bearing provides additional support for improved stiffness and steering precision as the fork moves through its travel.
Durathon Sealing System
A comprehensive internal and external sealing system keeps the good stuff in and the bad stuff out, allowing for more than double the time between recommended services than our competition.
SUPERMAX 29’ER
Lefty goes BIG.
The all-new SuperMax takes everything that makes Lefty great and supersizes it. The result: a fork as stiff and strong as most dual-crown DH forks, yet lighter than most all-mountain forks. Just the thing for longer-travel 29’ers.
MASSIVELY OVERSIZED
The SuperMax’s lower leg is 36mm in diameter, while the upper leg measures a whopping 46mm for maximum stiffness and steering precision.
SHORT STEM COMPATIBLE
To accommodate current trail riding set-ups, an offset axle allows the fork leg to sit further back, creating enough clearance to run stems as short as 50mm.
MULTIPLE SIZES
To ensure that riders can achieve the best fit on long travel 29’ers, the SuperMax is offered with multiple crown spacings to fit different headtube lengths.
WIDE FLANGE HUB
The new SuperMax Lefty hub features wider flange spacing which allows increased spoke angle for a stronger, stiffer wheel.
