What dimensions do the Cannondale Lefty forks have in the axle area and where do they fit?
In general, the axle mount has always remained the same - only the offset of the axle has changed to 2.0/Supermax
The Lefty 50 hub fits Lefty bellows, hybrid 1.0-2.0 and Supermax
The designation here 50 refers to the flange distance = 50mm
The Lefty 60 hub only on the hybrid 2.0/Supermax and Ocho
The Lefty hub 73 is exclusively for the so-called fat bike lefty Olaf.
