The new system is called 2Spring and will be used on all new Lefty forks. It will be available as a free upgrade for all cyclists with Lefty forks using the Solo Air system's wave spring or coil upgrade. Lefty forks from 2013 to 2016 are eligible for a free upgrade.

To ensure that 2Spring doesn't take a hit, Cannondale says it has gone to great lengths: The test cycles and strength specifications were tripled so that they now far exceeded any industry standard. For the ride tests, Cannondale used 50 of the most trusted riders and technicians in eight countries on four continents to eliminate potential performance variations due to parts, installation or riding conditions. Further confirmation comes from Cannondale race teams with Leftys, who have been successfully using the 2Spring system for months. 2Spring is not another remedial measure, it is a leap forward in terms of ride quality, performance and durability, announces the US manufacturer.

2Spring is named after the self-balancing positive and negative air springs, which are controlled by two coiled valve and top-out springs and are designed to provide a massive boost in performance and reliability. The advantages of the system are a freer movement of the fork in the upper spring travel and the use of fewer parts, which increases reliability and reduces weight. By changing the air piston geometry, the piston presses more oil against the seals, which makes the fork work more smoothly. The service intervals at 2Spring are also more generous, meaning that the leftys no longer have to be serviced every 100 hours.
