| Features | CVA IS PATENTED (U.S. Patent No. 7,934,739)
CVA is a unique, award-winning suspension design and has been recognized with a US Patent.
CVA IS THE ONLY 29er SPECIFIC SUSPENSION DESIGN
CVA is the only suspension designed to take advantage of the increased bottom bracket drop of 29ers.
CVA OFFERS EFFICIENT PEDALING IN ALL CHAINRINGS
Because the lower swingarm linkage is located underneath the bottom bracket, chain torque in any chainring effectively neutralizes the unwanted forces that degrade power transfer to the rear wheel.
CVA IS POSITIVELY REVIEWED AROUND THE WORLD
CVA-equipped Niners have earned praise from riders in online forums and magazines all over the globe.
Although CVA resembles some of the other parallel link designs, CVA works very differently to isolate pedaling forces and remain fully active under all conditions. Many current suspension designs, especially some parallel link suspension designs, maximize efficiency by anticipating that most of your pedaling will be done in the middle chainring and are designed around this ‘virtual’ pivot location. This means that there is some compromise to the suspension’s pedalability when NOT in the middle chainring or when using a 2x10 set up. The better the design, the less noticeable this compromise is.
In order to isolate pedaling forces across a broader range of gearing, the CVA’s ‘instant center’ location is in front of the drivetrain. With the lower pivot under the bottom bracket, the force at the rear axle resulting from chain tension pulls the two linkages in opposite directions in all gear choices, effectively isolating the drivetrain from the rear triangle. In other words, when a rider cranks on the pedals, the chain is trying to pull the lower link down and away from the bottom bracket, and the upper link in its regular rotational path. Since the rear triangle is one piece, these opposing forces cancel each other out, leaving the only outlet for chain-induced torque being rotation of the rear wheel, where it’s most wanted.
Past the rearward-most position at sag, the axle path moves in towards the bike at a gradual, constantly varying arc, which insures that there is minimal chain growth throughout the length of travel. This also means minimal pedal feed back in the drivetrain while cycling the suspension, essentially isolating it from the fully active movement of the suspension design.
Ultimately, there are many variables in suspension – we believe that we have created a strong, 29er specific system, and that the best way to test it is to go out and ride a Niner full suspension bike. |
