2014 WHEELER SSP+ System
Since Wheeler developed the first edition ‘Super Single Pivot’ technology in 2009, we have been refining it ever since. In 2014, Wheeler has brought out an advanced solution to enhance the performance of the previous SSP system, called it the SSP+ (Super Single Pivot Plus). In the new SSP+ System, we offer a maximum balance in stiffness, tuned compliance and straight up performance during the MTB experience.
The bottom bracket of front triangle and the rotation axis of back triangle are mounted onto a common axis. This special construction has bound the rear wheel and bottom bracket together into one piece, delivering a direct driving performance. This design has resolved frame deflection due to pedaling motion, happens on most other bike frame design and providing best pedaling efficiency during suspension lockout.
100% Synchronized Front Derailleur
Under severe off-road riding, the 100% synchronized movement has maximized long-term durability and performance of the front & back derailleur and on chain, unlike the conventional fixed derailleur design. In order to prevent abrasive wear of derailleur, that usually happens on a Full Suspension MTB, the front derailleur is now designed to operate along with the rear wheel movement, making sure that the derailleur angle remains unchanged.
Unchanged Rear Center
The distance between the crank axle and the rear axle remains unchanged throughout the pedaling and suspension movement. In this way, factors such as Pedal Kickback (due to chain growth) and Pedal Bob can be resolved.
Maximized Shock Absorption
In the SSP+, we have repositioned the rear shock to mount on the top tube to improve sinking under weight pressure issue. Also, the center of gravity is directly connected to the specially design bottom bracket. This has enhanced the shock absorption capability and prevents different types of interference, providing a more stable riding experience than the first addition SSP.
This uniquely designed structure provides an exceptional rigidity to the lightweight bike frame. The coaxial triangles on the frame are built as a strong structure to handle a variety of loaded stress during severe off- road riding, and having the best torsion strength on frame
