The Four by 4 Linkage.

The Four by 4 Linkage is Knolly Bikes’ patented and proprietary suspension technology. Our suspension design is akin to the most sophisticated multi-linkage systems used in auto racing and provides features and performance unmatched in the mountain bike industry.

Knolly designs and manufactures two versions of its Four by 4 Linkage: both designs are patented but are aimed at slightly different market segments:

The original design is used in the Podium and Delirium frames and is optimized for the generally more linear rates of coil spring suspension and long travel high volume air shocks. This design also provides a slightly higher leverage ratio typical of longer travel frames and is designed structurally to handle the highest levels of abuse. It also generates the large radius wheel paths required to achieve superior pedaling performance in longer travel frames while still having incredible sensitivity for amazing technical trail performance.

The lightweight Four by 4 Linkage is used in the Chilcotin and Endorphin frames. Its design is tailored to the slightly more progressive spring rates of high volume air shocks and has a direct-drive linkage that compliments the lower leverage ratios used in these bikes. It is also more compact and while allowing the use of relatively long stroke shocks still leaves lots of room in the front triangle for both great stand over height and the ability to carry a water bottle in an actually useful location. The lightweight Four by 4 Linkage provides superior traction allowing for exceptional technical climbing and descending abilities in all gear ratios, yet achieves the best pedaling performance capable in any suspension design.

All of our full suspension frames utilize the patented Four by 4 Linkage design: whether the original or the lightweight design, all Knolly Bikes frames feature amazing pedaling dynamics, superiour traction, great tire clearance, extremely high lateral rigidity for excellent trail tracking, neutral braking forces, great stand over, full length seat tubes, easy to access rear shocks and low maintenance designs. The Knolly Four by 4 Linkage is simply the most sophisticated, highest performance design available in the mountain bike industry – period.
