Knolly’s motto is “Reliable Predictable Performance.” That philosophy goes into every frame design and finished product.

FASTENERS: Knolly only uses high-end name brand fasteners ensuring that their fastener products are consistent and reliable. All fasteners are stainless steel and where required, super hard grade 12.9 plated steel. Knolly does this to ensure that the fasteners don't corrode and don't bend. In addiiton, Knolly uses M8 bolts for all of our shock mounting hardware on our heavier duty frames, again from a strength perspective. And, wherever possible, they use commonly available metric fasteners so that they are easily replaced if damaged or lost.

PIVOTS: All pivots feature German INA brand bearings and most use precision machined stainless steel shaft spacers to achieve tight tolerances. INA brand bearings feature some of the most consistent race diameters available, especially important in locations under high lateral load like suspension rocker linkages. Their consistent diameters mean less chance of bearings wearing out their “seats” (the bore that the bearing sits in) resulting in less down time for you the owner.The two main frame pivots use a pair of INA double row angular contact bearings combined with oversized axles resulting in superior lateral rigidity and high load carrying capability. Pivot bearings are spaced as wide as possible to further increase rear end stiffness.

AXLES: Knolly's axles and shoulder bushings are CNC turned out of 2024 aluminum for high strength. Rear thru axles feature a stepped outer diameter which guarantees precision where the axle supports the hub bearings. Chain stay pivot axles and rear axles are deeply broached for large 8mm hex keys to make them highly resistant to stripping.



MACHINING: CNC (Computer Numerically Controlled) manufacturing is something that Knolly take great pride in. Knolly routinely machine parts to within 0.001" (0.02mm) tolerance; for bearing seats often to a very precise 0.00025" (0.006mm). Why would they spend the time and energy to do this? Quite simply, it allows Knolly to design and build features like the V-tach's head angle adjuster cam as well as improve the functionality and reliability of their products.

WELDING: All frames are welded to the highest standards. Welding is probably the single most important part of frame construction — technique can make or break the best designs. In keeping with Knolly's design philosophies they only use the best available bicycle frame welders, ensuring that welding is not only performed correctly but is aesthetically pleasing as well.



The Four by 4 Linkage is Knolly Bikes' patented and proprietary suspension technology. Their 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
