The saga of the concentric pivot suspension system continues today, with Trek’s announcement that they have been awarded a US patent for their Active Braking Pivot rear suspension design, which attempts to effectively separate braking and suspension forces by using a concentric pivot around the rear axle.
Earlier this year, we reported HERE that Dave Weagle’s Split Pivot system had been awarded a US patent for a suspension system that used a concentric pivot around the axle, which may have appeared superficially similar to Trek’s ABP system.
There was speculation at the time about the implications of the Split Pivot patent on Trek’s use of ABP but we were told that Trek were well aware of Dave Weagle’s design and patent and would continue to manufacture ABP bikes. The award of the patent should put to rest any comment about ABP’s difference to Split Pivot.
Active Braking Pivot has been a feature on Trek’s range of bikes since 2007, and is currently found on eight Trek and Gary Fisher suspension platforms. Dave Weagle’s Split Pivot patent was also publicly launched in 2007 but only became available on bikes from a variety of manufacturers in 2010.
Trek say that the award of their patent has broad implications, as it “covers a concentric pivot in combination with much more sophisticated and varied types of rear suspension designs”.
Of course, in both patents the concentric pivot element is actually a small part of a much broader overall design that is patented – we suggest you have a look through the Split Pivot patent available on their website HERE. It’s not particularly light reading…
Invented by suspension engineers James Colegrove, Dylan Howes, and Jose Gonzalez, Trek say that the Active Braking Pivot patent is: “…further proof of Trek’s commitment to leading the world in mountain bike technology”
