Jag satt och läste om det tidigare idag. Horst länk skall tydligen vara helt imun mot brake jack. Och om jag förstod det rätt så var syftet det för KarlHeinz Nicolai exjobb. Sedan att den råkade bli trampeffektiv också är ju inte helt fel. Hittade nedaståen bl a.:
"4 BAR LINKAGE DESIGNS: AKA HORST LINK
There’s never been a more hotly contested suspension design on the market then the 4-Bar linkage design with the Horst Link. This design has been around only slightly longer then the original Outland VPP, but its instant success and many attributes have made it the most valued and fought over suspension design in the world. The original design was developed by Horst Leitner at AMP research. The driving goal behind the design was to isolate braking forces from affecting the suspension performance. The first generation Horst bikes did not stiffen up or lift (brake jack) under hard braking. They were and still are to this day “fully active”. The icing on the cake was that the original bikes pedaled better then anything else at the time.
The original Horst patents were purchased by Specialized Bicycles and are selectively licensed to only a few companies in the USA. In Europe and Canada where the US patents don’t apply, Horst Link style bikes are the dominant suspension design. Just like with virtual pivots, and floating bottom bracket designs, many of today’s 4 bar designs are at least 3 generations beyond the original. Everything has been changed to make the already great pedaling design even better without affecting the bike’s excellent performance under braking. Four bar bikes, are light, strong and can be built extremely stiff without the complexity and issues associated with other suspension designs, plus they don’t stiffen up under braking. If you own a suspension bike, you want the suspension to work. One of the worst traits a suspension bike can exhibit is to have the shock get progressively more locked out as you are braking hard into a bump filled corner. This is when you need the suspension most and this is just one of the areas where the 4 bar delivers and others can’t.
So what’s the downside? There is almost nothing bad that can be said about a well made 4-bar design. However, nothing is perfect. Because of the way the suspension works, long travel 4 bar bikes frequently need to have an interrupted seat tube design to the front triangle. Although there is no performance or handling downside to this, some riders prefer the traditional look of a standard front triangle and/or like to have the wider range of seat post adjustment of non-interrupted seat tube bikes.
Bottom Line: Current 4-bar designs from high end companies have the edge over anything else on the market. The ability to build light, class leading bikes at any travel range with ample tire clearance, great pedaling feel, in a fully active chassis with the highest level of durability is a combination that cannot currently be matched by any of the competing designs on the market.
