Rare AMP RESEARCH Steel Fork 1 1/8” 63mm Retro Mountain Bike Fit Ibis Yeti Moots
Item History & Price
Very hard to find Amp Research 1993 F1 fork. 1 1/8” Threadless steerer, 9mm quick release. Fork is surprisingly light for the legs being steel. But they are hollow and open on the end. Fork is a four bar design and still works perfectly. Steerer tube is 7.5” long and will work well with most small to medium bikes. It also was compatible with my large Merlin frame so it really just depends your Headtube length and headset stack height.
This compact F1 linkage fork is still a bit ...of a marvel today. Horst designed it to emulate the axle path of a telescopic fork, while keeping all the moving bits up top, so he could still use cable-operated rim-brakes. The fork was suspended by a stiff steel spring tucked under steerer tube, while damping was handled by a pair of impossibly small through-shaft shocks, pinned to the sides of the linkage arms.
Some info on Horst Leitner and amp research:The AMP B2 is unique among mountain bikes because every aspect of its frame, fork, and suspension was designed and manufactured by AMP Research in Laguna Beach, California.
This story begins with a young engineer and motocross racer who left his home in Austria to set up shop in the Unites States. He founded AMP Research and among his many endeavors, he invented a motorcycle rear suspension that removed braking and acceleration torque from the suspension action, which led him to design and manufacture ATK motorcycles in the 1980s - one of the first competitive four-stroke motocross racing bikes.Most of us, however, know of him in reference to the "Horst Link" dropout, which is ubiquitous today, but was an important invention in the early 1990s, when dual-suspension mountain bikes were in their infancy.By 1993, Horst Leitner was still racing motocross every week, but his new passion was riding mountain bikes on the trails near his Laguna Beach home. It didn't take long for the inventor to come up with an improved mountain bike. Initially, Horst developed a simple rear suspension for Specialized, and it marked the brand's entry into the dual-suspension arena - well, kind of.Leitner was convinced that rear suspension was going to revolutionize the sport, and quickly became frustrated with the boys at Specialized, who, in his words, "Seemed like they wanted to make a suspension bike, but were screwing around and going nowhere." Patience is not one of Leitner's virtues, so before long, he had assembled a small factory that began churning out aluminum-framed dual-suspension bikes, the likes of which, the bicycle industry had never seen before.
This fork is from an original B2
Any questions?, feel free to ask :)
Good luck winning and happy bidding!
