Founder of Redline Bicycles. As an early manufacturer of suspension frames for flat tracks and TT racer motorcycle frames, Linn introduced ideas that raised the of technology in BMX to new levels--namely, the use of 4130 chromoly tubing. Inventor of the first tubular chromoly fork--in 1975 and in 1980, Flight Cranks, the first tubular chromly three piece crankset. The mid-80’s saw Linn bring a change to the look of forks (just as he did in the 70’s), with the introduction of the Kastan Strut (one-legged) fork. Today, Linn owns and runs Redline Aviation.
