I recently rode a bike designed by Daryl Funk of Denver Co. Funk designed bikes and built them under his name in the late 80's and early 90's. His latest titanium full suspension pivotless design is the stiffest and most rigid full suspension bike I have ever been on. At 250 lbs. I can flex about any bike, but not this one. 3.5 to 4 in. travel. A great bike especially for the hard tail enthusiast wanting full suspension. Check it out at www.285.us.
