Simply put, the Free Radical is a revolution in hard tail design and brings a new understanding to hard tail frames designed to work in the most varied and severe terrain. Further tweaked during 2006, the Free Radical frame comes equipped with the most progressive geometry available for a technical hard tail frame.

Start with our 1.5" head tube able to run any fork on the market up to 203mm (8") in travel and continue with massive tire clearance for the biggest 26" tires, ample stand-over height, and adjustable chain stay length for ride tuning or single speeding. Then, add ISCG05 chain guide tabs and 83mm BB width for easy chain guide mounting, and our innovative convertible rear wheel geometry correction for 24" or 26" rear wheels.

The Free Radical incorporates the most progressive and advanced long travel front end geometry designed for the steeps in addition to Knolly's trademark layback seat tube for extra "behind the seat" room while riding the serious stuff yet still offering a proper climbing position.

Now take all these features and put them in a solid North American made package fabricated to our exacting quality standards. Evolution? We think it's a revolution.
