An early adopter of aluminum in the construction of lightweight, durable mountain bikes, Charlie Cunningham also fabricated a number of the components used on his bikes. This particular model features such originals as Rollercam brakes, modified Hi-E hubs with an early Grease Guard fittings, toe cage flips, a custom high-rise stem, on the fly cable tension adjusters, and hand-lathed seatpost QR and cable stops. Did I mention this bike has dirt drops? Check out the carefully re-shaped Cinelli road bars. These are the precursor to the off-the-peg WTB dirt drops you'd see in later years. Add in the magnificent original
Steve Potts Charlie Cunningham original (thanks for the clarification @singletracktourist) fork and this is probably one of the most pristine examples of his early work.
