When the racing gets serious, the serious get racing aboard a 1991 Haro Group 1b. The same frame for geometry as our national champ 1a. Same sleek rear monostay. Same trick, calibrated dropouts and brazed-on cable guides. Even the same exotic tapered 4130 aircraft chromoly forks. Add ACS braking, Araya rims, Haro Holeshot racing tires and Fusion forged-alloy stem for a winning combination.
