were not standing up to the rigors of mountain biking. Breeze was asked by Charlie Kelly to build a mountain bike frame and in early 1977 Breeze agreed to do so. While working on the design for the mountain bike, Breeze took orders to make mountain bikes for several other Marin County off-road cycling enthusiasts. He completed the prototype (Breezer #1) in Fall 1977 and rode it to victory at Repack. Breeze finished nine more Breezer mountain bikes by June 1978. He built up the bikes with all-new parts, which he sourced from around the world. Those ten Breezer Series 1 bikes, made of chrome-moly alloy steel, are widely considered the first modern mountain bikes. The first ten Breezer mountain bikes can be recognized by their twin lateral tubes, which Breeze included to stiffen the long frames for high-speed tracking. Breeze revised his designs shortly after, and shared his ideas for the next generation of mountain bikes with other framebuilders, including Tom Ritchey (of Palo Alto, 50 miles south of Marin) who built his first mountain bike frames in 1979. Ritchey became the frame supplier to the Marin County company MountainBikes, founded in 1979 by Gary Fisher and Charlie Kelly. The mountain bike's progression from local San Francisco Bay Area builders to the larger industry was complete in Fall 1981, when Specialized Bicycle Components introduced a lower-priced production mountain bike, the Specialized Stumpjumper, built in Japan and based on the Ritchey-built bikes sold by Fisher and Kelly. Early mountain bike racing, events Joe Breeze raced in 19 of the 24 Repack races, winning 10 times. Twenty-two of the Repack races, downhill time trials organized and promoted by Charlie Kelly, were held from 1976 to 1979. Repack is known as mountain biking's first recorded competition. The last Repack race in 1979 was filmed by a TV crew for a San Francisco Bay Area news program, KPIX Evening Magazine. That filmed account aired nationally, spreading the word about mountain biking to a larger audience. The Repack race was revived for two more runs, in 1983 and 1984, becoming the first officially sanctioned downhill mountain bike race. A mosaic tribute to Repack was installed in downtown Fairfax in 2013. In 1978, Joe Breeze was one of five riders from Marin County to travel to Crested Butte, Colorado, to participate in the Pearl Pass Tour, a two-day, off-road ride from Crested Butte to Aspen,
