Calvin entered the world of two-wheels at a young age; a typical weekend for Calvin consisted of traveling to compete in either a BMX race or a Freestyle BMX competition. Following his years racing and competing in BMX, Calvin took up motocross racing. As time went on, the expense and time commitment of racing moto led Calvin to search for more affordable and accessible excitement.

Calvin found mountain biking roughly a year ago and has yet to look back. Why would he, as plentiful trail access had him hooked, and his skills learned from BMX and Motocross had him ripping! You’ll find Calvin racing throughout 2018 at various stops of the California Enduro Series.

About the bike: 

Since Calvin’s gasoline-powered history made him comfortable riding at high speed, he wanted a bike that could handle anything he’d throw at it while still performing well on the climbs. Calvin’s Pivot Firebird Pro XTR/XT build comes stock with Shimano’s workhorse XT group, and Fox’s X2 shock and 36 fork—ready to race right out of the box.
