Cyclocross bikes are uniquely designed for the sport; a good cyclocross bike can definitely help improve your lap times, and make racing and riding that much more enjoyable.
Having a cyclocross bike to race can be helpful, but it is not required
to participate in the Sacramento Cyclocross series! Racing on a mountain bike is fine in most categories. Here's the rundown: For Elite A, Master A, Open Master and Open Singlespeed categories, bike tire width must be 40mm or less and bikes may not have suspension. For all categories, flat bars are allowed without bar ends. No forward facing bars. No spiked or studded tires. No fixed gear hubs. No power assist (no duh!).
