Potomac Vintage Riders sponsors the 10 round AHRMA Mid-Atlantic region Vintage and Post Vintage Cross Country series. Vintage is for bikes built typically before 1975 and Post-Vintage is for bikes built from 1975 – 1988. There are also Disk Brake (Pre-Modern, Early-Modern, etc.) classes up to 1999.
See race flyers at www.ahrmaMA.org for more specifics on bike eligibility as brake type, suspension travel and bike year all play into it.
All classes are further divided into AA, Expert, Intermediate and Novice skill levels. Courses are usually 3.5 – 5.0 miles long and offer a wide range of challenging trail conditions from woods single track, mud/rocks/roots, hills, grass track and two-track logging/fire roads.
