Doc Wong’s Riding Position and Ergonomics workshop. All Doc Wong clinics are educational, fun, and free and put on Doctor Harry Wong. Night classes take place in Doc Wong’s Redwood City office, and Sunday rides start at the office with a talk and are followed by a four hour ride through the hills. The Doc requests that you email him or call his office to let them know you will be attending a session, and we recommend checking his website as well for further information on his different classes. Confirm by emailing email@example.com or calling 650-365-7775.
