Dawes Mountain Bike – Watoga 26′ wheels, medium frame, RST 381. Thank you for looking at my item. Sadly I know nothing about bikes so I have photographed every bit of information that is on the bike for you to see. Hopefully this will answer all your technical questions. But I can tell you it is a great bike to ride, it is in excellent used condition, all parts are working and it belonged to my partner who is wanting to sell.
