This Vintage Trek Singletrack 930 Mountain Bike in black forest green with gold decals, and an 18" frame, is a classic mountain bike made with True Temper chromoly steel. Made in the USA, it features 21-speed derailleur gears, Rapidfire thumb shifters, cantilever brakes, and an adjustable seat. The bike needs a tune-up—headset and rear wheel hub are loose—but otherwise is in good shape. There’s also a third wheel fitted with a mountain tire to swap out if you want to take it on the trails. Currently, the front wheel on the bike is fitted with a smoother tread tire for street biking.
