I have 2 Trek mountain bikes. Model 7000 and Model 8000. Both for $500. They probably don't even have 40 miles on them. Still have the little rubber hairs on the tires. THEY WERE MADE IN THE USA. Trek bicycles are now made in China. They have aluminium frames with new helmets, mounted water bottles and they both have luggage carriers on the rear. Paid about $1700 for both plus helmets, water bottles and carriers. They are both equipped with Shimano hardware. They are still like new. Selling because we are in our 70's. Haven't rode them in years. You won't find any used bicycle in this perfect condition.
