I got the bike home and WOW! This thing is cherry! Only a few light scratches, still has the nubs on the top of the tires too. The thing had hardly been ridden, one thing the PO attested to. His son out grew it too fast and he needed a taller bike. The only real issue was the rubber wipers on the shock tubes had cracked and were on the verge of falling off. I saw the chain was dripping wet w/ oil too. I wiped it off real well and it looked like the guy hit it with some light oil before leaving the house. So no biggie.
I dropped the seat, adjusted the brake handles in, tweaked the front derailluier to stop the rubbing, and gave my son a quick lesson on the shifters. He had a hard time at first grasping the gear idea, until he went for the hill up the street. As he coasted back to me I told him to remember to shift so it will be easier to pedal so he rode back and forth shifting up and down. Once he had that part down I introduced him to the chain ring selector. Then we went riding!
He is totally stoked and this weekend we are planning to hit a local "easy" 5 mile loop trail for a test run. I'll post some pics, but my camera is crappy so bear w/ me in tha Dept.
Thanks for the advise guys!
