So just got my TW up and running after roughly 2 months of wasting time with "professionals," then finally handling the situation myself - as I should have just done in the first place...Anyway! I went for a ride today around the local jeep trail and had a blast riding again for what felt like the first time in ages. The bike is running the best it has since I've owned it. Then I got to my usual turn-around and heard my rear tire make contact with something that sounded like it may have pinched it. So instead of turning around and heading home I stop and take a look. Well, sure enough, right away I spot a nail in the tire. This is where I made a big mistake...I thought to myself, "I have Ride-On in the tubes - so pull the nail and watch it work!" Lesson learned!!! Ride-On didn't do jack. The rear tire went totally flat in about 1/8th mile. Maybe the puncture was too far over? So, I ended my "ride" by walking the bike about 3.5 miles back to the house. It was no fun at all! A new tube is inbound, and it's time to assemble a field repair kit.
