My 1990 Giant Boulder I've owned since it was a few months old. I worked in a bike shop and bought this with some parts missing on it. It went to college with me and many other adventures. 5 yrs ago, i pulled it out of storage, went through it, and put some different bars and michelin rock country tires on it. It's been great riding again. I put the tires on my wife's bike when I found a hybrid for myself and just put these on this week. Thumb shifters will always rule!
