| Trek 720 - Bicycle Before |
This is an interesting week around the shop. Bob from Georgia brought two Treks for restoration on Sunday afternoon while he is visiting family for the Holiday. Which means I must have them complete by Friday. I hope to be done before the holiday. It helped that I ordered the parts before the bicycles arrived.
I am starting with the larger blue Trek 720. The bicycle is well used which I love to see!! Tires are already new, it is very dirty, has some rust and can use a good tuning. The rear gears slip some so the cassette and chain are going to be replaced along with the brake pads, cables and cable housings.
I disassembled the Trek and had a bit of a hard time removing the bottom bracket with integrated front derailleur. I had to clamp the a large wrench to the bottom bracket removal tool to get leverage. The frame is free of major chips and scratches, there is a few dings to the decals, mainly the frame is dirty and very dull.

I do not know what happened to the photos of the frame polished, but it turned out beautiful. I guess it will just have to be seen through photos of other parts.
I cleaned the headset and then polished it. the headset was heavily rusted and slightly pitted. I polished the components, its not perfectly polished but much much better then it was. I then installed the bearing cups, greased the bearings and installed the fork. The headset turns very smooth, a lot better then it did before.

Next was the bottom bracket and front derailleur. The front derailleur is integrated into the bottom bracket. This makes aligning the front derailleur very easy. The front derailleur was very dirty and had some rust. I cleaned it and polished it and now all looks and functions great.

Next came the brake calipers. The brake calipers functioned slightly rough and the caliper arms where corroded. I disassembled the components and polished the arms. the calipers look fantastic and function wonderful.

Th stem and handlebars where badly rusted. It took a lot of polishing but eventually turned out very nice. There is a little pitting in a few spots but a little maintenance will keep them looking good.

The rear wheel was very dirty, the grease and bearings where shot. I cleaned and polished the hub and hub components and installed new grease and bearings. The rim cleaned up nice. I trued the wheel and installed the new cassette. The wheel is a night and day difference.

The rear derailleur was probably the component that was in the best condition. It only need a cleaning, slight polishing and lubricating. The rear derailleur functions very smooth.

The front wheel was in the same condition as the rear wheel with more corrosion on the rim. I completely overhauled the wheel. Cleaning, polishing, new grease, new bearings and truing. The wheel functions very nice.
