Rehabing the Xtracycle donor (Lotus 3000M)

I decided a while ago that I wanted to build an Xtracycle. My plan is to use an old mountain bike that was collecting dust. Having stripped it down to the frame and collected some necessary parts, I just got started on the rebuild. Due to cash flow, the build will be slow, but I will post as I make progress.

One of the issues with the donor bike was the bearings. Both the headset and the bottom bracket had major issues. Trying to be frugal, I opted to keep the threaded fork and just replace the headset. I picked up a Shimano 105 headset from an online seller. Then I learned a bit about headsets. There are two different sizes of bottom race on a 1" fork, 26.4 and 27mm. As it turns out, the one I bought was smaller than my fork. Sooooo, I had the fork turned down to fit the race. Welllll, as it turns out, the the stack height difference between a large sealed bearing and a smaller loose bearing assembly makes a difference as well. Thankfully I live in a town rich with bike shop goodness. Kevin at River City finally set me straight. I have a new Tange headset that spins like a charm and I got to keep the fork (damn that fork).

If I had opted to update to a threadless fork, headset, and stem, I would have only been out a few more bucks and had a much nicer setup. Lesson learned.

That solved, I put it in the stand and filled 'er up with frame saver. (Hindsight: Using frame saver in my basement next to a gas water heater water heater was probably not the best idea...) Let it be known that frame saver is nasty. End of story.

Up next! Bottom bracket problems!

Dude, pass the frame saver on the left hand side.
