...........I just resurrected this one. It had apparently come to grief somewhere early
in its life from a rather severe impact to the rear wheel. I usually just toss stuff that
badly tweaked, but I thought I'd attempt to salvage it rather than find new wheelset.

Certainly relacing a Helicomatic rear to a new rim is a non starter.

Anyway, after several hours of cursing and punding and flexing over a sawhorse, which
also involved a Vernier caliper and a very big cross peen hammer and a flat end drift,
the wheel was again relatively usable and tensioned evenly enough that I can at least
ride it around town. Touring on it would be foolhardy, I think.


After a first ride, I can honestly say I am very impressed, and this seems to live up to the
hype and adulation you hear about these bicycles as touring machines.

The gearing is just about perfect for me, and it was a pleasure to work on this bike, given
the various well chosen components. I need to go someplace now.
