In answer to Nath's question, I'll name both bikes. The older one I bought in 1978 and is a Centurion Super LeMans. That's the one not worth talking too much about, and the other is one I bought through Trek's employee incentive program for bike shop workers back in 1981. That one is a Trek 710, which I recently had repainted by Ed Litton in Point Richmond right near where I live. The Trek originally came with Campy gran sport hubs and SR bars, stem and cranks. I changed those right away to Camp gran sport cranks pedals and Cinelli bars and stem. After the repaint (with some new braze-ons added) I built some wheels up using some Campy High Flange Record hubs I found at garage sales. I had to rebuild the rear hub with new cups as well as cones and bearings, but the front hub might not ever have been used. Well, maybe I'll talk a little about that old Centurion. I've used it as a commute bike for a while as well as that other Bianchi I mentioned. The thing about that Centurion is that it has cromed chain and seat stays, and chromed fork blades, and it has 'Hi-Ten' butted tubing. Sure that is nothing special, but I bet lots of people on this list hang on to things like this that only they like. While most of the original parts to that bike are gone, I do have some parts from the same era that would be upgrades, like Sun Tour Cyclone deraileurs.
For others that may second Nath's suggestion that I change from Digest, I already have. Choosing that was a mistake when I first signed up and I had planned to change that anyway, but the point was a good one to pass on to me.
