Nice thread. Yep, I'm trying to keep one bike stock. My '90 Concorde Astore, Campy Athena Grouppo. It was my retirement gift to myself and was custom made, right down to the color design. A few years back, I dropped the 42T chainring and added a 39T . This winter, I added a 14-30 cassette. All in the interest of helping me climb, as I turned 70.

My '83 Ciocc , was bought of the shelf in Germany. Came with Shimano 600 grouppo and tubular tires. It has been upgraded through out the years, to keep it moderish. This year, it will get Shimano STI's.

My Huffy, was bought off the shelf, and upgraded to a touring bike. But I kept it to Suntour components. I add and subtract, as needed.

My recently acquired bike, '85 Bridgestone 500, I want to keep in it's stock condition or the like. I did remove the 42T and put on a 34T. New tires, cloth tape and leather saddle. The bike came with 27 in. wheels, but the brakes have enough reach to handle 700C wheel set. Also, I kept the clip pedals, rebuilt and replaced the leather toe straps. I have several clipless pedals, so I can swap-out wheels and pedals as my mode changes for a given ride. The Suntour friction shifting will stay. But I can be L'Eroica (and yes, I still have my leather hair net), or toss on a few modern things.

So my Concorde and Bridgestone, will remain close to the original, while the two other bikes get upgraded, downgraded or side-graded as I see fit. My Ciocc is my pure climbing bike, the Concorde my show off , flat land, Sunday bike. KB
