In the past month, I have "upgraded" to Ultegra 10-speed, the following:
- late 70's Colnago Super
- Mid-80's high-end Bianchi of some type (took the original C-Record off of it)
- Late 80's Miyata Team
- Mid-80's Peugeot PSV-10
These were for rides who already have thier plastic go-fast bikes, but have been doing longer (200 miles+) rides and prefer the older frames. These bikes were either hanging in the garage or sitting on wind-trainers. It is odd they all seemed to be coming in at once, and I felt weird about doing the Colnago and the Bianchi, but most of the owners kept the oringal stuff in case they wanted to change them back later (they will have to squish the rear triangles back to 126mm though).
