...I just did a search,
and there are seven pages of results for threads with PX-10 in the title. Which means there are a lot of them still around.
This thread is intended as some kind of central clearing house for information on modifying and/or restoring them. Not unlike the Centurion Ironman sticky thread.
Both of these frames were produced as affordable "real race" bikes, and in large numbers. They make an excellent platform for upgrades and personalization.
In that sense, they are similar. I know there's a lot of good info in the 7 pages of results listing the other threads. I'm hoping to attract some of the more interesting projects into one thread, for inspiration and sharing of opinions on what is and is not a functional upgrade. Also to share some information on what does and does not work well in the process, with some photos of the results and how they are accomplished. I just changed some stuff on one of mine, so I'll start.
