Wondered if you could help, I have a Redline 600a series 2, could tell me the seatpost size I need, I just remember as a kid that the size wasn't conventional.. I remember buying a Uni Seat (something like that) Seat and Post and bashing it in with a hammer...Anyway i managed to get it out 20 years later
Hope you can help
Also need a seat clamp
Cheers
Danny
