I also have had problems with chains, Also I have found that putting a Regina chain on Regina block does NOT allways work, My 1979 Legnano with 1979 Campag Super Record Rear gear. NEW 6 sp Regina Block and NOS Regina chain, even with lots of oil etc, did NOT run smooth at all, I changed to a Sedis USED chain and NOW runs smoth as silk, probly the broken in chain, maybe if I had ridden a few miles the NOS Regina stuff would have worked out OK . THIS PART I LIKE!!! yesterday temp in the 80s clear blue skies, WHITE mountain tops, rode my 1950s Vittoria, Campag Gransport equiped, 40 miles, rode along at 10MPH!!! LOOKING at the beautifull sites, NO shirt!! only shorts!!! 73 yrs old and STILL enjoying life, YOUTH IS WASTED ON THE YOUNG, like the member said AINT LIFE GRAND!! keep on ridiing, thats what its all about, Cheers John Crump OldgoonforeverBrit, Parker, in WONDERFULL Colorado, USA
