I've got a slight issue with my old 1980s Bianchi. Its a bit hilly round here to say the least and when I get out of the saddle the darned thing jumps down a gear making life a good deal harder than it needs to be.
Suspecting its a worn chain I had a quick measure using the 12 links theory and its between 1/8 and 1/16" long so it needs changing I reckon.
The old bike runs an Ofmega front chainset and Simplex SX610 rear deraillier, I can't see any markings stating what the (6sp)freewheel is or what the hubs are.
I was thinking I'd just swan into a bike shop and buy a new freewheel and chain but oh no, its not that simple as its 'old' and everything now is 10sp and more.
So...Help! Where do I get a new chain and freewheel? I don't have an issue with changing the number of gears but would like something a tickle lower than the 24tooth biggest at the moment, its friction shift so indexing isn't a problem.
