I bought an 80's vintage Giant Perigee - it works fine except that every now and then the chain gets stuck between the front sprockets when I'm changing gears.
I think the bike originally had 2 sprockets in front - and they went to three as a retrofit - it's a Biopace setup.
I took it in to my LBS - they said they adjusted the derailer and all was well - but it wasn't.
Is this symptomatic of something specif? Is it possible that I might need a wider chain to accomodate the front sprocket retrofit?
I'd like to at least be able to talk a little more intelligently when I rreturn it to the LBS - or fix it myself.
Thanks.
PS - this is not chain suck - the chain actually gets lodged between spockets - and it's a bugger trying to get it back out.
