I was at the lbs this afternoon and I got talking with one of the mechs about chains and he too knew all about the 'Sheldon' chain calculation, ie., big-big no derailleur, + 1 link. We looked at new Cannondale Gemini 900, and pontificated for a while. We both agreed the Gemini chain looks too long though we did not actually remove the chain and resize it Sheldons way.
He came close to doing so, but the big cohuna (boss man) did not want him/me messing around with a new bike. B*s*a*d!
So we mused some more and I asked him, if I buy a new chain (Sachs PC99) and I shorten it, fit to my Gemini 1000 but make a botch of it, can I use more than one master link on the chain to get the length right afterwards?
In other words, I'd have potentially 2 pieces of chain, 1 master link would have been used anyway, bit would a second be ok, or would I use a more 'permanent' fixing?
