I'm finishing up the rebuild of my mountain bike. I'm replacing the chain, but I made the mistake of tossing out the old chain before opening the new one. I failed to measure the old chain.
I emailed Cannondale and they told me that my bike was originally configured with a chain that had "107 links and a connector". Do I count the pivots or the plates?
Also, I'm switching from Shimano rear derailleur and chain to SRAM rear D and chain. Does this matter?
Interesting note, that type of chain is called "roller chain". I had to order some for my snowblower once. Doesn't help I know, but I never knew.
Plates, but it will be pretty obvious when you count wrong and its either twice as long, or half as long as required.
When I do new chains I just put it on the largest cog in the back, run it through the rear derailleur full taught, and put it on the largest chainring in the front. Mark the link that needs to be whacked and connect with a master. Done.
This will simulate the most travel that the rear derailleur should ever see. The combo of the lowest rear gear and the highest front gear, even though you should never ride like that.
