I need help getting back to the proper chain length. I broke a chain while camping a few months ago, and one of my buddies accidentally threw my chain away so I don't have my old one to measure from. I bought a new SRAM, and just need to know the proper length in order to size it and get back to riding again. I'm riding a Trek 4300 converted to 9 speed, stock crank in the front. I am pretty certain my rear cassette is an SRAM PG-950 11-34. Thanks in advance

Basically you run the chain just around the largest chainring and largest cog, without running it through the derailleur, and add a full link (or a link and a half, depending on where that puts you), remove the rest of the chain after that then install it.
