|Is there an easy way to determine the proper length of a new chain? I think I saw something posted here, but I did a search and didn't find anything. thanks|

|Yeah, count it to 112 links. That's what you are gonna use. I am willing to bet money on it. Like 98+% of all bikes with a derailleur use exactly 112 links of the 116 link chain the manufacturer sends you. <--- OK, don't really take this seriously!
But, for a road bike there are a few accepted ways to measure. 1 is put the chain on the big ring and wrap around the largest cog not going thru the derailleur and go till the chain touches itself... then add on two links to that.
The 2nd way is to put your chain on thru the derailleurs on the large ring, small cog combo and pull your chain till the ends touch with your rear derailleur at a 90 degree angle from the body to the cage.
Here's some links....

|Maybe that's it... Actually I think I meant to type 108 anyways.... I was joking when I siad that though... I was at the shop one day and a customer wanted to know how many links were on a chain. I told him it varied, but he really wanted to know, so I suggested he count them. He got mad so at that point I just made some crap up and told him that all chains are always 108 links on adult road bikes....
He told me I was full of crap, so I told him again to count. I was right on the bike he checked and it was funny.

|I just make the chain the same length as the one I took off. Of course if this is a new build then you have to use the method suggested by others.
