Chain Sagging?
 

So I just swapped over to Sram Rival on my Trek and got it completely built and the chain is sagging. I added grease to the pivots and I just dont know if it is because I added the quicklink to the chain or some other problem. If anyone has any input it would be greatly appreciated...
Thanks

Is it a new chain? Did you measure the chain and cut it to the correct length? A pic might help.

Here's an online chain length calculator. Check your chain against this to determine whether or not it's the right length. If it is, don't worry about it. The only reason your chain would "sag" is if it's too long.

Your new bike might have a shorter chainstay length than the old one. Just re-size the chain.
