To measure the proper chain length i have to pass the chain from the biggest front chain ring and the biggest rear cassette ring (28), without passing through the derailleur pulleys. So, after the chain front and rear meets, and if i am correct, i have to add two more links.
Ok?
But....the problem is that shimano in the service instructions of rd 7900 says that i have to add , especially for the 11-28t sprocket, two more links. Is it correct? Pls help. Thanks
