chain length on cassette change
Madone 5.2 2011......have a sram 11-26 cassette on bike now w/ a ultegra 6701 chain...I have a new 11-28 Ultegra 6700 cassette,and dura ace 7901 chain that I want to install,does the new chain need to be longer with the 11-28 cassette? I can always try out the 6701chain w/ the new cassette....any help appreciated. I am a good Shimano mechanic and tuner.......too bad it's fishing reels
