Can you convert a bike to Di2?
Can you convert a bike to Di2? With the exception of the DURA-ACE 7970 series Di2 Shimano have actually been pretty good with regards to backwards compatibility. This means that it is relatively simple to upgrade an Ultegra 6770 10 speed bike to 11 speed Di2. The bare minimum you need is two new derailleurs. That's it. How much does it cost to convert bike to Di2? An Ultegra Di2 front derailleur will set you back about $560, while Dura-Ace Di2 is about $780. Ultegra Di2 shifters are $445; Dura-Ace Di2 are nearly double that at $930. What do you...
