Note: the older SM-EWW01 is also called “D-Fly”. The mountain bike displays also feature the same connectivity. Current generation units are the EW-WU111 (mounted near front of the bike) and the EW-WU101 (mounted near the rear derailleur).
#10 vs 11 speed upgrade#
If you would still like to upgrade your 7970 bike however, have a look at the Building a Bike guide that lists the components you need to build a modern Di2 bike. The older 4-wire system isn’t compatible with any current (2-wire) E-Tube component - you simply cannot connect them to each other. This is most obvious when looking at the plug.
#10 vs 11 speed series#
The 7970 series was Shimano’s first Di2 road bike series and when they released Ultegra 6770 in 2011 they made some changes that render the DURA-ACE 7970 hardware incompatible with any newer Di2 hardware. You could of course replace every component on your bike, but that would be costly - and not what this page is about. Unfortunately, the DURA-ACE 7970 series as released in 2009 cannot be combined with modern components. Whatever your reasons, this page should answer any upgrade-related questions. I could go on because the list is virtually endless. Tidy up wire routing and improve your bike’s aesthetics.Enable Synchro-Shift by upgrading derailleurs/battery.

Replace broken parts and upgrade at the same time.Upgrade from Ultegra 6770 10-speed Di2 to 11-speed Di2.People have contacted me for advice on upgrading their bikes for the following reasons: The front is still just 2 positions (small and big ring ), but for more precise shifts, I would think the cage would be made specifically for an 11 speed chain.There are plenty of reasons for wanting to upgrade your old Di2 bike to a more modern setup. You may also need a new front derailleur to accomodate the different chain, but I'm not sure on that. So in general, in order to convert your bike from 10 speed to 11 speed, you generally will need a new rear derailleur, rear shifter, chain, cassette, chainrings, and possibly a new rear hub. I've seen people claim there is a way to convert a cassette body to accomodate 11 speed, but haven't done enough research on it myself. Some rear hub cassette bodies are only designed to accomodate up to a 10 speed cassette. I believe it's possible to get 11 speed shifters to work with 10 speed derailleur.ġ0 speed chains are slightly different from 11 speed.ġ0 speed chainrings are slightly different from 11 speed, but in most cases, you can simply swap out the chainrings instead of buying a whole new crankset. Whether or not you need it is highly dependent on if you wish you had another gear when riding.ġ0 speed rear shifters are not compatible with 11 speed rear derailleurs.
