DI2 or Dura Ace on new bike?
What is the bike for? I have ridden Di2 and it is very nice. But I’d go for DA9900 as I think this is the outstanding performance groupset. Teams were switching to manual DA, although the new Di2 uses the same electronics as Ultegra so may be more reliable. Autotrimming is really not so much better than ordinary trimming.
One aside, a racer friend complains of cold hands when using Di2 because there is no neeed to move them about.Posted 4 years agojock-muttleyMember
Dura Ace the electronics in Di2 are simply not reliable in the wet, look at wiggins in the Giro and that yank rider on his first descent of the Alpe d’Huez stage last year THAT was electronic gearshift probs through & through … water & electrics don’t make for happy bedfellowsPosted 4 years agochief9000Member
For me the DA hands down. Its a brilliant groupset, smooth and completely reliable. A pleasure to have.
The Ultegra Di2 is tempting you as its the latest technology (lets say) but its a lower groupset.
My humble opinion and preference is that today I have to plug almost everything in and charge it. I have several drawers full of cables and chargers. I don’t really want to add my bike to this list of things I have to charge (yes i know the charge lasts a while, nevertheless i don’t want to do that).
For me the bike stands for freedom, heath and well being. I dont want to have to think about charging before I go out. Also, adding a battery makes a bike less sustainable and is a little contradiction in my opinion.
A cable is reliable and already does an excellent job. Why do we have to make it more complicated, expensive and worse for the environment?Posted 4 years ago
