Pretty cool but at a hefty price, plus the cranks are ugly.

C's right, the new D-Ace cranks are nasty looking. I'd hafta have SRAM cranks instead. still want.
 
I think the coolest feature is it's ability to adjust the front derailleur automatically so that it doesn't rub the chain when the rear derailleur is shifting....very smart.

Nothing like a perfectly adjusted chain

if they only made women with an automatic trim option. ahem.
 
From seeing what weight queens the racing folks are even on the MTB forums, I can't imagine how much whining there'll be over how many Ti bolts it'll take to offset the battery weight.

oooh, like suntour symetrics did nearly 30 years ago? sorry, the new stuff makes me bitter..... :mrgreen:
 
I was riding with a guy who has this last weekend and the changes are unbeleivable but imho not really worth so much more than a good cable setup... but then i ride fixed anyway lmao... but its right posh... and as has been said it makes the bars feel a little heavier as theyre fair bulky... but if i coulkd afford them... id fit them :D
 
"if they only made women with an automatic trim option. ahem."

LOL

I would check that box on the option list right after "mute button."
 
^^ the first option sort of leads to a muting of sorts, no? lol
