Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

SRAM Red downshift quicker than both EPS and Di2 something like 1.25 second compare to campag/Di2 1.8-2second.

Downshift what?

"If absolute shift quality is the primary concern, electronic wins out. Di2’s front shifting is still the best available, by a pretty decent margin, and the rear shifting of all four electronic groups is perhaps best described as impeccably predictable. It simply works, every time. No fiddling, no adjusting; just set and forget.

Campagnolo EPS front shifting sits just behind Di2, followed by the new SRAM Red group, Shimano 7900, and Campagnolo Record. With the update to Red, the front shifting quality of the top three mechanical groups is now so tightly packed that it becomes a useless metric, except against the still superior electronic groups.

Rear shifting isn’t so easy to sort. A mechanical system with properly routed and uncontaminated cables and housing can match any of the electronic groups. Red feels like the quickest shifter of the bunch, largely thanks to its short lever throw. But if you time a shift from its actual initiation, or when the cable is taken in or let out, all the top groups end up nearly identical. (And yes, I wasted an afternoon doing this with a video camera.) So, rear shifting is essentially a draw, except that electronic systems will never run into contamination issues."

Peleton magazine have made a comparison experiment with the Campag EPS and Shimano Di2.

Gave it to Scherrit as I reckon he might find it interesting but here's the interesting part.

Aren't these kind of comparisons a bit useless? How well a drivetrain works is decided by one major factor- the skill of the person setting it up? I'd wager a race mechanic could get Veloce working better than you or I could get SRAM red to work.

It looks like they'll be offering both a DA and Ultegra version.

Hmm, I'm going to be one year closer to my pension next month.

I want it now, mummy, now! As suspected the new Di2 will use the Ultegra Di2 wiring and will have TT shifter pods. Too late for me though damn you!

How long before XTR Di2?

Who cares, I want my TT pods. Begone cables!

Does anyone remember the Mavic wireless system? I'm wondering if manufacturers are going to head in that direction over time.

Mavic Zap (or Mektronic)

That looks awesome.

hatches plan to move current groupset onto CX bike

Hopefully I can get this 24hr record then worry about knocking the shorter distances over too.. with a new TT bike and some erectronic shitting.

The best price, that I've found, for a full Ultegra Di2 groupset is £1,049.99 plus an extra £100 for Charger Bottle Cage Mount Battery? Does anyone know of a better deal by any chance?

When I was looking a while back Merlin were the best.

Try Bike24 and see what they come in at.

dimi, an extra £1300 get you this;

ummm, no thanks.

Thanks, but I would need the whole groupset, as my current one is a dura ace 7700 9 speed.

^ THAT is £1,858.57

Yep. The Canyon Ultimate AL with di2 is definitely on my next bike wish list. I saw quite a few in Mallorca over easter and they're really fantastic bikes.

hackaday reader?

Canyon is now on my list of wants too

The aluminum stem on Argos-Shimano's Felt DA time trial bikes features a cutout for the Shimano Dura-Ace Di2 control box.

Shimano Di2-equipped teams ran a wide range of battery mounts. Argos-Shimano places them behind the seatpost but others put them beneath the down tube, underneath the chain stay, or inside the frame.
