I thought they were going to use the Ultegra Di2 shifters, just with no buttons on the left hand lever?

And might be the better choice as I see it has a higher efficiency rating.
I'd want to pair it with a Dynamo hub up front, dual discs, mudguards and 28c tyres.
Boom! Come at me weather.
Think it's worth getting your Oaks to have EBB/sliding drop out for future use?

The range of the 11 speed hubs are perfect, the ratios felt almost like a normal cassette with the exception of the first and last, the 8 speeds is regarded to be the most reliable but got a real odd ratios which take some time to get used to.

Would love to know this, also want to know whether there's a left hand version so I can purchase both left and right levers without button separately, the hoods are real comfortable.

In my minds eye I've got the following drivetrain:
Alfine Di2 11 rear hub
Shutter Precision clutched dynamo front hub
Rotor cranks, P2M meter, belt driveAnd then Hayes mechanical disc brakes with the Di2 levers.

I never understood what the big woop was about belt drive. Sure is quiet and "low maintenance" but a good chain is also quiet and low maintenance too.
There are too many downsides: expensive, need for a special frame, special chainring, special cogs, tension is a bitch to setup properly.

what's the point of an electronic alfine? the regular one doesn't need any maintenance and the cable is covered
full length. -

8bits: Clean it with a hose and put it away...
It's the zero maintenance thing that appeals to me.
Go for a proper ride in the country side in inclement weather and you have to run your chain through a chainbath, then re-lube it, or you increase the wear rate by about a bazillion percent.
WIth a belt drive you just lean it against the wall and you're done.

Also if you get a puncture apparently (I've not done so) putting it all back together properly is a bitch.
Di2 you plug it in and it works.
Plus, and the main reason I like the idea, it sounds cool.

Proper winter bike should have an oil bath chain case to avoid such issues.

I have one on my foldable and this is true, not a huge pain but is annoying.
For me the main reason is going to be the aftermarket shifters. For the mechanical we were stuck with shimano (trigger or twist) or versa (sti) or jtek (bar end but since the inventor died the son kinda abandoned the business). With di2 you put your buttons wherever you want how you want, you can build a cool townie without the modern aesthetics of a trigger...or a riser with a minimal look...

And then Hayes mechanical disc brakes with the Di2 levers.
I've tried the new Hayes CX-5 (if that's what you're referring to) from a Norco CX bicycles at work, was impressed with the modulation which felt IMHO better than the Avid.
The pads haven't worn in yet due to it's being new but comparing it to my CX with Avid and decent levers, it's a noticable difference (levers were Tiagra with the Haye).

what's the point of an electronic alfine? the regular one doesn't need any maintenance and the cable is covered
full length.Currently with internal hubs, you need to resist pedalling in order to shift gear, the opposite of what you'd do to a bicycle with a derailleur.
This can be annoying when you don't want to stop pedalling while ascending for example, of course practise make perfect but still nagging.
The electronic alfine will shift it properly without requiring you to resist pedalling, the other factor is that there's only one drop bar shifter for the Alfine, and it's shit, even the old Sora shifter perform better than the Versa one, you can't brake properly on the Versa due to it's being so incredibly spongy with disc.
I welcome it. I would like a drop bar road bike with Alfine Di2, having said that I'm still quite happy with my cheap mix of Sora/XT/Deore groupset on my CX that still perform flawlessly, I just need to replaced the chain every 1,500-2,000 miles.

I haven't done anything to mine in almost 2 years. When you get a puncture you just
unplug the cable.
but I just saw its pretty cheap. what trigger options are there? -

hm, maybe alfine Di2 with some external buttons and RED hydraulic levers.

The ABS idea is really interesting tho.
There've been a few "ABS" systems for bicycles but none have come into mass production.This one is quite interesting - although all the ones I have seen work on the same principle.
http://www.treehugger.com/bikes/slidepad-regenerative-abs-braking-for-bicycles.htmlI read about the concept in the very old 'Bicycling Science' book; all these modern versions seem to have used it as their inspiration. According to the book the original system was tested so many times that the fork crown snapped, and not once did someone go over the handlebars.
Although it does mean you can't balance braking between front and rear on slippery surfaces or do awesome skids. Plus if your single lever/cable breaks you don't have an alternative.

I reckon the Alfine stuff will be Canbus, same as the Ultegra Di2, which means that it's not as simple as it used to be- with my first generation Di2 you can, no lie, use a doorbell to change gear- it's a simple interupt style switch whereas the newer stuff needs a chip to modulate the signal in such a way that the system recognises the signal.

This^
Plus most mud from the trail is piss easy to remove, when it hasnt been mixed with chain oil and sprayed all over the rear end. If things are preety shitty. Just soap it down. If the hubs and BB are well sealed. Theres no need to relube anything.

all this on steel frame? did you think this through?
You don't like your Boardman so instead you are going to build a really expensive,
heavy bike with an soft, indirect feeling drivetrain?
You worry about the drag of the dynamo hub but you get an Alifine?
You get a beltdrive and electronic shifiting because you think that will not require maintenance
but then you go with mechanical discs?Since you are a Princess and the Pea type cyclist I predict you will not even get through
the run in time of the Alfine before you hate it. -

I think he didn't like his Boardman because of the way it ride rather than the extra weight.
mechnical discs make sense in the long run.

I quite like the idea of being a Princess and the Pea type cyclist- does this mean that I have 20 layers of carbon fibre in my saddle, but still feel the bumps?

Doubtful if you have a steel frame, even cheap alu seatpost are still comfortable.

Sohi is your Alfine the 8 speed or the 11 speed?
I've no direct experience of eiither, but this review seems very positive: http://road.cc/content/review/27971-shimano-alfine-11-hub-and-shifter
-

8, but I think the soft clutch is in both. That has the most effect on the feel. the drag goes away after a while.
it seams to kill torque more than constant power.
I'm curious to know how much the shifters will cost tho, they were pretty inexpensive on the mechanical version, I'm guessing it will hike the prices way up :-/
