Shimano PRO Components Adds Di2-Integrated XC Handlebar, Stem & Seatpost

Just after launching their amazing new XTR Di2 group, Shimano’s PRO components division unveiled a full cockpit group built to hide the wires from shifter all the way back.

Using ports on the handlebar, wires can run inside the bar, through the stem and directly into the frame. From there, the battery will sit in the seatpost or, thanks to a “new headset design”, you can stash the power supply directly inside the fork’s steerer tube.

All junction boxes can then be tucked in the tubes or stem, and a special steerer cap provides access to the front junction for charging. More pics below…

At the moment, we don’t have tech details and specs, so we’ll update as soon as we get more info. In the meantime, the pics give some of it away.

Putting the battery in the steerer would preclude using a star nut or expansion wedge, so we’re intrigued by this bottom cap design. We’ve got a call in to Shimano for details.

 

As one of the comments points out:

Stem is easy to figure out.

1. Tighten top bolt

2. Adjust headset load with ‘bottom cap’

3. Tighten bottom bolt.

A removeable top cap lets you access the battery and/or Junction A for charging.

The seatpost uses their standard clip to retain the battery.

Fork steerer or seat tube, your choice. Unless you have a dropper post.

Automatic shifting using hr or a pm is great in theory, but the automotive industry is still struggling to get an auto gearbox that actually works propperly, without over complicating it, so I think the bicycle industry is still a way off of that.

what are you on about? gearboxes that actually work? xplain please.

the bicycle industry is not trying to make gearboxes btw, so yeah. they still a way off that :P

 

but coming back to the actual point being made which seem to be missing in a huge way: the fundamental hardware for an HR/performance based drivetrain control system is already here. Shimano is showing off what the electronic system can do. Technically, its now down to software and the genius of some mad application developer.

No one said its going to happen tomorrow, so 'still a way off' is rhetorical without adding anything new to the discussion other than general nonpractical negativity

Ok, must I call it a transmission for you then. Hardware asside, my point was only that the software relating to automatic shifting is a lot more complicated than some people think (not saying you or anybody specifically). My only reason for this comparison is because the same basics would be implemented in this auto shifting as is used in a motor vehicle transmission. Shifting is controlled by spaad, power output needed and (basically) fuel consumption and unless you drive a dsg (thats still not perfected) you would have found a lot of frustration with an auto gearbox. But thats just my point of view, comparing it to something I know.

It gets a lot bigger and better than just shifting. Collecting thousands of data points is going to result in new applications we don't even know about and as a result business models.

 

GPS data linked to weather servers to optimize routes etc?

 

Estimated start of this wave of innovation and new uses of all this data we are collecting is about 2017 to 2020 according to most analysts.

 

So this is just the begining

Seamless shift boxes are around. the tech has been incorporated into CVT gearboxes. Volkswagens DGS gearbox uses a few algorithms when in auto mode hence it is able to "learn" your driving pattern to adjust shift speed and when to hold rpm or shift.

Is any auto shift perfect? No because there will always be a situation that will trip it up. But by and large the technology exists.

Interesting! Would be cool to dial in 90rpm and met the bike do all the shifting for you. Use the buttons to raise and drop rpm.

 

Having the gears as electronic signals open up all sorts of doors as the previous posters are saying...

The power of the system is that is expandable and Shimano have a few more aces up their sleeves on this one.

The single shifter preprogram shift map is one trick but theres more to come. AS suggested there are possibilities with;

  1. constant rpm modes
  2. constant power
  3. ability to learn the riders power output against gradient and speed and match gearings and offer different shift maps, like "tempo", or "Break away"
  4. ability to apply an override and back to shift map at the touch of a button.

possibilities are endless.

Shimano power meter? :)

I like the fact that you can run a 2x11 or 3x11 setup and need only 1 shifter!

 

Will be interesting to see what happens at the XCO WC tomorrow.

If you run 1x11 you'll need one shifter but with a front derailleur (2x11 or 3x11) you'll still need two shifters. It says so in the text.

Nope, you can run the 2x or 3x11 system using only the RHS shifter, with the electronics controlling the FD for you.

Damn, really cool. But that stuff be pricey but to be honest I thought it would have cost a lot more. Can't wait to see these in full action.

I stand corrected - sorry!
