FS: Shimano pro Di2 finishing kit /cockpit. Pro di2 alloy handlebars and Pro tharsis stem.

i have for sale these 2 di2 related bits of kit.

• shimano pro tharsis stem with battery case. 100mm and 6 degrees.
  Allows you to store the di2 battery in the steerer, and the 4 port junction box in the stem.
  sort of made for mtb but can work for road.
  40£

• shimano pro alloy di2 bars, stiff and light bars, and allow an internal bar-end junction set-up.
  33£

You could use the 2 together for an all internal setup but the stem also allows the bar cable to enter and exit below the clamp.

The bundle would allow you to set-up di2 routing with only 1 cable going to rear derailleur. very neat for mtb or that gravel thing everyone is talking about.

The stem has its own headset compression system, meaning no steerer bung expander.

Could be interested in the stem... You say "Allows you to store the di2 battery in the steerer, and the 4 port junction box in the stem". Any pics of the the battery box, and more info as to how junction box would fit in steerer?

Also interested in the stem, and same question as above
Cheers,
Matt

i will sort out a picture

Interested too as I am moving onto a Di2 setup!

Bars are stamped 42cm - is that C-C?

Looks like the junction box goes into the stem and the battery attaches to the fork bung - NEAT!

exactly what tu as dit @Vince.

i think you can have up to 3 cables exiting the stem below the clamp, making it possible to supply both derailleurs, even without such bars with a stem hole.

needless to say that i woud favor a bundle sale, and could discuss the availability of a bar-end junction.

So with a road bike setup with drop bars I’d still have cables coming from the front of the stem to wherever on the frame the cables become internally routed?

yes... one cable for 1x11 or if you still had a split junction in the downtube, 2 cables if you wanted to route both derailleurs from stem.

those new modern all integrated aeroish bikes use heavy oversized proprietary spacers to hide what they want to hide. personnally i know which system i prefer.

if you would use this on a rim brake bike chances are you would have 2 cables still, along on of which the di2 cable is usually strapped.

bars are 42 ctc, i forgot

Not really related to this sale, but it's worth noting for those who might be considering the Pro Vibe Di2 aluminium bar set-up, that you can't actually run a "true", internal wiring set-up with the bar end junction boxes.

Those ovalized holes at the end of the bar drops are where you route the e-wire from the internal bar end outside of the actual bar, and then run the e-wire along the bar profile outside of the bar and under the bar tape.

I've been running this set-up for a while now, and was a bit miffed initially that this is actually the routing set-up. Now it's done, I barely notice the wire under the tape tbh. Only reason I can see why Pro decided against adding routing holes near the bar bend close to the lever ports is to conserve stiffness in what is (I guess), a high stress area.

The carbon version of the Vibe bar does have full routing capability though...

thanks for killing my vibe.
yes the carbon version of these bars allows to run the cables straight into the hood area. they are also 4x times the price

Doesn't affect your set up though with the stem housed junction box.

And the bars are very, very lovely I might add- despite the slight bar-end idiosyncrasy. Even if you aren't running Di2, I'd recommend the Vibe bar and at £40 I'd have yer hand off If I needed some more...

Aaaaaand...... even if you DO want the bar end knobber, the external/ under tape thing really isn't a big deal- just though it was worth pointing out to folk.

B to the UMP

cheers,
what he said !

Thanks for the extra info.

The overall package stem/bar/junction box is not for me right now.

Will hlook into PRO Di2 carbon bars.

price drop on the bars

price drop on the bars, I actually have 2 of those bars !

Do you still have the bars? Also you mentioned the potential for a Di2 bar end port to be included as well... Cheers

I still have one pair of bars, yes (had two). The bar end junction caused a riot ...long gone.

Cool, Ill drop you a pm regarding the bars

you're welcome
