You can do it. And have a clean set up. Some of the alpha one bars based on what other people have posted can fit DI2 boxes with/without some modification. I posted my bar with the alpha one and you can barely see the di2 wires but I taped them down under the stem cap and ran them into my bento box into the di2 box. If you blow up the photos you can see where I did this on my P2. I’m sure there are some other creative things you can do but that’s what I did.
- Ability to hide Di2 junction box. I couldn’t fit my junction box in my particular bar. I ran the wires into my Torhans bento box and kept the junction box there with A1 bar. With the AlphaX a Di2 junction box fits easily within the bar. All you need to do is remove 3 screws and you have easy access to the box. I really like the esthetic of having a really clean no exposed extra wires setup I get with AX. First world problems.
I’m looking to clean up the front end on my Cervelo NP3 with Di2 this winter, and this has me concerned. Does anyone have pictures of how the Di2 is placed with the Alpha One?
See the FAQ at TriRig.com/AlphaOne - we show pictures of a Di2 installation towards the bottom of the FAQ.
Awesome, somehow I missed the FAQ under the “Tech” section. Looks good. Thanks also @OzTx3!
Just bought one for my better half as chanukah present. Any reccomendations on how to get a xlab torpedo to work with the dragonfly?
the xlab cage will literally just bolt on

You just bolt the cage right on. It has M5 threads specifically for that kind of application.
Nick,
I have just got some Alpha one bar and they are slammed. Is it more aero to cut off the extra monopost that sits below the bar, or is there an advantage to the double wind foil of the monopost and headtube? FYI, it is one a P5.
I doubt you’ll see much of anything there, but I’ll be aero testing that very thing in a few weeks and will report back.
A P5 + Alpha One = fast bike.
Thanks Jim, I will be awaiting your report. The only issue I see is for us low and long riders and if we can I get to into our normal fast position on this setup. Also, if you plan to come back to the Springs let us know.

The Monopost is very efficient, and I doubt you’d be able to measure any difference from cutting the portion ahead of your head tube. Moreover, it’s always nice to be able maintain the ability to make quick position changes.
So I’d keep it.
Just pulled the trigger on this for my P3. Already have omega X so looking for a good improvement in position and some aero.
Jim do you have results for the P3 with P5 fork? would there be any substantial gains? or just aero-coolness?
Thanks!
Here’s a shot of the Alpha One mounted up to my wifes PRfive.
Hi everyone.
How do you manage to hide junction box in the Alpha One ?
Hard to put 5 ports junction and wires… Any tips ?
Thanks

In theory you can, see: https://www.tririg.com/store.php?c=alphaone&page=faq but I think individual results may vary. On my wife’s QR (pink bike above) the 5 port is hidden in a cavity in the front section of the bento box, so all wires run to it and the wires just pass through the Alpha One. I am also swapping my Shiv from an Alpha X to an Alpha One and so far no luck with the 5 port fitting. I have an Omega brake and terminate the brake cable housing in the Alpha One cavity and run bare cable down to the brake which means the cable housing is 90 degrees vertical and that cable housing pretty much makes it impossible to fit the junction :-/. I had no issues with the Alpha X but the cavity was longer so the junction fit in front of the brake cable housing. I need to play around a but I might need to swap to the new bar end junction A and just put a 4 port B junction in the Alpha cavity. I’ll keep you updated as I make progress.
One big help can be to cut off or file off the mounting tab on the back of the junction. Perfectly safe to do, and it gives you several extra mm of room.

Already done but Still very complicated😬
I haven’t seen a ton of mechanical setups but those that I have generally have cabling run from extension end to top tube port via a gentle bend (out in the wind). Is that the preferred? I don’t think Shimano or Jagwire is flexible enough to try and pull close to the back of the monopost and through the cap…maybe Alligator I-link? Even though…shifting would have to take a hit…right?

How I prefer to do it (and how we set up Omni builds with SRAM 1x mechanical) - keep the shift housing OUTSIDE the extension. Hide it under bar tape, then after it exits the bar tape, it has a nice gentle path down, around the Monopost, and into the cable inlet at the front of the Cable Cover part. Virtually no extra frontal area exposed to the wind, excellent functionality, and this option makes it really easy to make adjustments to stack and tilt without binding the cable. Personally I think it looks better than your other suggested option (out the back of the extension), but if you’re planning to make EXTREME changes to stack and tilt over time, this option potentially makes it a little easier to do so.

Any pictures? I’ll be installing my Alpha One with mechanical shifting over the holidays.
Any Aussies out there with an Alpha One or X able to let me know if your bars got held up at customs. Tracking says they left San Francisco on the 2nd of December but nothing since. Did customs chase you for GST?
