TriRig Alpha One

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?

Brisbane, here. My Alpha X came straight through, no worries. I have had wheels held up in the past, but nothing from TriRig.

Hey Thread,

Do we have consensus on the cleanest way to mount a Garmin on the A1?

There are lots of good ones. But I tend to recommend parts by Glen Alden: www.alden-carbon.com. His BTA mounts let you put the computer wherever you want, with a minimum of fuss. Or for a very elegant solution (but one that doesn’t give you as much say where the computer goes), try his “Extended Computer Mount”: https://www.alden-carbon.com/extended-computer-mounts

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.

  1. Thanks.
  2. Ditto. I’m not finding anything examples on the site or via google image search.

Working on photography for that this week. Once ready, it will show up on the “Installation” page of Alpha One. Stay tuned!

Oh man, it was a bit of a challenge to run mechanical housing through the top cap/cover. It had me seriously considering if I should just pay up for Di2.

I hope the pictures are helpful and here’s the process that worked for me.

  1. Here’s a shot with the Brake lines in place and the top cover off. That part went easy enough.

  2. Trying to put the cover on with both mechanical gear cables/housing

  • It’s really hard to get the cable housing to stay inside the center notch…
  • It’s impossible to install the top cover and squeeze in both gear housing lines at the same time with the monopost in place.

My solution.
a. Take out the monopost
b. Run one gear housing first
c. Run the cable line from the other gear separately.

  1. Feed the other gear housing through

  2. Insert the monopost back in.

  3. That’s basically it. Here’s a couple more images of the cables out the front and back. Notice that the gear cables are not routed through the bars (as Tririg suggested) I’ll likely post a couple more pictures in better light/quality tomorrow to show the finished product. It seems like there’s a lot of adjustablity in the monopost height with this set up.

Here’s a follow up to the installation with better pictures. As you can see, I can easily adjust the height an make full use of the monopost range. I clearly have to trim the monopost, but I’ll wait until after I do a Retul fit.

I’m installing the alpha one on a Cervelo P2 frame. For those familiar with cable routing on these frames, you can see that I decided NOT to reinstall the cable port cap behind the stem. This is intentional as it would severely restrict movement of the cables and limit steering. I suppose the cover would be good to keep out rain, but it’s not really relevant otherwise.

My extensions are set up within the UCI exemption limit as I mainly participate in TT’s these days.

Doesn’t look like running the cables through the extensions would have hampered cable routing or cable drag, any reason why you didn’t? Is it to facilitate Pad Y changes without having to re-cable every time? Will you be running the housing through the extensions once you decide on a pad height?

Yep. I want to keep some stack adjustability for the time being.

I have tweaked my fit quite a bit over the last 10 years, on my own, and I’m at the point now that I’d like to see what a well respected fitter thinks/recommends. I also want to back that up with doing some Chung aero testing. So, I want to keep some adjustability for now.

I suppose I can route the housing through the bars when I’m all settled in, just for the sake of aesthetics.

That’s the most important consideration! :wink:

ETA: forgot to say sweet looking setup!

Thanks for the pics!

Who makes that Garmin mount?

Wow, thank you. Unfortunately you may have just sold me on di2 lol…

i hear you! …I’m still considering Di2 myself!

That’s a K edge Slpayd garmin mount. My integrated road handlebars use this mount type, and I had an extra lying around. You can also get carbon versions (not k-edge brand) from eBay or Aliexpress for cheaper (~$20)

Great pictures of your setup! You beat us to the punch :slight_smile:

Regarding the Splayd mount, note that you should also be able to attach it on the underside of the Dragonfly, leaving the top surface of the Dragonfly available for bottle cages and the like.

I’m sure you’d take better pictures. At least your workspace wouldn’t be as ugly.

Thanks for the tip on the Splayd mount. I just installed it on the underside and it looks better (and maintains more functionality of the dragonfly mount.

Pictures are up, at the Alpha One Installation Page.

Surely, I’m not reading this correctly. Is the "dragonfly’ with narrow arm cup mounts really an extra $759.99?

I think the description in that screenshot explains why.
