Alpha One - Not for just competitors :-)

Just about have everything set for the season(s) ahead. I just need a long ride or two before I trim the mono post. Other than a lot of chain noise (etap needs to be dialed in and chain needs new wax) at the end of a test ride yesterday which included an impromptu race of sorts I was really pleased with the Alpha One bars. Most pleasing was the cleanliness compared to the stock mechanical cables that were an absolute mess and was a constant irritation to my mental issues. :-)

Yep, I could have stuck the blip box in the Calpac and the clics I ordered were the longer cables, but with it below the BTA mount I am content as I don't see it and not competing it's not too big a deal. The Speedfil Z4 / Garmin does sit above my forearms, but it puts the display in a perfect spot for me. Between the Garmin and Blipbox catching a little air it is worth the slight penalty.

The bike felt great. I am a happy customer. Also added another TriRig Omega X to the rear brake.

Quick question for you comparing the Alpha X to Alpha One . . . I have the Alpha X and use the tilt hardware. Is the minimum stack on the Alpha One lower/same/higher than the Alpha X in this configuration? That is, assuming I am not going to use the undermount hardware on the Alpha X (which I don't know if the tilt works with that anyway), just comparing Alpha One to Alpha X w/ tilt and no spacers anywhere.

Yes, Alpha One does go about 25mm lower than the lowest Alpha X overmount. You can see this on the respective fit guides for each bar.

@ryryrocco, I went through all 18 pages of this thread but I don't believe anyone asked you: Did you get a 5 port junction box to fit inside the basebar cavity? How did you do it? I'm considering the same setup (Di2 Shiv + Alpha One) but it seems a few people are having trouble hiding the junction box.

Hi All,

For those that have installed the Alpha, what are you using as a hydration solution. Also, what are you using to hold your Garmin?

I've mine installed and love it. Need to decide now on a hydration setup for long course and where/how to position the Garmin. Cheers.

P.


I have installed the Alpha One on my Shiv. I tried to use an XLAB Torpedo BTA (that i was using previously) mounting the cage in the dragonfly mounts rather then the XLAB versa I had previously used which required me to mount my Garmin using a standard aerobar mount. When the torpedo bottle was mounted in the cage it blocked the Garmin completely. I purchased the "Space Saver Computer Mount" from XLAB, but i felt it was sitting way to high on top of the torpedo and would be to much of an aero penalty.

I switched to a Profile Design "Aero HC" bottle and mount I had lying in the spare parts bin. It fits well, but the Garmin is a little farther back then I would like. Its not right under my eyes, but almost between the pads. I do like that the profile design is a little easier to clean then the torpedo. I have had only one ride so far, but it seemed to work well.

I may try to find the "Aero Computer Mount" that came with the torpedo https://www.xlab-usa.com/...-computer-mount.html and see if I can move the Garmin forward between wrists more, without being blocked by the bottle, but question if it will work.

Here are some shots of my setup before I changed to the Aero HC bottle.

Still have to secure the di2 wires to the monopost, to tidy up the front (done after pic) and trim the monopost (after receiving the new one and some more riding to make sure setup is dialed in)

Opinion question:

How long or how many rides would you put in before feeling confident enough to trim the excess mono post?

I was thinking a couple months with at least a couple 100 mile routes. I set up as close as I could to the original fit and did a short test ride (30 miles). Just a bit skittish on cutting off the excess post. I have no events and at the moment I am just trying to get in base endurance.

How skittish are you about paying $84.99 (currently $76.49 with 10% discount) for a replacement monopost? Because that's your worst case if you cut the post and regret the decision.

That is one of the nice attributes of being able to get another if I screw it up. Hope I don’t need to.

My opinion - don't trim it. I get that aesthetically, it's nicer without the post. But from an aero perspective, the weighted-average drag of the post is only about 4g. We will have lots more information about this and related topics soon, once we officially launch the universal cover.

Moreover, if your bike is compatible with the universal cover, then just put the cover on and then you definitely wouldn't need to trim. And you'd get the added aero benefit of the cover itself. Again, lots of good data coming, soon.

Thank you very much for this information. At 55 I am actually fitted more aggressively than my previous bike. If don’t trim it and I don't age well I can raise it. Great to know there’s not much aero penalty.
