I used a hacksaw with a 32tpi blade, and a cheap mitre box to help me get a straight cut. I then smoothed it out with a sanding attachment on a Dremel. I have pics (the red Felt IA16) in this and another thread. It came out great.

I was eyeing your Felt today actually. I have etap aero group supposedly on the way and I was considering going with the Alpha One on my Felt IA16. Saw your bike first with a Google search that led me back to the ST. I am sure I will be looking at it some more before I decide. The Shiv pictures with the blip box under the aero bars was also very helpful.

Thanks for posting.

The newer aluminum monopost and not the carbon one, right?

Yes, it's aluminum. Should be pretty easy to cut.

Yep, I actually still use the carbon one. But I have the aluminum, also trimmed in he same fashion.

I second that. Very curious for the scaling.

Any issue with traveling with alpha one and mechanical?

Do you just take the whole stem assembly off the head tube?

I don't have much intention to pack my bike up for flying. Having said that;
If the basebars can stay attached to the bike, the extensions could easily be unattached to make the whole front end more compact.
If the basebars need to be removed, then you might run into more frustrations upon re-installation when trying to route the shift cable housing under the top cap. Tririg's instructions made it look easy, but I found it to be tricky. YMMV.

Yikes.
Not a ringing endorsement.

Thinking taking the aero extensions off means I don't need to touch the shift cables.

That leaves the brake cables. I guess id need to figure out how to figure out how to unclip omega x brakes, or just need to leave enough play to pull the stem off the headset

Depending on the setup, it may be perfectly convenient to remove the bars without touching ANY cables. Feel free to email us with any specific questions, at support@tririg.com - happy to help! Thanks.

Thanks nick.
It will be on a p3 with a pair of omega x brakes +mechanical shifters

So, correct me if I'm wrong, but your intended use case is to leave the base bar on the bike, but remove extensions? In that case, for Alpha One, just remove the Dragonfly (the two vertical-address bolts that connect it to the Monopost) and swing the whole Dragonfly + Extensions + Shifters assembly to one side. They should be able to tuck out of the way with no issue at all. If that's not what you mean, please correct me. In any case, travel with Alpha One is easier than anything else on the market, bar none.

Ok the guys that have alpha one’s, traveling in a bike case is super simple. I flew to Kona using a Premier Tactical case. Base bar stays on. Front monopost bolt loosen. Detach the Di2 wires if you have them. Pull monopost and extensions out wrap separate......it is that simple

I’m going to setup my Cannondale slice with etap and the alpha one. Can you send me some more details on how you mounted your blip box.

Thanks

+2 That bike looks great!!

I have the etap aero group with clics and have ordered the Alpha One with plans of setting up my Felt like this Shiv except for the BTA (using a Speedfil Z4). I thought it is interesting as well that the Omega X brake cable is not using a cable housing. Would like to know how the blip box is connected. Strong double sided tape or something different? I think I prefer this over trying to stuff it into the Calpac.

Also I do not see any other blips? I plan on just using the extension clics.

how did you do that??

“You are experiencing the criminal coverup of a foreign backed fascist hostile takeover of a mafia shakedown of an authoritarian religious slow motion coup. Persuade people to vote for Democracy.”

The Blipbox has a built-in screw mount, which I'm utilizing. You can see it called out here in the manual, basically warning you not to screw further than 5mm deep.



I used a screw from the top down, going through the Dragonfly mount, but NOT using the threads on the Dragonfly. You can see the screw in this pic between the bottle cage screws. I was able to get it to sit flush with the Alden-Carbon mount and not interfere with the cage itself.



This is just an image from the front showing it tucked in nicely between the extensions.



View looking up at the Blipbox from underneath. Since the Blipbox is mounted upside down, the Clics need to cross over to the other side. I am not using any blips so I have the 2 plugs in place.



Any additional questions or pic requests, I'll try and answer as quickly as I can.

Thank you for the detailed info and pictures. This is very helpful.

Just got my P2 back after having the alpha one installed, guy did a really neat job putting the di2 box under the bars (much like the blip box installs). Foolishly when I got home I thought I’d just pop off the topcap & put the junction box in the cavity...

That was a few hours ago & I’ve now resorted to putting it in a bento box.

Reading this thread it seems that I’ll need to file the box down to get it in. But even if I go down that route I’m not convinced I can squeeze everything in, it might be a trick of the photo, but your rear brake cable looks thinner than mine...

Would you mind taking a few pictures under the top cap? I’d really like to see how the brake & di2 cables sit with respect to the junction box (above/below/left/right)

If anyone else has tips/tricks/photo’s please shout.

sure Steve
I will do it tomorrow-having a bit of a time getting my breath after doing the 2nd Norseman race today.

I did the 10 am race too, along with a 3 mile w/u run before the first race, and ran a 1 hr run at my goal RP in between them.
Total of 10 miles R and 90 miles B today (*6 hrs)


Gonna eat now and rest...pics tomorrow, OK?

Unacceptable ;-)

Very much appreciated, no rush.

That's lovely. Any particular reason you went for 3 stem spacers, instead of slamming the stem and putting the Monopost at 5 instead of 2? Looks like your pads are centered, and the 9mm or so of rearward pad movement shouldn't be a deal-breaker for slamming the stem. Of course, that's one advantage to the system - lots of different ways to set it up.

To be honest, I didn't initially think about the various options. I just wanted it to mimic my prior setup and I like having my horns/stem a bit higher. Good to know that I can raise the monopost but I was uncertain about whether or not I was going to be able to get lower due to back issues and I told the shop to use the spacers. Of course, that was silly in retrospect. I do realize that I'm paying a bit of an added aero penalty for the additional spacers...I suspect it won't be too big a deal to remove the spacers, if necessary. Adjusting the cockpit is heavenly! I've really been able to play with my fit and tweak away all soreness. I just love that part of it. Future iterations of this should likely include a slightly larger space for electronic shifting junction boxes to avoid the need for them to be hidden elsewhere.

Ahh... the rear brake cable is over the top of the box..

Did you trim the tabs off the di2? I like the idea of putting it in a little plastic bag & the little bungs around the cap, very neat.
