Seconded. I'd like a little write up. The bike looks "weapon".

I epoxied the two half of the Magura covers together,and flared them at the top to match the width of the nose piece.

Had to notch out a little of the top of the Magura cover for the brake housing to the brake,and had to trim little off the bottom it was going past the Tririg pad holder.

If you expand the 4th pic I drilled/tapped for a screw into the pad holder to secure Magura cover,that plus the fact it is press up and tight to the nose piece.

First off - amazing work!

Secondly - Where's you store the di2 battery? How did you fit the di2 cables through the tiny cable holes under the BB and at the derailleur exists?

The battery,I used the smaller UCI seat post so the battery would not fit.
I dropped the fork out and installed in through the head tube in the upper part of the down tube.

I opened up the the lower opening and RD opening with a drill bit.Once you go Di2 you never go back to mechanical ;-)

Liking your work there.

I was working with a client with a P4 last week. With the right front brake and bars they’re pointy!

Hi, I presume you tried to make the p5-6 fork fit? if so, how did you find the fit around the dropped down tube.

I am running a very similar bike to yours, aduro bar, and front + rear maguras brakes. When I procured the aduro, unfortunately the brake covers were not available. I'm currently trying to make a speed concept under chainset fin fit. I did manage to fit the di2 wire and brake cable through the existing ports inside the aduro cable exit zone. I presume you had issues with a mechanical brake?

would appreciate to hear if you tried the fork, I'm considering purchasing one sight unseen on ebay. Thanks

You have Magura brakes front & rear ?
How did you mount the rear?
The mechanical brake housing through the bars is not a problem
The rear brake is the stock brake and the front is a Tririg Omega

would appreciate to hear if you tried the fork, I'm considering purchasing one sight unseen on ebay. Thanks

I did not try the P5/6 fork.I did a quick visual assessment the fork and the lower half of the P4 head tube and the top of the P5/6 will not fit.

There was a Tri Rig post on my FB feed this morning, talking about them developing an aftermarket fairing for the Omega.

That's why I'll be installing eTap at some point on my P4. No futzing with dremels and drills required :-)

What's the latest on the back brake adapter?

I sent a 3D printed prototype to the guy that designed it and it looked like it worked pretty well. Last I heard he was going to have it CNC'd to actually test it.

Getting a version 2 drawing mocked up. But if notaero already has one built, I'd hope he would be willing to show off his work.

Any way I can get the specs on the adapter? I have a friend who's a machinist.

Yeah, I'll update my other thread when I receive the specs from my buddy.

Unfortunately, I'm the bottleneck here. Since I only am contributing the IDEA of the adapter. Need a smarter person to CAD up the design, a more technical person to 3D print the prototype, and another person to machine the final piece.

Very cool.

Has anyone designed a replacement for the stock bottle? Fairing? Storage?
