A question about the seat post.
There are new regulations from the DTU and the “sword” as it is now on the seatpost and as it is also on Canyon will probably be prohibited.
Is there another way to attach water bottles to the seat post? Is there perhaps a cavity like on the Avenger frame here?

If, and it is a big if, that DTU sanctioned races don’t let you use the saddle mounted bottle cage, just get a saddle mounted system instead.

Yeah they look good and I like that you can have your blips mounted on them. How much did you pay for them? There are not too many vendors selling them in Europe...
The cheaper option would be to go full mechanical disc brakes. Not too sure about this right now. Mabye I should just get the RideRever levers

I got mine for £170.99 on eBay (with a discount code) from a bike shop who also sell on there. You can actually pick them up there now for even less than that! (https://www.ebay.co.uk/itm/335035938661?var=544262923126)

Haven't travelled internationally with the TT bike yet but will be in May. Plan is to put disc brake pad spacers in for the flight, maybe even turn the levers 90deg inwards.

I am thinking of the same in the future
I would try these- https://www.riderever.com/product/5/17/28
paired with Sram rival axs and blips.
still on fence about frame as i try and do UCI nationals and gran fondo TTs - unless i can get one that is very close to original and slap a UCI sticker on it!

I’m running these RideRever hydraulics on my Velobuild VB-TT. They’re good, haven’t used the SRAM Hydro’s to compare to. But once upon a time these RiderRevers came stock on Cervelo TT bikes.

(okay, one thing: I'd like the BTA to be horizontal to the toptube and not with the angle of the wedge --> given that you like DIY, I think that's an easy one for you )

I agree it would look a heck of a lot more satisfying if it was parallel to top tube, however I like an angle to it so when I’ve got race nutrition in the BTA bottle it won’t leak out the bottle as easy.

You should see some of the other shit house things I’ve done after seeing the arms race the pro triathlon peloton has done with bottles. Pic below is the more tame set ups I did.

That looks great!

Are those the Winow extensions? What do you think of them?

Yeah these are the first release of the Winow extensions paired with a drag 2 zero 15 deg spacer. Generally pretty happy with the extensions. Still yet to sort a garmin mount as I don’t fancy paying the £25 for the winow ones / I like DIYing it.

All parts have finally arrived and got the rig set up. This is what it looks like pretty much in race set up (1st race is IM Lanza so front mech needed, but will be removed for flatter races).

Made a DIY BTA bottle cage plate from an AliEx carbon plate and a 3 slot bottle age adaptor common in MTBing.

The Trek Speedconcept Gen 3 (disc brake) specific downtube bottle doesnt work on this frame as it comes, however I'll find a way to mod the that bottle cage to fit. That or use the Orbea Ordu OMX or Cervelo downtube bottle.

Best pic I have of it at the moment. Will post pic of bike with it on when I get round to taking it. GP5000 S TR installed very easy on both Tri Spoke and Disc wheel.

if you already say that it feels short I might need to look for a different frame...

I think I just like a really stretched out position, came from an XL Speed Concept really stretched out.

I will be getting some reach extenders like these (https://fasttt.bike/product/forward-reach-extender-bracket/) to really dial in my position. Still much cheaper than getting a branded frame with longer reach. I also just like tinkering really
