GRT is 2x as well.

The 1x is stated as that chainring is biger and sits more towards the frame. And bigger sizes (of 1by) currently do not fit).

I have my eyes on it as well. And also want to set it with 2x Di2. But nobody can say the tyre clearance in the rear with Di2 FD. Probably less than 57mm, but not necessary. My Addict Gravel is more limited by chainstays, than with FD cage.

Also, hopoefully someone can also confirms, that frame has a hole for Di2 wire for FD. Funny, Evolve Cima GR is also 2x, but reports say, it has no FD wire hole, so it is only Sram possible.

That also makes me wonder, if GRT Shimano battery goes in the seatpost, or somewhere else.

@Requiem84, maybe you can explain a bit further?

Yes, the Di2 battery goes in the seat post.

Current version GRT can take 48/31T GRX 2x chainrings without any issues. We didn't try any other sizes though.

To those with who have R280 hubs, do you know if there is any 3rd party compatible freehubs? I need to change from HG to XDR.

They are compatible with original DT Swiss star rachets version freehubs.

Particle GCX52 Hyperlight (52mm deep, 25int/32ext) - 1022g

XMCS T1100 w/ new Lightweight Hub (50mm deep, 26int/34ext) - 1052g

Both are UCI approved. And both are freakin amazing out on the real roads.

Actually UD paintless finish UL layup  about 1020g without rim tape

Do you expect the new layup with HS606 hubs to also pass UCI approval? Also is it possible to get the new big XMCS decals in laser-silver colour on the new layup wheels?

Our wheels can easily pass the UCI standard (40J), UCI approved stuff means nothing on quality point, it is only meaningful for selling and UCI race event. We will arrange more combo wheels for UCI approved though, including HS606 ultralite hubs too.  And yes all our decals can be applied onto all our rims.

We have arranged 50/50, 58/58, 65/65mm 26mm IW T1100 version built with R506 hubs 20/20H and carbon spokes combo wheels UCI approved, I believe they will be listed on the UCI official website soon. And the 58/58mm combo wheels are wind tunnel tested with very good result, compared with some other brands wheels.

Already got some good news, but really excited to know more detailed results, we just keep up our work to make high quality stuff.

Hi Peter, do you know whether Zipp ZR1 Freehubs can be installed on your wheels too?
I'm also aiming to swap the Shimano HG hub on my XMCS with the SRAM XDR hub on my Zipp Firecrest 404

Sorry, probably not

Hi, have XMcarbon 65mm deep 26mm internal wheels with Shimano XG. I need to change hub to Sram XDR. Do you know what hub i need to looks for? getting one from China will take a while, though i could use some DTswiss or smth

Original DT Swiss star rachets version freehubs are compatible with almost our hubs, except the non-released HS608 rear hub

Hello Peter, I am excited to see how the aero frameset performs. Hopefully, you saw earlier posts that toxin suggested about the fork area. After the wind tunnel tests, are you going to improve the frameset further or just release the frameset as it is?

Why to do that if the bike is fast ? The mold fee is not cheap.

Does this mean it will be available to buy after April? Or before?   

Size M and L will be available in April

Will you also take your other frames (and wheels) to the test?

Some 58mm wheels I think, but I don't think we would send other frames, since we will have this aero frameset testing compared with other brands fast bikes. Also we got quite a few feedbacks on our Gran Turismo bikes, fast, even endurance geometry.

I do wonder if Peter will use a full blown wind tunnel facility like Silverstone UK or the one down in Sydney Australia with the Nero Show dudes. Or just one of those janky portable wind testing machines like Winspace uses 

Haha. Silverstone wind tunnel testing it would be. We should be able to do this in April.
