what would be the mould recommended for a 2by - 48/31T? The new or the old one?

 The new 48T option supports GRX 50/34T, while 46T only supports GRX 48/31T. The 48T version is also compatible with 46T.

GRT in beach race config.

63.3WAM tires, 4mm clearance at the chain stays.

7.9kg excl pedals (and without storage door I see 😉).

And completed build

Man if the reach were a touch longer it would be the perfect bike. But it's way too short unfortunately. Any other options with similar geo (but longer) and 2x compatibility?

The reach is already quite long when looking at other western bike such as Specialized Crux at 395 (size M) vs a size 54 Crux (388)...It's not as long as some other gravel bike but it's not on the short side either. Finding 2x modern gravel race bike with good tire clearance is pretty much impossible these day.

If you'd plot the GRT against all competition it'd be a bit on the longer end.

For us we felt this was a sweet spot, where the frame works for people with a normal fit and also quite well for people who want to go a bit longer.

We didn't design the first XMCS aero gravel bike to be an extreme package, as it would alienate the 'customer in the middle'.

Like always, there isn't a single frame that works for everyone.

Having said that, the Belgium pro rider that will use the black GRT for beach racing 'only' needed a 120mm stem. Indicating to me that we got it in the ball park for more serious racers too.

I mean I get your point about wanting to find a happy middle ground, not too long not too short, but using pros as an example is a bit lazy. MVDP also rides a short fit with a 110 stem and wide handlebars, he's got an FTP of 450 and is one of the best riders in the world (I'd say despite his rather bad fit on the bike that he's used to from his CX days!). My power is 70W lower, I suck at racing compared to him, and I still need a much longer fit because I've got totally different body morphology. Many Uno X riders use the Ridley Noah Fast with long 150+mm Deda stems despite the longer fit of the frame and so on; it's like there's as many fits as there are riders.

I asked this some months before and didn't get an answer then, but has anyone built up this frame with a headset cover that takes exposed non-integrated brake hoses, something like what Mondince and Tideace often have for their frames? I am very much interested in buying the GRT but because of the shorter fit I can't use an integrated barstem (nobody makes them in 150mm+ stem lengths), and semi-integrated solutions like Deda aren't really cutting it because of the rather high stack of this frame. I'd ideally want to use something like a -12 or -17 standard stem with long reach handlebars, and route the cables externally up to the headset where they'd go in those little holes/slots.
