Finalized my build and going to pull the trigger on the frame soon. 7.3 Kg, less than 2k EU for the road build.
I wanted an lightweight "aero" race gravel frame that could double as a road bike, all with super limited budget. The choice of this frame was easy also due to the fact that in my size it has exactly the same geos as the Supersix Evo4 road bike so it should be good with a proper set of road wheels. For gearing I went 1x12 with 48 front and 10-44 on the back. I've been using recently my cx bike on the road and I've figured out that I want 1x my next road bike, might go for a smaller chainring for steeper gravel stuff, but for now the build is more road focused.
The groupset is a bit of a hack since I'm using Campagnolo Super Record EPS disc 12s levers with the electronic internals replaced by a 3D printed case for Sram AXS wireless blips, so that the lever paddle operates the blip in the lever. The levers are paired with ZRACE XG calipers so in the end they're lighter than the new Red E1 levers.
On the rear I'm going with the Rival XPLR derailleur to keep costs down, I really wanted to go 13 speed but the cost of the Red derailleur and cassette is bonkers, so I'll definitely wait for Rival or Force 13s to upgrade and to benefit of the UDH frame. There was also the option to go Wheeltop Gex with Ekar cassette, but it's also quite expensive and much heavier and I still don't trust Wheeltop. For the cassette I went Goldix as apparently shifts as well as Sram but it's 85g less than Rival.
Crankset is Magene PES because it just works and is very cheap, to save weight you need to spend a lot more if you need a powermeter.
I opted for a semi-integrated setup because I wanted to use the 34cm Balugoe handlebar I already have and I might change the postiton to fit better the situation.
The wheels are my favourite part as I can build myself so I went full custom with XMCS rims paired with Goldix hubs, went 21 spokes in the front to reduce drag and weight. Don't know yet whether I'm going tubeless or clincher GP5k since the rolling resistance is very close but the clincher is substantially lighter and cheaper.
Here is the Excel for the build, feel free to suggest some different parts. The main focuses are cheap and somewhat reliable. I'll post more once I start building the bike.
