It's been a while, but I'm finally back with my finished build. After posting my story with the problem I encountered with my front wheel from elitewheels, they shipped me a new one while I was on vacation in Austria. A bit of a bummer I wasn't able to take the gravel bike with me, but the roadbike did just fine. After coming back yesterday, I completed my build. Also going tubeless for the first time, still unsure about tire pressures, as I'm running 2.2" in the front and 2.0" in the rear. Silca tyre pressure calculator suggested 1.4 bar in the front and 1.6 bar in the rear, don't know if I should go lower, but anyway - here's my full build:
frame: ordered from Tideace, size 54, color 58, with all mounts (I'm 178cm tall with an 88cm inseam)
handlebar: Lexon thin line (because I don't like the extreme flare the unox have), 400x80
groupset: Wheeltop EDS GX, carbon version
crankset: Riro carbon with 46t
BB: Ztto
wheels: Elitewheels Edge Gravel HOOKED 45, tubeless with Silca sealant and Ridenow valves
cassette: Ztto 11-50 11 speed
chain: Shimano 11 speed, waxed
saddle: Ryet 3D printed honeycomb
bottle cages: from a brand called HUALONG (but I'm sure these are sold under any other brand)
tyres: Continental Raceking 2.2" front, 2.0" rear
disc rotors: VXM in 160
I've spent some time calculating and checking my size, before cutting down the steerer. I'm really glad with my fit, did my first 50k testride, everything seemed good. The gearing seems good for my purposes, I can handle most inclines so far and I don't think I'm missing on speed when I'm descending. I've replaced every bolt I'm currently not using with nylon bolts I've found on aliexpress. I was first hesitant which groupset I should use - either Ltwoo gravel or Wheeltop - but someone, I think either gloscherrybomb or Uberflo - recommended the Wheeltop one because of the bigger cassette. I'm glad for choosing the Wheeltop one, because I really like the ergonomics of the shifters. I also tried flaring in the shifters for the first time, to see how much the difference is. That will be decided within the next few weeks, when I'm able to get some more km's in.
In conclusion: I really enjoyed my ride today, the bike feels like a weapon. Even on flats you are able to hold some speed, even though I have these chunky tyres mounted. I loved climbing and my gear range seems enough so far. I love how much of a difference this is in comparison to my roadbike. I'm really looking forward to tommorow's ride and the next few in the upcoming weeks. Thanks for everyone who contributes on this topic!
