Firstly I apologize for my approximative English.
I finally finished the buildup of my new gravel bike.
If it may help, as I found plenty of useful information on this forum, here is my contribution.
The configuration of the bike is as follow:
• Bike frame: Carbonda CFR 707 size L paint color RAL 7001
• Frame protection: clearprotect all over the frame and fork
• Bottom bracket: Shimano ultegra SM-BBR60
• Thru axles: Carbonda
• Front & rear shifters and brakes: Shimano GRX ST-RX600 and BR-RX400
• Rear derailleur: Shimano RD-RX810
• Front derailleur : shimano FD-RX810
• Crankset : Shimano FC-RX810-2 31-48, length 172.5mm
• Cassette: Shimano SLX CS-M7000 11-42
• Chain : KMC X11EL
• Shift cabling : cable housing Shimano SIS SP41, shift cables BBB speedwire BCB-36 and internal housing damper
• Handlebar: Ritchey comp butano 44cm
• Handlebar tape: Lizard skins DSP V2 3.2mm
• Stem: Deda superbox 80 mm
• Headset: Carbonda plus compression ring Deda DCR 45x45
• Saddle : Selle italia flite boost gravel Ti 316 superflow
• Wheels :
o Rims : Mavic A1022
o Hub : ZTTO R2
o Spokes : sapim Race
o Tires : Hutchinson Touareg reinforced tubeless 700x45
o Disc brake: Shimano RT-MT800 160mm (x2)
For the assembly I had no specific issue except the difficulty to find the appropriate stem in order not to have a huge gap just above the frame. I finally went with Deda superbox, which associated with the handlebar Ritchey Butano does permit to run the brake hoses fully internally in the stem and the handlebar, whereas the shift cable are semi integrated.
I run the rear derailleur cable fully protected in its hosing from lever to the rear derailleur.
I also protected the cable housing (shift and brake) with rubber damper to prevent any noise during ride.
I just have a little issue concerning the difficulty to adjust the brake caliper, as I still have very little disc brake chafing. I will see if after a little use I manage to adjust it properly otherwise I will have to grind the brake caliper mounting surface for the frame and the fork.
In the here above presented configuration and without pedals the bike weight is 9.325kg.
