I finally have two options for the tyres:
Option 1:
Tyres Front: Schwalbe G-One R PRO 700 x 50mm
Tyres Rear: Schwalbe G-One R PRO 700 x 45mm
Wheelset geometry: Depth 45mm x inner width 24mm x outer width 31mm
Option 2:
Tyres Front: Schwalbe G-One R PRO 700 x 45mm
Tyres Rear: Schwalbe G-One R PRO 700 x 45mm
Wheelset geometry: Depth 45mm x inner width 30mm x outer width 36mm
Of course option 1 is risky, since it theoretically let me keep only 4,4mm clearance on each side at fork.
What do you guys think?
