So I was finishing my build today putting all pieces together on my Diverge 52 carbon frame when something come to my attention: the flat mount SRAM Red hydraulic brake calipers can barely clear the wheel spokes (about 1-2mm maximum) using 140mm Centerline X rotors on my CLX 32 wheelset (centerlock). Decided not to risk a disaster I put those 160mm old Ashima 6-bolt rotors mounted on a Shimano RTAD-05 adapter, so the brakes now clear the spokes (about 4-5mm) and the rear one clears the chainstay by about 2-3mm.
Here's my question: since I have no other disc brake bike to compare, is it normal to have such tiny clearances on a gravel bike? My original project would be using a 140mm rotor, will it rub the spokes when pedaling out of the saddle or climbing?
