Flat mount is new to me so I'm after confirmation of parts compatibility/ need before orders go in for a bike build.
Titus goldrush frame
Shimano grx rx400 rear caliper
Does a 160mm rotor fit the frame and do I need to also order a rear fm to fm +20 adapter in order for the caliper to fit the 160mm rotor?
Thanks
Depends on whether it’s a native 140 or 160 mount.
if the former, it needs the adaptor, if the latter, it bolts directly on.
Ha! Makes sense.
This one
I can't see of it says 140 or 160...I'm guessing 140 with no adapter.
The caliper is irrelevant, it's the frame that determines the native rotor size.
Is it, great, I shall check with px then.
Pretty sure the gold rush is 160 without using a rear adapter
Have you got the frame yet? Hope website has some technical drawings that give you the measurements to confirm which type of mount the frame is
