thanks for your replies -
with regards disc brakes - do you need to remove the rotors? - it will depend on which case I guess.
my frame will be ~59cm - from what i can see with the S&S 10” case the cranks could remain fitted but im not sure.
@Wefty with regards disconnecting brakes from the bike - you mean the brake/shifters from the bars? so would need fixing over the bar tape? otherwise any hyd brake disconnect would need a re-bleed?
i want the option of fitting a gravel/ higher volume tyre particularly to use this bike for that purpose instead of my road bike, one reason for going disc.
cheers
