So ... being the wuss that I am, cba'd riding off road right now so little country lanes are a-calling.
My fave bike has tubeless mud tyres so that just sounds like a real draggy slog. FS is wearing Summer tyres, rear shock can be locked out but totally over-biked.
Option is to switch wheels and put a Summer tyre on the fave leaving a rear mud tyre to drag along.
Final option is to remove mud tyre on the ss front wheel and replace with Summer tyre. Rear always has a Summer tyre.
What bike for the easiest riding?
