I have both 650b and 29er wheelsets in the garage, neither are wide ‘plus’ size rims though but I at least have the option to experiment before getting some wider rims.
I imagine though that a 2.8” 650b plus tyre must be very close if not the same diameter as a 29er plus wheel?
Mine are a measely 25mm internal width (Enve M70), and have been fine with 3.0 tyres. Probably not 'perfect', granted, but I haven't ever had wider rims to compare against. Besides, the wheelset is too nice not to use.
Haha thanks but I’m way up in Scotland.
