Is my maths/ guessing right- a 650b+ tyre at 2.8 will have similar diameter to a 29er 2.3 tyre?
I feel my 650b+ are a bit slow and draggy for marathons, so might get some 29ers with thinner tyres for this and keep the plus size for smashing round local rocks.
Absolutely don’t want to drop my bb anymore though
