I was wondering if anyone here has experience climbing with road-plus (47mm+) tires and standard road tires (23-28mm). I am looking into a gravel bike that comes with 47mm WTB Horizons on 650b wheels. The wheel diameter is very close to that of a 700c wheel with 28mm tires and the wheel weight is actually almost identical. The gravel bike’s overall weight is actually slightly less than the road bike’s weight.
That being said, I’m wondering if rotational weight comes into play on climbs and accelerations. Even though the wheel sets may weigh the same and have similar diameters, will the heavier WTB tires affect climbing/accelerations?
