Depending on your bicycle Belgium + may not be a good choice.
With 28mm I don't think they would fit on my road bike (28mm w/19mm wide rims barely fit). I got some HplusSon Archetypes coming in and at 23mm they might not fit either. May have to go back down to 26mm tires.
Hed Belgium + are really wide. They are on my gravel with 30mm tires.
Road bike I'd go C2s.
Maybe.
As far as performance and road feel, tires and tubes make more of a difference than rims.
