– Nobblies look much more interesting.
– Nobbiles. More authentic, The great escape springs to mind.
– Nobblies are my choice, more in proportion to the frame.
Although some question the function of a nobbly tyres on a low bike with race posture and stance:
– The seating position is head down, bum up, which is best for high speed aerodynamics so it needs high speed tires. Knobblys suggest off road use, but the seating position means it’s difficult to stand on the pegs which you need to do for loose and slippery surfaces. It looks like the decision you have is whether to add tires that suit the shape of it or the probable use of it.
