Tyre Width 28 GP4000


Recommended Posts

I need a new set of road tyres and was looking towards increasing the tyre size.

If anyone knows,what is the actual width when pumped up to max pressure.

My fork on the BMC might be a problem

30mm width at 100psi

29mm height at 100psi on campy scirroco rims


i run them on a bianchi superleggerra columbus steel and there is no problem with clearance but tried them on my derosa superking 888 with cosmic carbon SL rims  - not a chance :whistling:
