Road
GP5000 TL 28mm mounted on 25/32mm carbon rims
Gravel
Donnelly MSO WC 40
After riding the Clement xplor mso 36 for years and super reliable I recently mounted the new WC 40mm version and am loving them.
CX
Donnelly MXP 33 front and rear for most Ontario Conditions and rules
I have a set of specialized terras for mud that I run occassionally but they’re getting old so i’ll probably replace them with a PDX.
Like another poster said I think that the vast majority of racers benefit more from having extra grip than they would from minimal tread efficiencies.
MTB
Nobby Nic front, Racing Ralph rear. 2.3 I think. Hard to beat that combo.
