When you're talking puncture protection and durability the Continental Gatorskin might be the ideal commuting tyre. But no-one would claim that it's a racing tyre - Conti aimed at maximum strength, not light weight.
For racing and training in all conditions you want to balance durability with ride quality, handling and weight... That's where the GP 4 Season comes in.
As seen, frequently, on the roads of Paris-Roubaix, this is basically the classic GP4000SII race tyre with added layers of protection.
The rubber compound has been tweaked too, to offer maximum grip in wet and greasy conditions.
So yes, it's good in the cold and/or in the wet, doesn't wear out too quickly, and has extra puncture protection, yet still feels more like a 'regular' tyre. It makes a lot of sense on UK roads, particularly in winter. We love it, and we're not the only ones.
"Puncture resistance is way above that offered by the fastest race tyres yet rolling resistance feels pretty similar. Grip is excellent, particularly in the wet."
