IRC Formula Pro Fusion X-Guard 28mm tubeless road tyre is the ultimate enduarance, commuting, audax or training tyre.
The IRC Formula Pro Fusion X-guard gives up a bit of grip and rolling resistance over the RBCC tyre for added puncture protection. The tyre has a 40×40 TPI puncture protection belt that cover the tyre bead to bead. This makes it a bit heavier but there is nothing better for high mileage riders or those that ride in the filth of a British or northern European winter.
While IRC do not say this in the literature the tyre compound is the same as the RBCC tyre so it is still a grippy tyre.
The natural latex lining is retained to improve comfort and reduce rolling resistance. This also means you can use inner tube patches with traditional glue to repair the tyre properly extending life.
The new tyres measure 25mm and 28mm on wide rims! Unlike most brands IRC know wide rims offer the best performance and a 28mm tyre that sits like a 31mm tyre is not going to fit in many bikes.
