2017 IRC Formula Pro RBCC tubeless road tyres


The IRC Formula Pro RBCC tyre has been revised. It is race tyre with the empahisis on grip and durability.

The rice bran ceramic compound (RBCC) has been revised to improve wet grip. IRC claim a 4% improvement and a 10% drop in rolling resistance. These are race tyres and have been race proven in the U.K throughout 2017. After a season racing by Team on Form the tyre are not even close to worn and have helped the riders clock up wins. 

The tread rubber now covers more of the tyre so you can lean even further into a bend than you probably should. 

The natural latex lining is retained to improve comfort and reduce rolling resistance.

The Nippo Vini Fantini team wanted a file thread so IRC obliged.

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. 

My own experience with these tyres has been very good. Puncture resistance is very good and the wet grip is excellent. This is my favourite tyre and they will be seen on the bikes of the womans team "Team on Form" as well as Nippo-Vini-Fantini.

25mm tyre 275g

28mm tyre 320g

Why use tubeless tyres?

Tubeless tyres are simply better tyres well IRC are better tyres. Ride comfort is improved and is tubular like. Due to the lack of an inner tube rolling resistance are improved also lower pressure can be run improving grip. The latex sealant will heal most punctures.
