2017 IRC Formula Pro RBCC tubeless road tyres


The IRC Formula Pro RBCC tyre has been revised. It is race tyre with the emphasis on wet grip and durability. This tyre is the ultimate all round race tyre. there are lower rolling resistance tyres but they tend to puncture more easily and don't have the same grip across a range of conditions. Team on Form have been testing these all year and on the 12 BORG50C wheelsets I have supplied. All the tyres are not close to being worn out. 3 tyres have been damaged by stones and need to be replaced but that is good a for a team with a full race schedule. Most of the tyres supplied will do a second season. 

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 tyres 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. The tyres also do not sit tall and this is useful for those running mudguards.

The teams experience and my own 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 are seen on the bikes of the womans team "Team on Form" as well as Nippo-Vini-Fantini.

25mm tyre 275g - real width on 17 to 19mm internal width rims 25mm and height 22mm. rolling resistance at 80 psi with 40 kg of load at 30 kph is 15.2W. Beware of comparisons, often higher unusable pressures are quoted.

28mm tyre 320g- real width on 17 to 19mm internal width rims 27.5 to 2mm and height 24mm. 

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.
