Introducing the new IRC Formula Pro RBCC TL.
The flagship model that IRC have manufactured since 2008 has got an update for 2020. Not only does it provide excellent grip on all road conditions, from dry to wet, but it also succeeded in reducing rolling resistance.
New RBCC installed in all FORMULA PRO series products
The RBCC, which has gained tremendous support for its firm grip in cornering and wet conditions, has been installed in all products in this series. While maintaining rolling resistance, grip, abrasion resistance, and significant weather resistance have been improved. The compound that gives an absolute sense of security has been completed, such as the wider setting range of air pressure due to improved grip.
Adopted tread & pattern to enhance controllability
Continuing from the previous work, which was renewed from the slick, this time the center has adopted the Sugime pattern. The behavior near the limit, such as the start of tire slippage, is easier to understand and the controllable character is strengthened. In addition, rolling resistance was reduced by adding four grooves in the circumferential direction.
Compatible with disc brakes and wide rims
The tubeless tyre, which has a structure in which the tire bead is pressed against the rim from the inside with air to retain air, is characterized by high safety due to the high degree of adhesion between the rim and the tire, but with the new FORMULA PRO series, the key is Further strengthening around the bead. We have succeeded in further improving safety so that it can withstand the stronger force applied by the disc brakes and pothole impacts. In accordance with the tubeless rim standards reviewed in 2019, it is also compatible with wide rims.
25mm tyre is 270g, 28mm tyre is 315g and 30mm tyre is 330g.
80psi is the suggested max pressure. IRC state a max pressure of the sidewalls which half the max pressure at which blow off occurs in tests. I.e 90 to 115 psi means blow occurs at 180 to 230 psi. Hense my max suggested pressure. You dont need higher.
