A light tubeless tyre for road racing or time trails from IRC. This tyre has low rolling resistance. There is no better tyre if rolling resistance must be minimised. 

Formula Light tyres 25mm 265g (verified)

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

The new tyres measure 25mm on wide rims (19mm internal width) ! Unlike most brands IRC know wide rims offer the best performance so size the tyres for these rims.

Compared to the RBCC tyre grip it has a bit lower but rolling resistance is lower also. Durability is still decent but as the casing is lighter, so is not as resistant to punctures or sidewall damage as its sister tyres. This is a racing tyre  for better roads. 

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.

For more detail on living and riding with road tubeless tyres have a read of this.

Please read this blog post before buying and check your rim is tubeless tyre compatible (and not just going with the manufacturers claim).
