Pirelli Cinturato™ GRAVEL RC-X 700x40C TechWALL X SpeedGRIP tyre
They use the same tread pattern as the Cinturato Gravel RC. The Cinturato Gravel RC-X is the answer to all the requirements of gravel racing in rougher terrain: speed on the flats thanks to the minimal central lugs and aggressiveness in the turns thanks to higher and more prominent lugs that ensure stability when cornering. TechWALL X's new tubeless construction features a reinforced and durable 60 TPI fabric that extends beyond the tread edge to provide even more sidewall protection, in addition to the existing toe-to-toe protection layer.The Cinturato Gravel RC-X tire is designed to conquer the most demanding gravel race routes for riders looking for the best performance in any competition conditions.
TechWALL Gravel X
Tubeless-ready shell construction specifically designed for gravel with a textile braid of 60tpi, which has a greater overlap of layers up to the sidewalls and with an additional protective layer around the entire perimeter from toe to toe against punctures.
SpeedGRIP
Pirelli has created a proprietary rubber compound that allows for better performance and energy transfer with less effort when driving on asphalt, gravel or more aggressive terrain. The SpeedGRIP compound achieves the same durability as its MTB sibling (SmartGRIP), as well as the same high level of wet grip and allows for more efficient energy transfer to reduce rolling resistance to a level similar to pure racing road tires. This high-tech rubber compound is the product of experience gained from the world of off-road racing circuits around the world, where Pirelli has its stable place on both 2 and 4 wheeled vehicles.

PSI - indicates the pressure to which the manufacturer recommends inflating the tire. 1 atmosphere = 14.7 PSI
TPI (EPI) - the density of the shell's skeleton fibres. The higher the TPI value, the more flexible and flexible the tire will be.
Kevlar tire - foot made of Kevlar fibres. The cover can be folded, so it is more practical when moving or storing. It is characterized by a lower weight compared to wire casings and a higher resistance to puncture.
Wire tire - bead made of wire. The shell is inflexible, it is heavier than the Kevlar one.
