SpeedGRIP compound sits at the center of what makes Pirelli's Cinturato Gravel M work across varied surfaces. Developed from Pirelli's rally tire program, the rubber formulation balances mechanical grip from the tread pattern with chemical adhesion to the riding surface. That dual approach means the tire hooks up on loose gravel where knobs need to dig in, but also maintains traction on damp hardpack and wet pavement where softer compounds would otherwise slide. This 2-pack provides a matched set for both wheels, packaged together for convenience when outfitting a complete build or replacing a worn pair.

The tread pattern uses medium-height knobs with deliberate spacing between lugs. The center strip runs nearly continuous for reduced rolling resistance on pavement and packed dirt, while the shoulder knobs provide cornering bite when you lean the bike over on loose surfaces. That spacing also allows mud and debris to clear rather than packing into the tread and turning the tire into a slick. Riders who encounter creek crossings, spring mud, or wet fall leaves will appreciate how the pattern sheds material and continues to grip.

Pirelli builds the Cinturato M around their TechWALL Gravel casing, a 60 TPI construction with reinforced nylon fabric extending bead to bead. The continuous protective layer adds puncture and cut resistance without excessive weight, addressing the reality that gravel routes often include sharp rocks, thorns, and debris that would shred a race-weight casing. The tubeless-ready design uses an aramid folding bead optimized for modern wide internal rims, and the tire carries hookless compatibility under current industry standards.... Read More
