A fast-rolling central band features lower-profile, ramped knobs that reduce rolling resistance on transfers and fire roads, while providing a powerful and predictable biting edge for maximum braking performance when you need to shed speed in a hurry. As you lean the bike over, you engage the aggressive, taller side knobs. These shoulder blocks are specifically designed to dig into loose soil and hook up on off-camber sections, offering unwavering cornering stability and inspiring confidence to carry more speed through turns.This exceptional grip is amplified by the advanced tri-compound Race Ripost Gravity construction. This technology is engineered to manage rebound, ensuring the tyre remains planted and in contact with the trail, even through high-speed chatter and over roots and rocks. It precisely controls how the tread deforms under load, providing a supple feel with incredible grip across a wide range of surfaces. Durability is assured by the robust Hardskin protection, a bead-to-bead reinforcement layer that significantly increases resistance to punctures and sidewall cuts. This, combined with the strong 66 TPI casing, creates a tyre that can withstand the harshest abuse on the most difficult terrain. The folding bead and Tubeless Ready design allow for easy setup, lower running pressures for enhanced traction, and superior protection against pinch flats, making it a reliable choice for race day or any day.Technical Specifications:* Primary Discipline: MTB Cycling, Gravity, Enduro* Recommended Use: Rear Tyre / Aggressive Front Tyre* Size: 27.5´´- 650B* Width: 2.40* ETRTO: 61 - 584* Bead: Folding* System: Tubeless Ready* Casing: 66 TPI* Protection: Hardskin (Bead-to-Bead)* Compound: Race Ripost Gravity (RR Grav)
