Onza

Porcupine Gravity Tire, 29x2.60", Black

The Onza Porcupine Gravity Tire brings modern performance to a legendary tread design built for aggressive trail, enduro, and e-MTB riding. Designed to hold traction in loose, rocky, or wet terrain, it balances grip and control with dependable protection for demanding gravity riders.

Ramped center knobs keep rolling resistance low while maintaining consistent ground contact for efficient speed. Tall, widely spaced shoulder knobs bite into corners and shed mud quickly, keeping handling predictable across a mix of conditions. The GRC dual-ply 120tpi casing adds durability and pinch flat protection, offering the confidence needed for steep descents and rough lines. Tubeless ready construction makes setup straightforward and helps riders run lower pressures for improved traction and comfort.
