Onza

Porcupine Tire, 29x2.40", Black

The Onza Porcupine 29x2.40" Tire brings a proven all-conditions tread pattern to modern trail and enduro bikes. Designed for riders who want confident traction without sacrificing rolling speed, it balances grip, durability, and efficiency across a wide range of terrain. Its open, spiked tread digs into loose ground while maintaining predictable handling on hardpack and rock. Ramped center knobs keep rolling resistance low, helping the tire carry momentum on climbs and fast sections.

Available in two constructions, the TRC casing offers a lighter, single-ply build with reinforced sidewalls for trail riding, while the GRC dual-ply casing adds extra protection against pinch flats and sidewall damage for aggressive enduro or e-MTB use. Both versions feature a tubeless-ready bead for easy setup and a reliable air seal.
