Description of Onza Porcupine MTB Folding Tire - 29x2.40 - white / skinwall

Rebirth of a legend

In the 1990s – the golden age of mountain bike sports - the former onza® team presented numerous innovative products to the bike community. Tire models such as the RIP, the DAVE, the RAIL, and of course the PORCUPINE were at the pinnacle of tire innovation in terms of grip and performance. After more than 30 years, it is time to revive the PORCUPINE’s legendary performance and achievements!

The PORCUPINE is back!

  • Modern, open and easy-rolling All Mountain tire tread.
  • The placement of the tread lugs is based on the appearance of a porcupine: Spiky knobs for extra grip. This corresponds to the idea of the PORCUPINE of the 90s!
  • Tire models with black and white tread rubber available, as in the 90s.
  • Various tire dimensions and widths available.
  • Casings in black and skinwall available for all tire sizes and widths.
  • New hotpatch design!

After over three decades the legendary PORCUPINE is back and get’s a complete makeover while still keeping it’s charakteristic look of the past. The tread pattern was updated for less rolling resistance and comes with a dual tread compound.

The PORCUPINE is the ideal allrounder that works in every situation, no matter the conditions. It offers a very wide application field ranging from Tour, All Mountain or even E-Mountainbike use with the GRC casing technology.

Key facts

High grip

The aggressive side knob shape paired with a soft 45a rubber offers loads of traction in every situation.

Low rolling resistance

Due to it’s center knobs and their ramped shape, the PORCUPINE is rolling super smooth.

Quick dirt shedding

The open tread profile with moderate spaces results in a great self-cleaning ability.

Class leading durability

To keep you out riding on the trail instead of wrenching the workshop!
