In the 1990s – the golden age of mountain bike sports - the former onza® team presented numerous innovative products to the bike community. The Onza Porcupine was 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! After over three decades the legendary Porcupine is back and get’s a complete makeover while still keeping it’s characteristic 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-Mountain bike use with our GRC casing technology.

Awesome tyre

I was suspicious that this tyre was aimed squarely at nostalgic 40 somethings wanting to relive memories of the must-have tyre from the 90s. I was correct, but this is 10 times better than the original. Mad grip in the corners, clears mud well and rolls fast. Seems like it's harder wearing than the original too, still early days though!
