About the Onza Tyres Porcupine White

Free next day delivery on Onza tyres in the UK from Wheelie Bike Shop

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!

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-Mountainbike use with our GRC casing technology.
