More than 30 years ago, pointy Onza Porcupines were all the rage, offering some of the best grip of the day and the flashy combo of white tread on a natural skinwall casing that accented you brightly colored 90s MTB & even brighter purple ano components. Now the Porcupine is back, but in a much more advanced spiky tread design & modern construction  as an all-purpose all-mountain trail tire. You can even get it in white, or black if you aren’t feeling so showy…

The new Porcupine really shares only its name and all-rounder nature with the original Porc. This new trail bike tire is as precisely designed as anything we’ve seen from the modern Onza. Sure, it gets widely-space, spiky center knobs to dig into the trail, but the new tread design is optimized for excellent rolling too.

Tech details

Onza does a good job breaking down what each ramp, lug and sipe does to bring it all together. The result it seems, is a tire that should perform well across a range of hard & soft trail conditions, and can fit a number of trail bikes with 2.4″ & 2.6″ versions for both 27.5 & 29″ wheels.

…including some things we’d love to see become a trend in the industry – a recommended rim width (28-35mm internal for these) in addition to their tubeless-ready icon…

All sizes share the same TRC construction, a new name for Onza’s Trail Casing (previously called a FRC, Freeride Casing). The single-ply 60tpi casing is folded over the tubeless-ready foldable kevlar beads so you get two casing layers in the sidewall (plus an extra separate nylon reinforcement) and three layers under the tread for a balance of lightweight with abrasion & puncture protection.

The tires get an all-rounder Medium Compound 60 rubber – a dual-compound with faster-rolling, longer-wearing 60a rubber up top and sticky 45a rubber in the side knobs for extra cornering grip.

Not available yet this fall but probably expected in early 2020, Onza says a GRC gravity casing version will also be coming soon, as will a softer dual 50a/45a compound rubber option, as well.

Pricing & availability
