The Martello is Vittoria’s All-Mountain tire built to handle aggressive terrain. It’s a no-holds-barred assault on the demanding category with four rubber compounds and maximum tire protection available in the Vittoria technology arsenal. This new Graphene 2.0 version utilizes the wonder material, graphene to achieve better grip and better durability characteristics.
To state the obvious, it doesn’t look like a Maxxis Minion. In a category where everyone is becoming a look-a-like of the popular tire, Vittoria wanted to forge its own path. The company wanted to utilize its materials and expertise to develop a different tire. One that would be more consistent through a wider range of conditions. After all, the Martello designer and US director Ken Avery designed the original Maxxis Minion tire more than a decade ago.

Given that it’s not a Minion copy, it’s not easy to figure out and summarize this tire. Usually, one can just ride a tire a couple times and say, “Oh doesn’t grip quite as good but rolls a little better.”
So we gave it some time and really got to know it. It doesn’t have the sharp transition to the big side knobs that we’ve gotten used to. But one of our best bike handlers and testers, Travis Bertelsen, summarized it best after he bought the tire on his own accord and rode them with conviction. I asked him why he chose this tire and he said:
“My best friend Petey bought this tire and I got tired of getting my tail kicked on every descent. We’ve been riding together 20 years and he would separate from me on every corner, on identical bikes.” This happened after Petey bought the Martello G2.0 tire.
That’s high praise indeed, as Travis is one of the most brilliant bike handlers I’ve witnessed. It gave me insight and new confidence in this tire.
Where it excels
Its key strengths are cornering and braking in loose dirt, loam, loose over hardpack, gravel, wet and other tricky conditions. The Martello likes to search for the grip hidden under dust, sand or debris to claw its way around. And the grip is consistent from the middle to the side with always a couple knobs maintaining contact and handing off to each other.
Siping plays a key role too as these cuts in each knob give under pressure and effectively give a single knob more edges to find grip. Each knob typically has three sipes, increasing in width so they give at different points and progressively deliver more grip.
It doesn’t have a big blocky sharp-edged side knob like many enduro tires, so we don’t think it’s ideal for extremely loose, powdery conditions. Perhaps it can be relegated to rear tire duties there. To this tire’s credit, it doesn’t have that floaty transition between middle and side knobs either, or the falling off the edge of the side knob at the limit. Rather, it’s a consistent, confidence-inspiring grip.
On our test Stumpjumper Evo, we took off the stock Butchers and ran these for hundreds of miles. Improvement was dramatic as we took it to Lake Tahoe and our local steep fire roads and cornered better than ever with a predictable tire that had our back. Sand over rock, gravel over hard-pack and the usual scary stuff were both handled well in cornering and braking limits.
We kept lowering the air pressure to experiment but we never experienced a flat despite a few rim hits. The Martello may be heavy but the two-ply casing did its job. And when the tire bottoms out on the rim, there is a tire insert that will take the hit and prevent most tire pinch flats
Something we never talk about in mountain bike tire reviews is comfort. It’s a key attribute when reviewing road tires, so we know that it’s a key differentiator.
The Martello is one of the most comfortable tires we’ve used. Comparing identical tire pressures, of course, this tire seems to conform and absorb shock better than most other tires in the market. Perhaps the credit goes to the 120tpi casing or the dual-ply or the four-rubber compounds. We aren’t certain, but it is a smoother tire, in our opinion.
After approximately 800 miles of testing, our pair of test tires are worn, but in good shape. As expected, the rear tire is more worn with visible signs of siping wear, but both they look like they have more miles left in them.
Our previous Martello’s without the Graphene 2.0 looked pretty beat after a long weekend in Downieville, California, with its sharp rocks and shale. The new Graphene 2.0 Martello looks fine after a Downieville and a Tahoe trip. So we’re convinced the new compound makes a difference.
And one thing we appreciate is the side knobs have support structure foundation with a different hardness compound. Thus the side knob does not tear off or get undercut at the core after months of use.
And although they spell ‘tire’ incorrectly, the friendly folks of GMBN paint a very accurate picture of the people and infrastructure behind Vittoria Tires.
It’s not a Minion with the sharp edges that drop off between the center and edge knobs. This makes the Martello a great option in sand, loose-over-hardpack, and wet conditions, where predictable handling is key. It’s a bit heavy and not huge for its stated size, but it delivers consistent, dependable grip for many, many miles.
