Italian tyre big Vittoria won’t be as well-known within the mountain biking world as Maxxis or Schwable, however provides a variety of rubber to swimsuit loads of disciplines from highway to cross-country, and electrical bikes to commuters.
Its newest tyre, the Mazza, is designed particularly for path and enduro using, and encompasses a host of Vittoria’s personal tyre tech that ought to let it roll to the top of the pack.
I took to the paths across the Tweed Valley in Scotland to check out the tyres and discover out if graphene actually is nearly as good as claimed.

The Mazza is obtainable in two casing sorts: a lighter Path tyre, denoted by an anthracite-coloured sidewall, and a heavier, thicker Enduro and e-MTB tyre that’s all-black.
Each tyres have a 120 thread per inch (TPI) development and use the identical 4C Graphene 2.0 tread compound and tread sample.

Vittoria says that the Graphene 2.0 compound incorporates the tyre’s magic and that it “interacts with the rubber by filling the house in between the rubber molecules”. This, it claims, results in verified constructive will increase in a tyre’s total efficiency.
The two.0 model of graphene is claimed to go additional than simply enhancing the tyre as an entire, as a substitute it may be “functionalised” to spice up a selected space of efficiency, corresponding to rolling velocity, grip and puncture and put on resistance. Within the Mazza’s case, Vittoria claims the Graphene 2.0 improves all the tyre’s metrics.
That is performed utilizing a four-compound rubber, the place 4 particular person graphene compounds have been layered to tune the tyre’s really feel.
Vittoria says the floor of the tread stays cheesy, whereas the bottom has a stiffer compound, which ought to keep tread block form – and due to this fact how ‘sharp’ the tyre’s edge is – below excessive cornering and braking masses. Vittoria says this reduces rolling resistance and will increase put on life, too.

There’s no denying the Mazza appears to be like just like Maxxis’ ever-popular Minion DHF. Imitation, on this occasion, is for good motive, the Minion DHF has confirmed to carry out impressively. There are variations between the 2, although.
The Mazza’s centre blocks characteristic deep sipes alongside every tread block which, in line with Vittoria, ought to assist enhance rolling velocity whereas permitting the knobs to deform throughout cornering forces to supply cornering grip.
The bigger centre blocks that kind an alternating sample with smaller ones have a stepped forefront, which ought to serve to enhance mechanical pedalling grip whereas not lowering rolling resistance considerably. This acts as a hybrid answer between a ramped block and a square-edge one.
The braking edges of the blocks are sq. and Vittoria says it’s left loads of room for them to chunk into the bottom and clear mud when velocity picks up.
The facet knobs – that cope with cornering forces – are additionally closely siped and formed to supply an “asymmetrical tread flex”, which ought to make for predictable cornering. Just like the centre blocks, there are two kinds of facet block that alternate.
The bigger, outer-most block has a deeper central sipe and two smaller ones both facet, whereas the smaller blocks have three shallower sipes.
Vittoria says the 4C compound additionally helps to offer a sticky inside edge – the one which digs in on turns – whereas retaining its form because of stiffer rubber used elsewhere.
Vittoria Mazza 2.4 x 29in Graphene 2.0 4C tyre weights
The Mazza 2.4 x 29in Enduro and e-MTB casing tyre weighed 1,190g, whereas the Path casing 2.4 x 29in tyre weighed 970g.
The Mazza 2.4 x 27.5in Enduro and e-MTB casing tyre weighed 1,140g and the Path casing model of the two.4 x 27.5in weighed 930g.
The place ought to the Vittoria Mazza excel?
Vittoria says the Mazza is a mixed-terrain tyre, performing finest on hardpack, arduous/icy and moist terrain – rating 9/10 in Vittoria’s personal scoring system.
Whereas it ought to nonetheless have the ability to carry out in mud and on free floor, its efficiency isn’t claimed to be as excessive – getting a 7/10 on Vittoria’s efficiency rating.

I fitted the Vittoria Mazza tyres to 2 totally different bikes; a Marin Apline Path 8 with DT Swiss’s new EX 1700 Spline 29in wheels with an inside width of 30mm, and my Yeti SB165 long-term test bike with Race Face Turbine R 27.5in wheels, additionally with a 30mm inside width.
I fitted the Path casing Mazza to the entrance wheel and the Enduro and e-MTB casing tyre to the rear wheel. Each tyres on each bikes had been inflated to pressures related to the circumstances, starting from 22psi as much as 28psi.
The two.4in Enduro and e-MTB casing tyre measured 59mm/2.32in on each the 27.5in and 29in wheels when inflated to 26psi, whereas the two.4in Path casing tyre measured 61mm/2.4in precisely on each wheel sizes when additionally inflated to 26psi.
Tubeless inflation was impressively simple on the Path casing tyre with a excessive quantity observe pump, particularly on brand-new rims. On wheels with a number of dents or wider inside width rims – suppose 32mm plus – the Enduro and e-MTB casing tyre was tougher to inflate than the Path casing model, however after utilizing a tubeless inflator it seated on the take a look at rims pretty simply.
Throughout the 2 bikes, I amassed 784km of using on the Mazzas.

I examined the Mazza tyres on a number of various terrain in the course of the summer time in Scotland’s Tweed Valley, starting from sloppy, gloopy mud, greasy hardpack and rock slabs by to loam and dry and dusty floor with free rocks excessive.
The Mazza’s rolling velocity was spectacular and the sensation of tempo was particularly pronounced on fireroad climbs and flatter path centre sections moderately than all-out technical descents. On the climbs, it meant I used much less vitality to keep up the identical speeds in comparison with extra draggy tyres corresponding to Schwalbe’s Magic Mary.
These excessive rolling speeds had been welcome on the winches to the highest, however definitely got here on the detriment of braking and straight-line grip in sure circumstances on the descents.
As soon as the paths had been damp, particularly in the event that they had been a hardpack mud and rock combine and had grow to be greasy, the Mazzas struggled to keep up good cohesion ranges with the path floor.
Throughout cambers and over roots and rocks I used to be regularly taken unexpectedly when the Mazza stopped gripping with little warning, because the change from grip to slide occurred in microseconds.
This meant lightning-fast reactions had been required to maintain the bike on the proper line and made descending at velocity in these circumstances arduous work.
The low quantities of straight-line grip is also felt on damp rooty or rocky climbs. After I hit a root or rock at an angle, the tyres would slip alongside moderately than deforming and climbing over them.
Vee Tire Co’s Flow SNAP WCE tyre didn’t endure from the identical issues, gripping extra constantly and predictably on damp descents and climbs, and on the identical trails in the identical circumstances.
Braking grip over damp floor was additionally restricted. The Mazza’s tread sample and compound made them really feel like they had been gliding excessive of the terrain moderately than biting into it and when making use of the brakes, notably the again one.
The tyre was reluctant to supply a lot significant braking chunk except it was labored very arduous by being pushed into the bottom.
It felt just like the tyres had been counting on the rubber’s compound for grip moderately than any type of mechanical traction. Within the dry, the tyre’s efficiency was completely totally different, although.
The mixture of compound and tread sample seemed to be arduous sufficient and aggressive sufficient to chunk into and cling onto dry floor. I discovered that prime speeds had been accompanied by confidence as soon as I’d discovered dusty trails to journey.
Cornering girp – when it was dry at the very least – was additionally spectacular and constant, and I used to be in a position to predictably lean the bike over within the turns with out the concern of them breaking traction till pressured to take action. And as soon as I had initiated a drift, controlling it was comparatively easy.
In wetter circumstances, whether or not that was over hardpack or by muddier sections, cornering grip wasn’t nearly as good. I skilled fairly a number of situations of front-wheel understeer by flatter turns and the again wheel slipping up berms as soon as the tyres had been pushed arduous.
Dry cornering grip was generated by the facet knobs retaining their form below load – as Vittoria claimed – and their form offered a superb edge to chunk into the path.
I additionally discovered the Mazzas had a reasonably spherical profile even in 2.4in widths on 30mm rims, serving to to extend the quantity of lean I might obtain earlier than I reached the restrict of the tyre’s edge.
On softer floor – whether or not that was dry loam or damp dust – they gripped effectively, biting into the path’s floor with assertion, but it surely was at all times necessary to be careful for tougher greasy sections the place traction would drop considerably.
On the entrance, when getting used on an enduro bike, the Path carcass tyre survived loads of punishment with out ripping or tearing, even when subjected to very sharp shale-like rocks – beating Maxxis’ EXO+ casing for sturdiness on the identical trails.
Equally, the Enduro and e-MTB carcass, when fitted to the rear, shrugged off all of the punishment I might throw at it, proving to be extra dependable and puncture-resistant than Maxxis’ Double Down casing tyres.
Because of the carcass’s energy, I solely managed to burp the tyres a handful of instances, which galvanized me. Typically, the tyre offered a steady and predictable really feel when pushing arduous by berms – so long as they had been dry – with out the wander and vagueness created by thinner sidewalls.
Sturdiness has been good, though after 300km of using the rear tyre’s knobs are beginning to break free from the carcass on each take a look at bikes. This degree of sturdiness is usually higher than most different manufacturers’ choices in the marketplace in the identical sector.

Had Vittoria claimed the Mazza was for dry circumstances it will have been heading for a near-perfect rating as a result of it offered nice, predictable grip with excessive rolling speeds besides. Carcass energy and sturdiness had been spectacular, too.
Sadly, it claims it needs to be a do-it-all tyre that grips within the moist in addition to it does in different circumstances. I simply didn’t discover this to be true, particularly on damp hardpack mud and wetter roots and rocks. Traction ranges unpredictably dropped off in comparison with different all-rounders which, at instances, made for a bushy journey.
When you’re on the lookout for a fast-rolling, dry climate tyre, the Mazza needs to be excessive up in your checklist of concerns, however don’t anticipate it to be as a lot of a generalist as Vittoria claims, and for the autumn and winter you’ll be on the lookout for extra appropriate rubber.
