Utilising many of the same features but with its own tread pattern, it\u2019s a surprisingly fast rolling, predictable and rather light bit of rubber. However, it\u2019s not quite the all-rounder of its Protagonist range mate.<\/p>\n
Cast Antagonist DualWall \u2013 Technical details<\/p>\n
Like the Protagonist, the Antagonist has been developed with a helping hand from Pirelli. As such, it gets many of the same bits and pieces that you\u2019ll find on a Pirelli tyre, such as the heavy-going DualWall casing, which has been built specifically for enduro racing.<\/p>\n
It\u2019s a 120tpi double-ply carcass that also gets a rubber insert just above the bead. This has been added in a bid to stave off pinch flats, while providing plenty of strength and support for aggressive riding.<\/p>\n

As for the rubber, this tyre uses the SmartEvo DH compound. It\u2019s a very soft 42 Shore A compound developed off the back of Pirelli\u2019s vast experience in motorsports.<\/p>\n
That\u2019s where Pirelli\u2019s hand in the process ends, as the tyre gets a tread pattern designed by Cast. It\u2019s a fairly tightly packed pattern built to inspire confidence when cornering, as well as create plenty of bite when braking. Because there are plenty of knobs across the breadth of the tyre, feel remains consistent as the tyre is tipped into a lean.<\/p>\n

The Antagonist is only available in the burly DualWall carcass and SmartEvo DH rubber, which makes sense for an enduro-focused tyre. It can be picked up in 29in and 650b sizes, though there\u2019s only a 2.4-inch width up for grabs \u2013 again, understandable.<\/p>\n
Despite Cast claiming a 1,250g weight for the 650b tyre I tested, I weighed it to be 1,182g, which really isn\u2019t too shabby for a tyre of this type.<\/p>\n
Cast Antagonist DualWall \u2013 Performance<\/p>\n
I\u2019ve been quite the fan of Pirelli\u2019s rubber compound and carcasses for a little while now, and previously, the SmartEvo DH rubber has been reasonably slow rolling. That is, until now.<\/p>\n
I was very surprised by the rolling speed the Antagonist encourages. It\u2019s not the fastest tyre in the world, but given its soft compound, it manages to add a spritely and easy-going feel to pedalling. That\u2019ll likely be because the tread pattern isn\u2019t the tallest around, but it is quite tightly packed. It\u2019s kind of like a much more aggressive semi-slick in the way that it looks.<\/p>\n
That tread pattern certainly gives the tyre a more rear-wheel vibe, which is how I\u2019ve run it, in tandem with the Protagonist at the front. But if you\u2019re looking to shed rolling resistance, it would make a reasonable choice up front, too.<\/p>\n

As there\u2019s not all that much space between knobs, it\u2019s mighty consistent in the corners. As it leans there are no dead spots or surprises, leading to a super confident feeling rear end. Encouraging it to break traction is no easy feat, either.<\/p>\n
Throughout my time with the tyre, I\u2019ve ridden everything from wet natural trails through to dry bike park tracks, and its performance across the spectrum has been very consistent. Thanks to the soft rubber it manages to find grip almost everywhere, making it a real contender as a year-round tyre.<\/p>\n

However, as that tread pattern is so tightly packed, it does tend to clog rather quickly in soft, wet and claggy conditions. Admittedly, this is the very limit of what the tyre\u2019s designed for, but in the UK, those conditions can throw themselves up at a moment\u2019s notice. Compounding that downside is that the tyre then struggles to clear that mud, reducing grip where you need it the most.<\/p>\n
Best mountain bike tyres 2025 \u2013 quality rubber for trail, XC and enduro<\/a><\/p>\n What I have been very impressed with is its braking traction. Because there are plenty of very sharp braking edges all over the tyre, it just bites into the ground, making for superb control when riding steep and questionable terrain. It\u2019s one of the few tyres that truly enable the full might of the very powerful brakes we\u2019re seeing crop up on the market. Yes, it can lock up under loads of power, but you\u2019ll need a very solid handful of rear brake to get it there.<\/p>\n As a more rear-focused tyre with that soft SmartEvo DH compound, it does wear relatively fast. After around four months of riding the tread is losing its sharp edges but, so far at least, it\u2019s still far from losing its performance.<\/p>\n Cast Antagonist DualWall \u2013 Verdict<\/p>\n \u00a380 is pretty much the going rate for good mountain bike tyres at the moment, though there are a few exceptions. Specialized\u2019s recent Eliminator Radial,<\/a> for instance, will cost you \u00a355. That\u2019s very impressive but, having ridden the older non-radial version, I found that traction wasn\u2019t quite as reliable.<\/p>\n
