  • Overview

    Design by Matt Biolos and refined by his diverse stable of elite team riders, the new high performance MB fin is an exciting addition to the range and sits comfortably in the Carver family. 

    Featuring a wide base, curved trailing edge and a tapered tip, this fin is primarily geared for performance power surfing. The bottom half of the fin produces exceptional power and drive, allowing surfers to push hard through turns while maintain a feeling of stability in critical situations. The tip, which narrows significantly from halfway up the fin, offers the freedom and agility to turn abruptly with confidence.

    In contrast to Matt's original upright template (Reactor Family) that was loose and geared for tighter turns in beach breaks, the new MB template offers a balanced blend of drive, power and release that will suit more open-face waves and turns such as carves and power hacks. This fin also pairs particularly well with higher-rocker boards. 

    PC AirCore construction offers a stiffer flex allowing surfers to harness more power and speed when pushing ultra hard through turns.

    The quad rear template shares a similar outline aesthetic has been designed to work seamlessly with the side fins. As a quad this set will feel very stable and smooth to turn with an underlying feeling of control. The quad set is well suited to performance and hybrid shapes.

    • A serious-looking fin for surfers who take their surfing seriously. A no-nonsense performance fin you can use in any of the high-performance Mayhem models.

    • Expect a burst of speed from the first pump down the line, a feeling of stability when laying into a rail carve, and a surprisingly lively release action when pushing turns through the lip.

    Ideal Conditions

    • Open face, down-the-line waves, particularly good in point and reef breaks.

    Board Types

    • Designed to fit the FCS II Fin System.
    • Performance shortboards and hybrid models.

    Fin Family

    • Carver: Find Power. Powerful, drawn-out turns with added hold.

  • Performance Core Carbon

    Often referred to as PC Carbon or PCC, these fins are highly responsive and feature strategically placed carbon that’s designed to complement the fin template. PCC fins suit fast surfing and are favoured by power surfers who like to perform explosive turns on critical parts of the wave.

    Engine air filters are important!
    Size: 8.26" x 5.63" x 2.24"
    Just like me and you breathing, your car performs better when it can breathe freely and cleanly. My philosophy with an engine air filter is to replace with cheap and often. You can't control the quality of air coming into your system but you can control the filtering, so I'd rather replace the filter on an accelerated schedule with a cheap product than to invest into something more expensive and have it perform dirty for longer than it should. For my Honda CRV 2024 Hybrid, this filter fits snuggly and performs well.

    Good price
    Size: 26"/16"/13"
    Seems to be decent quality, only used them for a few weeks, but they’re doing a good job. Easy to install and can’t beat the price! I’ll definitely recommend them as of now, will update on the longevity.

    Worth the purchase!
    Size: 26"16"12"
    Perfect fit for my 2018 Subaru Crosstrek. Blades seem to be fairly durable. I live in the Pacific Northwest. So, they get a lot of use in the winter. I don’t expect them to last more than a years worth of use, but for this price I think it’s worth it. Maybe I’ll be surprised and they’ll last longer. No streaking so far after using them all winter. Well pleased with this purchase! Would recommend as an affordable, functional replacement blade.

    Quiet and easy to install on your car or SUV. Good quality blades.
    Size: 24"/18"/14"
    Wiper blades were easy to put on and come with an easy to follow instructional booklet. Wiper blades themselves are constructed well and made of quality rubber material. The other advantage is they come with all three blades which saves you time and money. Took about 10-15 minutes to replace all three wiper blades which can be done without any tools. The blades are quiet and so far do not cause any streaking. I recommend these blades if you’re looking for OEM quality blades that are easily replaceable and quieter than old blades that need replacing. They work well in heavy rainstorms.
