Whether you're just getting into the thrills of mountain bike riding or perhaps you're a more experienced rider on a tight budget, the Motrip MTB Cycling Helmet has everything you need as you take to the swooping, whooping, twisting and turning of fun trails. The first-rate protection is made possible via the use of Abus' In-Mould construction. This sees a shock-absorbing inner EPS foam liner bonded to a tough and durable outer shell. In the event of an impact, the EPS inner soaks up and dissipates harmful impact forces. Meanwhile, the outer shell provides both structural strength and the durability to fend off the minor bumps and bashes you'll get from riding off-road. Zoom Ace MTB adjustment system A good fitting helmet is essential for both safety and comfort. And here the Motrip's Zoom Ace adjustment system makes it easy to get the perfect fit. With the rear dial and the built-in height adjustment, you'll be able to get a secure fit every time you ride. And with ponytail compatibility, long hair isn't going to prevent a good fit either. Cool Comfort As you build speed and confidence, you'll quickly be pushing your ride limits and working up a good sweat. But with 6 inlet vents and 8 exhaust vents you can look forward to cool airflow as you pick up the pace. Trail Ready The Motrip MTB features a height-adjustable visor, letting you get it in just the right place for your preference. In its uppermost adjustment, it also makes space for pulling up and stowing goggles, ideal for moments when you're taking stock, catching your breath, and readying yourself for the next drop-in.
The MoDrop MTB Cycling Helmet is your all-around trail lid with an outstanding price to performance ratio.

Should you find yourself caught out by gravity or a lack of tyre grip, the MoDrop provides reliable protection from head impacts. It does this via its Multi-Shell In-Mould design. At the core of the helmet is a highly shock-absorbing EPS foam, soaking up those damaging impact forces that come with a knock to the head. The EPS core is covered by a tough outer shell, directly bonded to it.

Whether you climb up to the trailhead or save your energies on the uplift, you'll soon be going downhill, and fast, with a huge grin on your face. XC, Enduro, 'Down-country', it's all about the thrill of the ride, and the Moventor 2.0 MTB Helmet (MIPS) is about keeping you safer when enjoying your mountain bike ride. Should you find yourself losing grip, exceeding the limits of your skills or clipping a handlebar it's the Multi-Shell In-Mould construction that provides the first line of defence in a head impact.

The inner EPS foam soaks up and dissipates impact forces while the outer adds structural strength and fends off minor bumps, from overhanging branches for instance.

For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head. Rotational motion is a common cause of concussions in oblique hits to the head. In a crash, the Mips system is designed to move slightly inside the helmet to help redirect forces away from the head. Safe and Secure Excellent safety is also matched with excellent comfort. A good-fitting helmet is essential for both safety and comfort.

In the event of a crash, this combination of durable outer and shock-absorbing foam liner dissipates impact forces, protecting your head from injury. Inside the EPS core itself, the ActiCage Lite system provides structural support and crash integrity, allowing Abus to strip weight, and optimise the size of the vents while making no compromises to your protection in the event of a fall.
