The KASK Nirvana aero helmet is claimed to save lots of Watts and provide you with a number of air flow. A cultured wanting helmet… however at a value. Our man is Spain, Alastair Hamilton has been fortunate sufficient to get his arms on one. Has it lifted his FTP? Are the Watts flying out? Or is the Nirvana only a snug, effectively ventilated and secure helmet? Here’s what he thinks…
Snug and tremendous aero
Sez: The KASK Nirvana is on the reducing fringe of aero bike helmets. In response to KASK “you narrow via the air with unparalleled effectivity”. Sure, I’m certain it saves some watts (a claimed 10.4 watts at 60kph), however the way it feels, seems, air flow and the protection concerned are factors which might be extra necessary to me – and if it makes driving simpler then that’s a bonus.
Seems good
The very first thing you discover in regards to the KASK Nirvana is that the helmet covers the highest a part of your ears, I’d suppose this is able to assist with aerodynamics, however can you continue to hear automobiles developing behind you? Sure, my listening to is simply the identical. Does the wind trigger any noise within the helmet? No, even right into a headwind, there was no air turbulence, noise or discomfort. The way in which the helmet covers the entire head does give a sense of full safety, this might be simply my feeling, however it’s definitely reassuring.
The ear overlaying shouldn’t be an issue
KASK additionally declare that there’s extra air flow than different ‘aero’ helmets. There are solely 4 vents on the entrance of the Nirvana, however they’re massive, permitting a whole lot of air to enter the helmet and your head. There’s a giant rear vent for the air to stream via. I’ve ridden carrying the helmet just below 20ºC and simply over 30ºC and on each events there was overheating, though I did really feel hotter when driving slowly.
Massive rear vent
Contained in the helmet there may be a whole lot of house between your cranium and the highest, which appears to let the air move via, plus the honeycomb 3D printed padding helps with this too. Air flow has been effectively thought via with this design and it really works effectively. There may be additionally a reflective strip below the rear vent for evening driving.
3D padding
These 3D printed pads additionally assist with security. Kask says they enhance the efficiency of the helmet in rotational impacts, they’re foremost reason for diffuse mind accidents. That is what the MIPS system additionally does, so prime marks for security. The straps on the ears are effectively positioned, though there isn’t any adjustment of the pacing of the straps. The a part of the strap below the chin appears like leather-based and doesn’t chaff and is adjustable.
Leather-based really feel chin strap
The retainer behind the top is absolutely adjustable up and down, much like most helmets and there’s a twist knob to tighten/loosen the grip. There isn’t a padding on the plastic retainer, in contrast to could different helmets, however I didn’t discover any issues.
Absolutely adjustable rear retainer
The entrance padding may be very gentle, which feels good in your brow, however did take in the sweat. This did cease it working into your eyes, however wanted drying out once you obtained residence. The form of the entrance of the Nirvana fitted my head form effectively, however in case you have a slim head, I’d attempt it first earlier than shopping for. I weighed the Nirvana and it was barely bellow the 270grm that KASK claims, however my scales should not the perfect. The helmet feels gentle, signal of an excellent helmet is that you simply neglect you might be carrying it after a short while.
Mild sufficient to neglect about
The Nirvana suits me effectively and I attempted a number of totally different sun shades and so they didn’t bump towards the helmet, even on tough roads. You may put your glasses within the vents, however I discovered they didn’t all match. It was additionally just a little difficult to get the glasses contained in the helmet and over the straps whereas driving. It additionally comes with a protecting carrying bag. I attempted arduous to search out one thing I didn’t like in regards to the Nirvana, however my solely criticism could be that it felt just a little free, it wasn’t and it didn’t transfer about on my head. Perhaps it’s simply extra snug than my different helmets.
Look good from the again too
To sum the KASK Nirvana up: It is vitally effectively designed and made, however the value is excessive, as you’ll count on from a helmet that’s made for somebody searching for each ‘Minimal Achieve’ doable. At first I believed it appeared a bit too android like, but it surely has grown on me, no unusual seems going into the cafe. Snug and lightweight and we’ve to consider KASK’s claims of aerodynamics. If in case you have the cash and need an aero helmet, then it might be the one.
I can really feel these additional Watts!
As with all helmets, we all the time advise that you simply attempt it on together with your glasses for the proper match.
