giro air attack shield 2015 v bontrager ballista 2015 v kask vertigo non aero helmet
my christmas presents under the tree have been put to use. here is a subjective completely personal unscientific opinion.
i say if you feel fast you are fast. yeah yeah
temperature of the head and comfort.
from the outset let me say it is summer here downunda.
therefore the hottest helmet has had only a couple of rides. the hottest helmet by far is the giro air attack.
the bontrager ballista is cool almost as cool as the kask. yet the ballista has few vents. the ballista also includes two inserts with one operating as a sweat divert. it therefore has a great cooling design.
the giro will have to wait for autumn. fall fall fall
sheesh
i find the kask the most comfortable as expected of their premium helmet.
cost
kask 350 /giro 300 /bontrager 200 aust dollars.
nb australian standards make our helmets heavier as our standard is tougher than others.
hey there good looking
i find the kask the nicest looking. the rounded shape and shield of the giro are .....polarising but gives the most purposeful look. the shield is either something that works for you or not.
the bontrager is more like the kask in overall shape but is still noticeably different as an aero helmet.
i like it if not quite as much as the traditional shaped helmet. .
fit on the vendetta and my noggin
both the bontrager and giro fit well on the vendetta with an adjustable harness height at the back of the head. both are 3 position style and clear the headrest in my case.
previous kask helmets could be made to fit the vendetta but so far i cannot get the vertigo to work.
they all fit well enough on my ahem ahem large size head.
speed
well i feel faster with the aero helmets and that surely is all that counts. vroom vroom listen to the noise right.
research says 16 watts and whilst i have power meters i cannot be bothered to scientifically experiment.
lest i find a confusing result
value and quality
kask is a nicely finished helmet and priced to match.
giro has come down in price as it loses market share and is of good quality. the lens is a class act as is the docking mechanism
bontrager is of lesser quality and finish but has the two interchangeable linings and a bag all for a reasonable price.
winner
well at this stage i would have to give it to the bontrager ballista with the caveat that i will do further testing of the giro as it cools down....unda.
based on year round comfort. sun protection with few vents. appearance. versatility. third party pro testing of aero advantage . value for money. inclusions.
