Safety Testing

Both models of Dashel Cycle Helmets have been Certified to EN1078 - The European Standard. The Carbon Fibre version is also certified to the South Korean cycle helmet standard and will be adding certification in other territories in future.

Dashel Cycle Helmets are therefore only intended for use in Europe and any country where EN1078 is the accepted standard. Any use outside these territories will be at your own risk and we disclaim all liability thereto.

EN1078 How have these helmets been tested?

To pass EN1078 cycle helmets are crash tested on anvils that mimic flat surface and kerb impacts. The helmets are tested at the front, back sides and crown. When crashed the helmets must not allow a force of over 250g to reach the head. In layman's terms, g is the amount of gravity the earth exerts on you when you fall. 

When taken as an average, Dashel helmets' impact results are 155g, so well below the standards set. 

The helmets are tested at temperatures -20 degrees and at +50 degrees. Therefore they are only proven to provide protection when cycling at temperatures in between this range.

Helmet Replacement

If you are involved in a crash, you must replace your helmet. Please contact and we will provide a return address for your helmet so that we can assess the damage and dispose of it responsibly. In return, we will offer you a discount off any subsequent purchases.

Measuring and fitting

Measuring your head

Measure the widest part around your head – this is usually approx. 1cm above your ears. If you don’t have a flexible tape measure just use a piece of string or ribbon and find a ruler.

The 2 models of Dashel helmets come in different sizes. If in doubt we would recommend going up a size:

Dashel Cycle Helmet 
Small (S): 54-56cm
Medium (M): 57-59cm
Large (L): 60-62cm

Carbon Fibre Edition
Medium (M): 57cm - 58.5cm 
Large (L): 59cm - 61cm

How to Fit your Helmet

Place the helmet on your head, push it down ensuring it sits level 1-2 cm above your eyebrows and does not tilt too far backwards or forwards. The helmet should feel snug but not constricting. Use the comfort pads to adapt it to your size

Tighten the chin strap, the 'Y' shape should fit just below your ears. The Fidlock clasp must sit under the chin and not on the jawbone.

Make sure the strap feels comfortable but secure. You should not be able to get more than one finger between your chin and the strap.

How to Achieve the Perfect fit

Also included with your purchase is a set of black 10mm wide pads. The silver pads already in your helmet are just 5mm thick. For a tailor made fit, mix and match according to whether your head is narrow, high or round.

The pads are just to make the helmet as comfortable as possible. They do
not contribute to the performance of your helmet in a crash, if you wish to
remove some completely then do so.

Remember a cycle helmet can only protect you it if fits properly. The helmet should feel snug but not constricting and sit level 1-2 cm above your eyebrows. Do not tilt it too far backwards or forwards. The Fidlock clasp
must sit under the chin and not on the jawbone. You should not be able to get more than one finger between your chin and the strap.
