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
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.
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.
