Customer Reviews for Dexter Nucleon Diggity - White

Dexter Nucleon Diggity - White
August 26, 2019

Ignore the price, this is a good helmet

Really impressed with this helmet. I've held off doing a review until I've used it for a while, and it is very comfy even after several hours. Sizing is consistent with Premier and Schuberth. Really like the sunvisor, vents seem to function well in the heat. Haven't had any cold weather to really test the pinlock insert effectiveness yet. The open ear areas, ready for a coms system, means that the wind noise is obvious. No worse than the Schuberth, and much quieter than the Arai. Ear plugs or in-ear phones solve this, as with other helmets. The helmet is light and the aerodynamics are good so there is very little buffeting or torque when you turn your head. The visor is easy to use, with fine adjustment, but won't stay open on the smallest settings at decent speeds, it blows shut. So far not an issue as the venting is so good that riding with it shut, even through London traffic, has been OK. I like the chinstrap clip system, really easy to use in gloves. My only gripe is that the system doesn't include a loop that will fit over the helmet storage clip on my bike, so I have to carry the helmet when on the ferry, for example. Build and material quality is excellent. A couple of inserts have plastic edges you can feel as you carry the helmet, but nothing that contacts your head. I've had Laser, Arai, Premier (3), and Shuberth helmets before, and this is as good or better than any of the others, for half or a quarter of the price.

Excellent helmet

Felt great as soon a I put it on. Feels a lot lighter than my other helmets. Lovely snug fit so it doesn't move on your head and it's got a soft, comfy lining. Comes with pinlock insert too. An absolute bargain.
