OK, I got the Sharktooth yesterday morning (a day late!) and then spent the remainder of the day very frustrated trying to fit it to my non-ST Evoline 2 helmet. Because my helmet is not the one specifically designed with the right cutouts in the right places to fit the battery (nape of the neck) and the speakers etc it would have required some major surgery to force these bits into the right places, which I was not willing to undertake. the instructions are far too brief and in 96 different languages!, and the photographs in the instruction booklet are useless as they are too dark and don't actually show anything.
So I went back to the shop I got the Sharktooth from and said, "here you have a go". They tried and couldn't get it to fit either, so they rang Shark and talked to them, and to cut a long story short Shark said that it couldn't be done without getting really serious with it.
So, the situation is now that I have a Sharktooth headset which is designed for a specific Evoline 2 helmet, but not the Evoline 2 helmet that I have got, and so it will not fit.
The place where I got it from has said that they will do a direct swap for a Scala Rider if I take the whole thing back today...which I am going to do at lunchtime.
So, to sum it up I am not a happy camper, and am seriously under-impressed with Shark, the helmet is great but their design philosophy leaves a great deal to be desired!
Typical frogs!
Cheers all
