Don't think anywhere does them because of the safety laws...
Lovely helmet though! Do you know why they were actually deemed unsafe? Looks fine to me, and my mate had one for skating, took a few bad bails and it held up fine..
Hmm never heard of that brand....
The easiest way to be 100% sure it is double walled, take off tire/tube/rimtape. You'll be able to see quite clearly whether its single/double walled.
And I don't think a dremel would be powerful enough?
Just do it. Don't think any of the newer denguras have had any problems, it's just the old ones give them all a bad name.
My guess is those 2 ^^ haven't even used the brake and are just slating it based on what they've read on here... You can bath bleed them and they are fine. Mine was. As was my mates...
Hmmm.... I have a similar model Toshiba and I don't get on with it at all. Hardware failure, flimsy charge jack (pulled out, snapped off etc) disc reader broke. Had it about a year, sent it off at least 5 times. Had a Dell inspiron, not had a single problem with it in 3 years....
Mike is right, But:
It's not just about you're riding level...
You need the right attitude, spirit, helpful etc.... Not all about free products you know, you gotta talk to people about trials, point them in the right direction etc...
