Just a thought - I got the Staun inner tube beadlocks, and they work great. There`s nothing visible outside, except the 2nd valve stem, which is tucked inside the wheel, about 1é2 way back - Really hard to see, unless you`re looking for it! I doubt I`ll have any problems with them, especially if you`re not stopped too often for other things. Of course they`re just an inner tube, not a separate metal piece inside, so may not be offside of the law anyway. Just my 2c.
