I'll be running a set in XRRA this season
not completely true on the thoughts here
first - the airlocks (anytype) are only 1-2" larger in diameter than the wheel, so there's not a lot of exposed "balloon" to puncture. What's the chances of that branch goin in right at the rim?
Second - the tube is incased in a heavy duty nylon material that is very resistant to punctures and protects the tube.
Third - what do you do when/if you pop a tube and puncture it - replace the tube - alot easier that replacing and expensive beadlock rim. I got tubes at an atv store for $15each easy and cheap enought to carry an extra. Now your casing might have a hole in it but what's the chances of hitting that spot again in that exact hole in the rest of the event? they're warrantied so get it replaced when you get home.
Also compare apples to apple - these give you dual beadlocks - how much would that cost you?
I guess after you pull up the line and see 40 500hp rigs ready to rip the hell out of anything that comes in it ways, I dont want to worry about a beadlock wheel that might get a hole in it. I have bee around this for more than awhile, not trying to make anyone mad, just don't think some here have any idea what kind of speed we reach on some of theses tracks. I guess we will see, I wish all of you the best of luck this season, some times with out luck you have nothing at all. Again just my .02 worth.
