Careful with these.
I did extensive research and they could never give me a clear answer to the heat tolerance or speed rating of this process.
Plus the goop they use to seal the wheels will add weight and will affect the balance of the wheels greatly.
If one of these wheels do lose a seal it is complete loss of air very quickly.
Someone posted something about this a few years ago and lived to tell about it.
If you ever have to true the rims any movement of the nipples will break the seal. The original intention for the sealing method was created for Harley wheels.
Harley's barley sustain a extended 100 Plus MPH speeds for long periods. The heat and beating a wheel takes at those speeds are not intended for a sealed set of regular spoked wheel in my opinion
After the research and the pro's and cons of this I bought Alpina's
and eventually became their Distributor. I was a customer first.
I am not trying to sell you alpina's I am just a little skeptical with this process as they could never answer my questions about heat and Speed tolerance nor answer any liability issues.
Scary Stuff IMHO
In preparation for attending Reg Pridmore's school on the Streets of Willow at the end of the month, (and because Nicky Hayden didn't draw my ticket at Laguna Seca) I took my wheels and a set of Dunlop Q2s to Ride Wright Wheels in Anaheim, CA last week.
Naturally, the weather has precluded any serious runs on the butt dyno but I can say that the proprietor of Ride Wright, Mr. Sam Wakim is a pleasure to do business with and he sealed my rims for not much more than the price of a pair of tubes.
Anyway, about four pounds of inner tubes are in my garage instead of in my tires and as said before, if you are going to lose weight on your bike, there is no better place than inside the tires.
