Yes , and they do an exellent job at it .
These guys are not amateurs .
If you are a paranoiac , maybe you could replace them by each tire change ?
I know others (Hobot ? ) tried to seal the rims in a different way , but if you have to use 300 grams of 'stuff ' to do it , whats the point ? . Plus , this is something I wouldn't want to experiment with ..
When shedding weight , it is VERY important to keep an eye on the suspended /unsuspended weight ratio .
I'm afraid this is where bwolfie is a little off track .
Your attention must go first to unsuspended weight , and more particular , the wheels .
That's why tubeless rims would be such an improvement .
A 330 lbs Commando with std wheels could become very uncomfortable .
If you have the money to shed 10 lbs off the chassis , or 5 lbs off the wheels , put your money in the wheels .
A lighter bike will always be more sensitive to road irregularities anyway , so you may soon find out that your good old Hagons suddenly aren't so good anymore . = more money ..
Remember the rules ..
