OK I'm looking to upgrade the wheelset on my Airborne Guardian to something that is tubless compatible as I have not been able to set them up ghetto. I've narrowed it down to WTB i23 with X9 hubs or the Sun Ringle Charger Comps. Both are about the same weight and both hubs have sealed bearings the only real difference is true UST vs No Tubes BST. The only other difference would be that the Chargers would come out slightly less expensive because they come with all the necessary tubeless ingredients. So what is everyones thoughts on these choices?
