Hey Guys - Leaving for a 'spur-of-the-moment' camping trip & need some tubes. As the bike is only a few weeks old I haven't yet had the chance to assemble all the proper kit. The single bike shop in my area doesn't have any correct-size rear tubes in stock. Is there an alternate size that I can get away with using in an emergency? I know 21" front tubes can be used in a pinch on the rear but not sure if that applies to the beefy 150 series tire on the Katoom. Any ideas?
I have used regular sized (i think is 2 inch) rear enduro tube (18inch) and i shredded in a couple of hours driving on street a little aggressive. it was inflated to 34 psi. just my experience
I ran a front tube (90/90) in the rear on my SE for several thousand miles in Patagonia with a fully loaded bike and had no problems.
I've been using rear tubes for 120 mm tire width for a year. Yep, they do look small for a 150mm tire but hey, it's rubber, it expands... Actually, that's the size the KTM dealer sells here so I assume almost every 950-990 Adv down here are using them.
