I think Im going to pull the spare out of that front fender carrier and check it. I understand they will will wear out in the front fender carriers from friction, I guess coating them with baby powder in the carrier is a good practice.
Here is the actual tube Ed29 gave me after the Adventure Challenge for the Mad Scientist Tire Academy Museum. This was supposed to be a tube for Milton's front tire, but as you can see, dry rot, seam separation, or whatever you want to call it, rendered this tube useless.
What if it was the only tube available? Patch kit, sure. Hey! is the glue tube dry too?
Keep in mind, this was a stored, "brand new" tube!
There are many techniques - but I'm currently using this:
(1) Examine each spare before the ride
(2) Douse each tube with talcum powder
(3) Wrap in Saran Wrap. This preserves the talc so the tube will be less prone to kink in the tire carcass when installed, and also help with friction prevention when being carried around as a spare on the bike.
I took a front spare and a rear spare on the ride (plus patches etc.), and as for this year's Uncle's Ride, I took 2 extra spares for each tire in the truck out there in case I needed to replenish the bike stock or loan to someone else.
EXCELLENT POINTS!!
i USUALLY replace the glue & tube annually
i think i will add a bit of powder & try the SARAN WRAP trick, as well
thx
