These are good for DH
If you prefer to run tubes in your DH tires, these are the ticket! P.S. do not even slightly "preinflate" these if you are running them in 2.5" tires, it makes it very hard to seat the bead . If you leave them as is straight out of the package & then work them into the tire, seat both the beads, then it makes life good.
P.S. They are HEAVY! But isn't that the point?
