I have an appointment to get my front tire replaced on Friday afternoon with a PR2. The dealer was telling me they have 3 options for balancing. The standard stick-on weights, balancing beads and a gel.
According to him, the beads are ceramic and go in the tire and are allowed to "float" in there and they dynamically balance the tire. Seems really strange to me, but he says it works great.
The gel he said is not like slime, but is a gel that will self-seal a hole up to 3/16" diameter and he recommends for people that commute all the time.
Anyone have feedback on either of the last two? They are both new to me.
