Interesting bit about tyre sealant voiding warranty, there are several on the market and we keep getting pestered to stock it, but I wont on the grounds of we`ve had a few bikes in with wheel balance problems at high speed and every time they`ve had this tyre sealant stuff in them, take it out problem solved.

Interesting one Mike - didnt notice that....

I did think the item on possible damage to a rear tyre after Dyno testing was interesting mind !
