i see, never mind nick, i shall explain MK1's they are 9mm deep rubber glued to faced old backings, these have been in used for around 4 months and i can assure u that its more than adiquate for strength. these while they last are £10 Mk2's are out soon, (take over from MK1's) the are the same rubber but in brand new backings made to fit perfectly, in my own way which im not going to release as its a Seriously quick and efficient way of makings pads, these will have 5mm of rubber for use but sell for £10 as we buy in the backings, so the cost is higher. these MK1's were made for friend initially and only friend could get hold of them Now following there success everyone nwants a pair (i dont blame them) so i am making a short video to promote these pads and will be available on MJCycles.com soon, Im sorry you cannot see exactly which pads is on Gaz's vid he made (cheerz) but i hope you can trust me and every other rider that these are out pads, and althought we no steve has an awsome pad out, we belive they are better. Thanx Mike
