just thought I wud add this for koxx bloxx/monty pads.. its from a post I did agesss ago but its more relevant here :-
ok before u do the whole wetting your rim thing take your koxx bloxx and cut 3 large X's across the surface with a hacksaw about 1.5mm deep.. then clean out all of the cut up plastic from inside where u cut cos it builds up. Then replace them on your bike and do the water jobbie.. BELEIVE ME THEY WILL WORK AMAZING! I did mine on sunday and they f**kin rule! THe problem with koxx bloxx is that they are completely flat so if u get any water or oil on your rim or even dust it all builds up on the surface of the pad.. The x's help to take some of it away and they work amazing
