LOL... Why bother though? Also, like Ian says, its damn hard to get that sorta pressure! What do you use... a rifle pump!? And what rim tape have you got on that Koxx rim... must be pretty strong to take all that pressure :- Im sure the Koxx rim isnt as tough as a 521... and Mavic reccomend a max pressure of 56PSI with a 2.0" tyre... Here it is...
I dont doubt the fact that you do pump up your tyres to 160 PSI (*snigger*) but if you are... then i suggest you stop - its fookin dangerous!!
