That sounds like shite...im sorry, but that just seems impossible. I ran a tensile for about 18months, 1 skip.... If he IS breaking them.....then i suggest he should just jump a little before kicking? Adamnant don't make freewheels, it must have been an echo freewheel rebranded for some reason? no...it really isn't, you will eat shit if you've destroyed 4 of the most reliable freewheels in the world. How hard can you kick?! you must cane the hell out of them.... didn't realise anyone had killed an echo tr, let alone 3?! Also, how is your bb/cranks/chain surviving if youre raping the freewheels so fast? You should consider a career as a freewheel tester at that rate...
