Hi
I am new too this site and i am after some help please with one of my bikes, This is a 2008 specialized rockhopper pro disk, probably a bit modern for this site ! ( I prefer Kona s early 90s ones ) any way i want to replace the crank rings on the specilaized as they re worn out ! Normally an easy job, but this bike has a hollow tech 1 crank I put a bar through the crank and put a crank extractor on it, it extracted the threads from the arm and thats about it ! has anyone any other suggestion to remove the crank arm ?
Thanks
