I purchased a Mathews LX last year and have started having problems with wear on the string where it goes through the rollers on the riser. Now just so you know I have shot thousands of shots through the bow already. The string roller has worn shiny. There are no burrs on the roller. My bow mechanic has spoken with Mathews and they said that the LX should be set right at the ATA length that is specified so the string will have good pressure to remain seated in the roller. After making these adjustments , I noticed after shooting tonight that the serving was showing signs of freying I have only shot about 300-400 arrows since the adjustment to the ATA. Has anyone shooting the LX noticed any of these symptons. The LX is one of the ones that was changed after the original wear problem was noticed. So the bow has the updated rollers. The wear problem was noticed after I switched to a winners choice string. The string was reserved and now it is happening again. Winners choice serves the string alot further than the original string. Could this have something to do with the problem? The cam and the idler wheel seem to be in good shape and the bow is shooting awesome outside of the wear problem. Any ideas ?
