Re machined 65 gears 
Idle gears 3 and 5
Sliding gears 5 and 6
 
Numbers 5,4,3 and 2 on the last picture 
 
All 4 gears are machined on all the contact faces with a perfect face to face finish,
We have ran theses all year on our own bikes with them being out of stock all over Europe  with absolutely no issues infract we believe our are more a perfect fit than new,
 
This is a exchange service so it the advertised price and your worn gear back back to us, If they have broke teeth we will not except then only worn gears !!
