We are now on our 4th design version of these pulley wheels and have constantly refined these over the last 3 years. 

The latest updated include : 

• Thinner top wheel tooth for sharper shifting.
• Custom specified bearing for us by Enduro Bearings.  
• Larger end caps with mechanical Labyrinth seal to hold bearings in place better and prevent grass build up.
