K-Edge K-Edge ACS

The K-Edge ACS is an awesome product. It prevents chain suck and frame damage especially important on today's carbon frames. Chain suck can cause significant damage to chainstays, especially on carbon frames; it can also damage chains and chainrings. The K-Edge Dirt ACS attaches to the frame by replacing the 2.5mm drive side spacer and made from 6061 T6 heat treated aluminium and stainless steel. It uses an ingenious mounting mechanism - replacing on of the 2.5mm spacers found between the right-side bottom bracket cup and the frame on today's common outboard bearing cranksets.
