Product description
The Shadow Interock 2 chain is re-designed with rounded side plates for compatibility with 8T and larger drivers. Extra wide and heat-treated mushroomed pins, stronger rollers and heat treated side plates provide maximum strength and durability.
New features include: tighter fitting bushings, center punched pins, and the side plates have been modified so that the chain will now work with 25-9 gearing.
This great new chain features T6 heat treated pins and plates. It also allows for 0.25 inch adjustment rather than 1 inch adjustment on all other chains. Basically its a chain made of half-links.
