This is the Power Idler kit to seriously upgrade your stock sytem. Custom idler mounting brackets house a Terracycle Power Idler in Titanium cog. You won't believe how much smoother and quieter your bike will be until you install this kit and go for your first test ride.
Note: On older bikes with the square seat channel, you may need to trim the excess length from the right side seat clamp L bracket. Since TerraCycle idlers are larger for greater efficiency, this raises the chainline and may produce rubbing of the chain on the right side L bracket unless it is shortened. Rad-Loc seat clamp bikes are OK.
