The Haluzak Over/Under Idler Kit is for Haluzak bikes with fixed 8mm mounting studs on their framesets. With a high quality T-Cycle Over/Under Idler, a Stainless Steel Double-Sided Chain Keeper and the hardware to hold it together, this kit is ready to help upgrade your bike by maintaining your chainline.
Note: Some very early versions of the Haluzak have 5/16" shafts instead of 8mm. If this is the case, email us and we'll get you the right parts.
