Installation

NOTE: AFter you set the ”Critical Measurement,“ you will be left with a certain amount of room between the triple clamps for your bike's headtube and the headset. You will need to know the headtube length and the headset stack height to find this measurement. This is VERY IMPORTANT! The maximum amount of room between the triple clamps for our Chubby and Chubby LT forks are:

Dim B:	Standard Size	Long Size	Example:	Headtube Length	125mm
Chubby / Chubby LT	156mm	191mm			+
				Headset Stack Height	27mm
				Total Height	152mm*

* In the example above, this combination will fit a Chubby or Chubby LT Standard size fork.
