MY23 Dissent Carbon Downhill Bike

Product Information

The Dissent Carbon is a fork that comes with a Reach Adjustable
headset. It is supplied with the middle setting cups installed, but
it also includes optional +/-6mm eccentric cups for adjusting the
reach according to your preference. The fork consists of various
components, including the stanchion, upper crown, headtube brace,
lower crown, and fork lowers.

Product Usage Instructions

1. To check clearance between the fork brace and the frame’s
   headtube, follow these steps:
   1. Set the stanchions to your preferred ride height in the
      crowns.
   2. Release all air from the fork.
   3. Compress the fork fully to the bottom-out position.
   4. If the fork lowers’ brace makes contact with the headtube, drop
      the stanchions in the crowns to increase the distance between the
      fork seals and the underside of the lower crown.
   5. If there is still interference, repeat step 4 until there is
      enough clearance to avoid contact with the frame’s headtube.
   6. If there is interference even when the stanchions are flush
      with the top of the upper crown, revert to the middle 0mm headset
      cups.

   

2. If there is interference between the headtube and fork brace,
   drop the stanchions within the adjustment range until there is
   clearance at bottom-out.

   

3. If the stanchions are fully dropped and flush in the crowns,
   and there is still interference, the -6mm setting is not suitable.
   Please revert to 0mm headset cups.
4. If there is space between the brace and headtube at bottom-out,
   you can raise the stanchions in the crowns to lower the ride
   height. Always check clearance after any stanchion height
   adjustments.
5. For Boxxer model forks, ensure there is a minimum of 2mm of
   stanchion above the upper crown.
