Mounting the Shimano and Campagnolo Sprocket

All the Forza wheels are equipped with the patented M-body, it is possible to mount Shimano 11 speed, Sram 11 speed as well as Campagnolo 11- 12 speed cassettes with this body. A Campagnolo spacer, before assembling the sprocket, is required before assembling a Campagnolo sprocket on the freehub. Slide the Campagnolo spacer over the freehub prior to assembling the sprocket.


Make sure the sprocket teeths are placed correctly to ensure proper working of the Hyperglide system. The Shimano/Sram significant starting teeth has to be located at the groove were ‘SHIM place here’ is lasered on the hub shell. Analog for Campagnolo sprockets, make sure the Campagnolo significant starting teeth has to be located at the groove were ‘CAMPA  place here’ is lasered on the hub shell. See the below pictures to clarify.

SRAM XD/R-driver body


All the Forza disc brake wheels can be upgraded to a SRAM XD/R-driver body for SRAM AXS 12 speed groupsets. The conversion to a SRAM XD/R-driver body only requires to replace the Forza M-body by the suitable Forza XD/R-driver body. The same end caps can be used, no additional parts are necessary.


XD/R-driver body shell greasing

Before assembling the Sram 12 speed sprocket, grease the hub shell thread with copper grease to increase the lifetime of your body and sprocket.



Replacing the M-body by the XD/R-driver body


Removing the end cap and sealing

  • Mount the two M12 Allen keys on both sides in the end caps to unscrew.
  • Turn both Allen keys to each other to loosen the end cap at the non-drive side.
  • Remove the end cap at the non-drive side by unscrewing them by hand.

Dismounting the freehub body and spacer

  • Remove the hub axle by pulling on the end cap at the drive side when tilting the wheel with the drive side to the ground.
  • Together with the axle, the freehub and the freehub spacer can be removed from the wheel.
  • Remove one by one the spacer, the freehub and the sealing from the axle.

Cleaning the parts

  • Clean all parts of the hub with paper towel.
  • Position the parts in the sequence as they came out the hub to remember the right sequence.

  • Turn both Allen keys to each other to loosen both end caps.
  • Remove both end caps by unscrewing them by hand.

 

Dismounting the bearings

All our Forza wheels are equipped with industrial deep grove ball bearings, special developed for bicycles.

Pay attention! The bearings are press fitted into the hub housing. They can only be dismounted using a bearing puller!

  • Apply the bearing puller in the bearing in the hub to dismount the bearing. 
  • Repeat this process for the bearing at the other side of the hub.

Cleaning the parts

  • Clean all parts of the hub with paper towel.
  • Position the parts in the sequence as they came out the hub to remember the sequence.

Remounting/replacing the bearings

  • Grease the bearing seats at the inner surface of the hub shell.
  • Put a new bearing, with the marked side to the outside, onto the bearing seat.
  • Apply the press fit to press the bearing in place.
  • Assemble the hub spacer on top of the mounted bearing
  • Repeat previous steps for the other hub side.
  • Grease the outside of both bearings.

Remounting the axle end caps

  • Screw both end caps on both sides of the hub by hand.
  • Mount the two M12 Allen keys on both sides in the end caps and screw tightly, by turning both Allen keys away from each other with 5 Nm.

 

ATTENTION

To reduce the friction during cycling you can remove the internal rubber sealing between the bearing and end cap. The end caps are sufficient to protect the bearings from normal weather conditions. When you use the wheels in wet conditions, we recommend you to not remove these sealings to increase the lifetime of the bearings.
