Exploded views

This article contains exploded views of our current hubs and freewheels. The drawings clarify the structure and can be helpful when performing maintenance work.

The components numbered in the drawings are named in the text.
The assembly instructions must be followed! Failure to follow the instructions can lead to defects and injuries! If the necessary tools for correct installation are not available, the installation must be carried out by a specialist workshop using the appropriate tools!

Exploded view for front hubs

The following drawing shows the structure of the current generation of hubs with 17mm axle diameter: Exploded view front hubs

The hub consists of the following components:

  1. Axle with pressed-on end cap - depending on the version, suitable for the hub body and axle standard.
  2. 2x Bearing 61803 (17x26x5mm) - depending on the version, as standard, endurance or hybrid-ceramic bearings.
  3. Hub body - depending on the version for J-bend or straightpull spokes, with 6-Bolt or Centerlock brake disc interface and in different colours and hole counts.
  4. Bearing shims - the amount and thickness of the shims depends on the measured axle protrusion. The shim washers are used to adjust the axial play.
  5. Drive side end cap.

Exploded view for Cannonball hubs

The following drawing shows the structure of the current Cannonball hubs: Exploded view Cannonball hubs

The hub consists of the following components:

  1. Mandrel for the Lefty fork (not part of the hub).
  2. Spacer - simplifies the removal of the hub from the mandrel.
  3. Bearing 61805 (25x37x7mm).
  4. Hub body - depending on the version for J-bend or straightpull spokes, with 6-Bolt brake disc interface and in different colours and hole counts.
  5. Bearing 61802 (15x24x5mm).
  6. Fastening screw - secures the hub on the mandrel.
  7. Cover cap - serves as an abutment for the fastening screw when removing the hub from the mandrel. Attention: left-hand thread!

The Cannonball hub is shipped with shims. The shims are used to adjust the play of the hub on the Lefty mandrel. The shims are placed under the bearings to eliminate play.

Exploded view for rear hubs

The following drawing shows the structure of the current generation of hubs with 17mm axle diameter: Exploded view rear hubs

The hub consists of the following components:

  1. Axle with pressed-on end cap - depending on the version, suitable for the hub body and axle standard.
  2. Bearing 61803 (17x26x5mm) - depending on the version, as standard, endurance or hybrid-ceramic bearings.
  3. Hub body - depending on the version for J-bend or straightpull spokes, with 6-Bolt or Centerlock brake disc interface and in different colours and hole counts.
  4. Titanium drive ring - screwed to the hub body and can only be removed with a special tool.
  5. Bearing 61903 (17x30x7mm).
  6. Freewheel - see separate exploded view!
  7. Bearing shims - the amount and thickness of the shims depends on the measured axle protrusion. The shim washers are used to adjust the axial play.
  8. Drive side end cap - depending on the version, suitable for the hub body and axle standard.

Exploded view for freewheels

The following drawing shows the structure of the freewheel for the current generation of hubs with 17mm axle diameter: Exploded view freewheel

  1. Full-ball bearing 61803 (17x26x5mm) - Special bearing with increased load rating. A full-ball bearing MUST be installed at this position!
  2. Inner sleeve - only for Shimano Microspline and Campagnolo N3W freewheels!
  3. Axial locking ring - only for Shimano Microspline and Campagnolo N3W freewheels! The ring is assembled and disassembled with pliers for retaining rings.
  4. Bearing 61803 (17x26x5mm).
  5. Titanium pawls - 3 or 6 pieces depending on the version.
  6. Pawl springs - 3 or 6 pieces depending on the version. Attention: the pawl springs for freewheels with 3 and 6 pawls differ and are not compatible with each other!
  7. Freewheel body - depending on the version for different cassette standards and areas of application.
  8. Sprocket-stopper-ring - depending on the version for different freewheel bodies and made of plastic or carbon.
  9. Bearing shims - the amount and thickness of the shims depends on the measured axle protrusion. The shim washers are used to adjust the axial play.
  10. Drive side end cap - depending on the version, suitable for the hub body and axle standard.
When assembling the pawl spring, make sure that the orientation is correct, as shown in the drawing! An incorrectly installed spring cannot reset the pawl correctly and lead to defects!
