Tools required:  ratchet ring removal tool, vice, a sturdy bench and a built wheel.


First you will need to disassemble the hub to access the ratchet ring.  Once the hub is disassembled set the internals aside as you will only be working with the hub that is laced into the wheel for the first steps.  NOTE:  Keep hub laced into wheel for ratchet ring removal.   For instructions on how to disassemble your hub please follow this link to Rear Hub Instructions


1. You will need to Identify your ratchet ring:   24 tooth shown in  (Fig. 1) or 48 tooth shown in (Fig. 2)

Note:  Do not mix the pawls and ratchet rings, mixing ratchet rings with different pawls will result in hub failure

2.  Install the ratchet ring removal tool so that flats are in the vice jaws.  Tighten the vice down to secure tool (Fig .3).

3. Place the built wheel/hub shell on top of the tool lining up the ratchet ring with the spline on the tool.  When in correct placement, the hub shell will be secure on the ratchet ring tool and the non-drive side hub shell will be facing the ceiling (Fig 4).  Once the wheel is secure on the tool, spin the wheel COUNTER CLOCK WISE.   If the wheel has been ridden it will be difficult to remove.  You may need an additional person assisting with the wheel to help loosen the ratchet ring (Fig 5).

4. Once the ratchet ring is removed, clean out the inside of the hub and make sure the hub and threads are clean of any debris (Fig. 6).

5. Take your new ratchet ring and with the chamfered side facing out, hand thread it into the hub shell (Fig. 7).  Make sure the ratchet ring threads all the way down until it is seated up against the internal face of the hub shell (Fig. 8).

6. After installing the ratchet ring,  rebuild the hub with the internals you set aside.  Caution:  Make sure to use the proper pawls with the proper ratchet ring (Fig. 1 and Fig 2).  The two tooth pawl must mate with the 48t ratchet ring and the one tooth pawl must mate with the 24t ratchet ring.  If they are mixed - the hub will fail.  See the Rear Hub Instructions if you need assistance with the hub assembly.   Once the hub is assembled, go for a ride!  Your first ride out will seat your ratchet ring in the hub and you'll be set to ride for many enjoyable miles.
