Jitsie 108.9

17T
18T

Sold out

Now updated to a stealth black anodised finish for the 18t version! All other versions are the silver / black finish.

- High quality freewheel from Jitsie.
- 36 tooth ratchet ring with a total of 9 pawls provides 108 engagement points.
- Pawls engage three at a time, giving good reliability.
- Fitted with extra strong springs, providing more positive engagement, a louder sound and reducing bedding in time. Please note that this produces more 'drag' than a regular single speed freewheel.
- Four deep recesses in the main body save weight and increase BB clearance over 'external' tabs, and allow nearly all 4-prong freewheel tools to be used.
- Lockring on the rear of the freewheel faces the crank, so cannot not come undone when riding, and also means it can be used on rear hubs.
- 1.37" x 24tpi thread fits almost all hubs and cranks.
- Weight: 176g (18T), 168g (17T).

Overall Thickness: 17.2mm

This freewheel must be bedded in before trials use, to ensure any excess grease used when assembling the freewheel works away from the mechanism. You can do this by riding the freewheel around 'normally' for a few hours, both freewheeling and engaging the mechanism gently. If the freewheel is subjected to trials use without having been bedded in, the pawls will not engage correctly and this causes the freewheel to skip, damaging the pawls and ratchet. If you wish to speed up this process, you can thin the grease down with light oil like GT85 or WD40, by spraying it between the centre and outer teeth of the freewheel and rotating it. Failure to bed the freewheel in correctly will void the warranty.

Additional Information

Also compatible with SKF bottom brackets, however you may not be able to run a bashring with this setup - please contact us if you are unsure.

Can be used on the rear as long as you have a hub with standard 1.37" x 24 tpi thread.

Always ensure the lockring is kept tight, failure to do so may limit chances of any warranty replacement being issued. If you need help with how to do this then just give us a call!

Freewheel sound level:

All freewheels tested under similar conditions. Please note that the sound level of a freewheel may change after bedding in. A 10 dB increase in sound level is approximately equivalent to double the perceived volume.
