Jitsie Tr1al Freewheel

- Great value freewheel from Jitsie sister-brand Tr1al!
- Please note: Despite having "36 clicks" written on the side, these freewheels actually feature 30 engagement points.
- Two sets of ball bearings keep the freewheel running smooth, and help to eliminate flex which can cause skipping.
- The freewheel can be removed with a Shimano-style 20 spline bottom bracket tool. This allows it to be slimmer, meaning more clearance over your BB shell, and thus a shorter, stronger bottom bracket axle can be used.
- The lockring is on the back of this freewheel, meaning it fits up against your crank / hub when in use, meaning it can't work itself loose.
- Full hardened cromoly construction for maximum durability.
- 1.37" x 24tpi thread fits almost all hubs and cranks.
- 18T outer casing.
- Weight: 202g

Overall thickness: 18.2mm

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.

These freewheels may appear to 'rattle' from new - this is down to the bearing system. It would be possible to add an extra bearing in and stop the rattle, however this would then cause the freewheel to lock up!

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.

Hi Dylan!
Both the Jitsie Tr1al Freewheel and Jitsie 72.6 Freewheel will fit your Onza T-Pro fine if it's already got a front freewheel crankset fitted to it.
In the past Onza have made cranks with a replaceable threaded section on the cranks for the freewheel to screw on to. If, after you've removed your old freewheel, the new freewheel appears to be way too big to fit the threads, it will be because that insert is still attached to the inside of your old freewheel. This is fairly straight forward to solve, so if it happens get in touch and we'll guide you through it.
Hopefully this helps - if you have any more questions, please ask.
