JT Coaster (Rocker Freecoaster)
We really had to think out of the box for this one. Freecoasters are notoriously difficult to set up and maintain, we had to come up with a design that was easy to personalise requiring virtually zero maintenance (in other words we had to hide the wizardry). After no less than 5 different prototypes around our chosen concept and many months of testing, we finally honed in on a detailed design that would work in production. The JT Coaster was born.
What is a freecoaster?
Basically speaking a freecoaster allows you to pedal your Rocker forwards as you would normally. However, when you go backwards i.e. fakie the pedals do not rotate, allowing you to coast freely in reverse (going backwards has always been EXTREMELY difficult to do on a mini BMX due to its small size and the riders natural centre of gravity).
Why do I need one?
The JT Coaster is set to revolutionise the mini BMX scene, making far more of your favourite BMX/Scooter tricks possible. It is ONLY available for Rocker BMX & IROK (you cannot buy a Mocker with this, nor will it fit a Mocker).
Can I buy a Rocker with a Freecoaster?
Now installed on selected models - look for the term “Coaster” in the title.
Can I upgrade my current Rocker?
Yes, the only Rocker the JT Coaster will not fit is the Rocker 1, however, if you have an IROK please remember that you will need to change your front sprocket to a 28T to get the correct gearing and for the chain to fit.
How to adjust your JT Coaster:
The JT Coaster features adjustable slack. Slack is the amount you have to rotate the pedals before the drive engages. More slack will make tricks easier as there is less chance of the clutch engaging when you don’t want it to. However, the downside to this is that it takes more pedal rotation to get moving again, which can be difficult to get used to (you might feel like the pedal has ’slipped’). Everyone is different and that is why we have included adjustable slack that is easy to adjust (no need to even remove the wheel).
On your JT Coaster hub, you will notice a little black rubber disk. This is the dust cover to the access hole through which you can adjust your hub slack.
- Pop off the rubber dust bung and put it somewhere safe
- Using your hands rotate the pedals forward until the clutch is fully engaged (wheel starts to drive)
- Slowly rotate your wheel via the tyre (not the pedals) whilst looking into the access hole. Turn until you can clearly see the ‘hard stop’ roll pin (looks like a little circle)
- Once you have located the role pin, look to see which setting you are currently running. You will note the plastic barrel adjuster, next to the roll pin you will see line(s) which represent the number adjustment e.g. 1 line = setting 1 (minimum slack) 4 lines = setting 4 (maximum slack). You might find using a torch helps you see exactly what's going on.
- Using a medium sized screwdriver push the barrel adjuster axially towards the driver side of the hub (the barrel adjuster is spring loaded and thus you will feel the spring's resistance when you push against it). Once it reaches its end stop, rotate left or right to select your desired slack setting, again looking at the number of lines to determine which slack setting you have dialled in. IMPORTANT, the slack setting lines MUST line up with the roll pin (little circle) otherwise you will not be running the slack setting you think you are.
Once you are satisfied you have correctly engaged the barrel adjuster to the desired slack setting, replace the rubber dust bung and test your JT Coaster again at the new slack setting. Try different settings until you are happy with the setup.
To begin with, most people prefer plenty of slack, so try it on 3 or 4 and once you get used to performing basic tricks without accidentally engaging the drive mechanism (caused by too much pedal movement during a trick), reduce the slack down to setting 1 or 2.
