4) USING YOUR TRAINER

GETTING THE BEST FROM YOUR TRAINER:

Do not ride your trainer with less than 1.5 complete turns (three half turns) of the roller 
adjustment knob after the roller first makes contact with the tyre.

 It is important that the 

tension between the tyre and the roller is set correctly every session for two reasons. (1) 
It ensures that the tyre will not slip on the roller which could cause permanent damage 
to the trainer and your tyre. (2) It ensures the resistance of your trainer is consistent for 
every training session allowing you to track performance. 
The trainer base power curves used in the JetBlack app are measured on a bike using 
700x23c slick road tyres at 110psi with exactly 1.5 complete turns (three half turns) of the 
roller adjustment knob after the roller first makes contact with the tyre. If your setup is 
different you will have a slightly different resistance, but as long as you keep the setup 
identical between each training sessions you will be able to monitor your performance. 

The proprietary fluid in the JetBlack Fluid Trainers increases resistance exponentially, the 
faster you spin the harder it gets. Correct use of your bicycle’s gears will allow you to fine 
tune any training session without having to manually adjust resistance. 
To make your indoor workout as quiet as possible, set the trainer on a JetBlack Trainer 
Mat and use a rear tyre with a smooth tread pattern. Once attached, the bicycle slopes 
downward slightly. To level, use the optional JetBlack Riser Block under the front tyre. 

CONSISTENT REPEATABLE TRAINING SESSIONS:

1.  Increasing the tension of the roller from our recommended 1.5 turns to 2 full turns will 

increase the resistance approximately 10-15%. If you are using the trainer for tracking 
your power performance, you should resist adjusting the roller up to 2 full turns. 

2.  For every 20 psi your tyre deflates you will lose approximately 5% resistance. Check 

your tyre pressure before every ride, making sure it is inflated to whichever comes 
first - the tyre manufacturer’s maximum recommended pressure or 110 psi (if your tyres 
will allow). 

NOTE: 

Fluid trainers require a warm up period of between 5 to 10 minutes. This is also 

great time for you to do your own warm up. Once the trainer has been running for 5 to 10 
minutes the resistance will be easier and more stable. Trainer power curves for the fluid 
trainers are measured after the trainer has sufficient time to warm up. You should avoid 
monitoring your performance during this warm up period as resistance fluctuates until the 
resistance unit is adequately warmed up.

5) BIKE REMOVAL

Undo the roller adjustment knob on by turning it anticlockwise 1.5 turns to back the roller 
away from the tyre. Hold your bike with one hand and with the other hand undo the drive 
side adjustment knob, turning it towards your bicycle frame. Now unscrew the outer 
adjustment knob until the axle support cups are unscrewed away from the bicycle. Now 
you may carefully remove the bike forwards or upwards, until it clears the trainer frame.

6) CARING FOR YOUR TRAINER

When used according to the manufacturer’s instructions and cared for with common 
sense, your JetBlack trainer will provide a lifetime of training.
Wipe any sweat off after a workout.
Keep the machine away from any corrosive substances, such as salt or other potentially 
hazardous substances.
If the roller darkens or shows black tyre build up you may clean it off with a cloth. This 
tyre build up can be cleaned with a rag by friction rubbing the roller with a side to side 
motion. The rubbing motion with a clean rag will lift the tyre build up off the roller. Do not 
use alcohol or any cleaning solvents on the hydrogel roller. A clean cloth and friction is all 
that is required.

7) STORAGE 

Caution! The trainer will become hot during use. Keep children and pets away and allow 
trainer 15 minutes to cool down before transporting or storing your trainer.
To store or transport your trainer:

•  Grasp the trainer frame by the adjustment bolts/axle support cups and then lift so 

that you can fold the legs together. 

•  Be careful when folding the legs to avoid pinching your fingers.
•  Store the trainer indoors, out of the rain and away from temperature extremes.
•  Keep the trainer away from any corrosive substances such as salt or other 

potentially hazardous substances.

1) WARNING

•  Read and follow all instructions concerning trainer setup and installation of your 

bicycle into the trainer. Failure to securely attach the bicycle to the trainer could result 
in serious injury to the rider or bystanders.

•  Remove all oils and moisture from the roller and the tyre before use.
•  Keep both hands on handlebar at all times.
•  Do not over-tighten the adjustment knobs. Over tightening may cause damage to the 

trainer or your bicycle frame. The clamp handles should be firm and secure. Do NOT 
force!

•  Regularly check your trainer, particularly the mounting system, for damage. If you think 

your trainer may be damaged, do not use it and contact your supplier.

•  Always take care when training to prevent children or pets moving close to the trainer. 

2) CAUTION

•  This trainer is intended for single-rider bicycles only.
•  Read and follow all instructions.
•  Before beginning each workout, be sure the bicycle is securely attached to the trainer.
•  Ensure you always use the trainer on a flat surface.
•  Do not put fingers, feet or dangling objects near any moving parts.
•  Do not attempt to dismount until all moving parts have come to a standstill.
•  Do not attempt to modify your JetBlack trainer.
•  Do not attempt to stop the resistance unit or flywheel manually.
•  Resistance unit can become hot enough to cause burns. Do not touch resistance unit 

during use and for some period after use, until it has had sufficient time to cool.

•  Keep children and pets away from the trainer during use.
•  Before you start any exercise program you should consult a physician. Should you 

become ill, feel dizzy, light-headed or nauseous while riding the trainer, stop riding 
immediately and seek medical attention. 

•  The roller adjustment knob must be tightened correctly to prevent damage to the 

trainer.
