Assembly instructions solid axle adapter universal
! WARNING !
The towing bike must be approved for towing a trailer. Riding the trailer with a towing bike that has not been approved by the manufacturer can lead to frame breakage or other material problems. This can result in accidents with life-threatening injuries.
If you are not sure how to install our adapter correctly, please contact a specialist workshop.
Our adapter must be fitted correctly. An incorrectly fitted adapter can come loose while riding and lead to accidents with life-threatening injuries.
Please note that our adapter must be screwed onto the thread of the bicycle axle with at least six full turns.
Less than six full turns of the thread will not ensure sufficient clamping force of the rear wheel, which can lead to accidents with life-threatening injuries.
You should definitely bear this in mind:
- Our adapters are only approved for bicycles and pedelecs (max. 25 km/h), not for S-pedelecs or e-bikes from 25 km/h!
- We would like to point out to all dealers and end users that they themselves are responsible for the entire bicycle trailer system and its correct functioning in terms of product liability!
- It is your responsibility to determine the correct thread size of your rear wheel axle on the bike. Do not attempt to fit our adapter with a different thread size on your rear wheel axle. An incorrect thread size can damage your bike. If you are unsure about the correct thread size, please contact us by email or phone and we will be happy to help you.
- cannot be used with bikes made of carbon or with carbon dropouts and carbon rear triangle!
- Regularly check the correct torque setting and that all components are free of play before using your bike in trailer mode!
- If you do not have a calibrated torque wrench for fitting our adapter, contact a specialist workshop.
FOR ASSEMBLY
IMPORTANT: Always mount the trailer on the left-hand side in the direction of travel!
Please remove the screw and the two wedge lock washers before you screw the adapter onto your rear wheel.
To tighten the adapter you will need an open-end wrench SW17mm, or if you have a torque wrench with a long 17mm socket, even better.
Please refer to the operating instructions for your bike for the tightening torque, usually 15-20 Nm.
Then you can attach your clutch, the wedge lock washer with the larger inner diameter(ø10.7mm) is always behind the clutch, the wedge lock washer with the smaller inner diameter(ø8.7mm) comes in front of the clutch behind the M8 x 16mm bolt, virtually in a sandwich.
To tighten the clutch properly (the engagement of the teeth of the wedge lock washers must be ensured), we recommend using a ring wrench SW13mm or, even better, a ratchet with a 13mm socket.
You should also bear this in mind:
All our Universal adapters have a maximum screw-in depth of 17 mm and must be tightened against the dropout (frame leg) using a force fit.
Therefore, check how long [mm] your threaded axle protrudes at the dropout.
If the distance is less than or equal to 17 mm, you can fit our Universal adapter to your bike without any problems.
If the distance is greater than 17mm, our Universal adapter will not be flush with the dropout (frame leg). You will need an additional spacer for this, which you can find from 2mm to 10mm here.
The be-all and end-all of our clutch connection are the two wedge lock washers from Nord-Lock, here you can see how they work.
