! WARNING !

Before you fit our thru axle with adapter, you must determine whether your bike is approved for trailer use. Check the operating instructions for the bike, ask the manufacturer or ask a bike dealer.

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 fit our thru axle with adapter correctly, please contact a specialist workshop.

Our thru axle with adapter must be fitted correctly. An incorrectly fitted thru axle with adapter can come loose while riding and lead to accidents with life-threatening injuries.

You should definitely bear this in mind:

Our thru axles with adapter 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 and installation length [mm] of your current thru axle on the wheel. Do not attempt to fit our thru axle with interchangeable system in a different thread size in your rear wheel hub. An incorrect thread size can damage your bike. If you are unsure about the correct thread size and installation length, 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 thru axle with adapter, contact a specialist workshop.

FOR ASSEMBLY

IMPORTANT: Always mount the trailer on the left-hand side in the direction of travel!

We recommend lubricating the thread of the thru axle with appropriate assembly paste before use to prevent friction, contact corrosion and wear.

The following Dynamic Bike Care products are ideal for this purpose.

To tighten the thru axle, you will need a torque wrench with a 6 mm hexagon socket.

Please refer to your bike's operating instructions for the tightening torque, usually 12-15 Nm for steel and aluminum frames.

You can then attach our Croozer adapter to the threaded bolt of the quick-release axle, but first please slide the Nord Lock wedge lock washer with the inner diameter(ø13.0mm) onto the protruding threaded bolt of the quick-release axle.

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 ensure that the tightening torque when tightening the adapter is not higher than that of the previously tightened thru axle.(12-15Nm)

To be on the safe side, you can counter-lock the quick-release axle from the other side with an Allen key SW6mm on the head of the axle to prevent possible transfer of the tightening torque when tightening the adapter.

Before attaching the Croozer drawbar, slide the fitting sleeve over the adapter.
The sleeve protects the adapter against unauthorized disassembly when the drawbar is locked.

Tip:

If you are traveling without a trailer, place the fitting sleeve in the trunk pocket of your Croozer trailer (where the buggy wheel belongs), or in the side pocket of your dog or cargo trailer.
This way you will always find the sleeve directly when you want to connect your trailer.
