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

The towing bike must be approved for trailer operation. 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.

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 hub on your bike. Do not attempt to fit our adapter with a different thread size to your rear hub. An incorrect thread size can damage your bike. If you are unsure of 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!

The first step is to remove the M7 x 1.00 x 30mm cylinder screw (green), including the Nord Lock wedge lock washer and the bushing with the corresponding spacers [0.5mm - 4mm - 7mm] from your Rohloff Speedhub 500-14 / A12 gear hub.

Then reinsert the supplied bushing with the original spacers into your dropout. 

You must slide all the spacers that were previously on the original black bushing back onto our bushing. (green and red arrow) 

Now insert the thread adapter [M7 x 1.00 | M12 x 1.25] with the pre-installed Nord Lock wedge lock washer into the socket and screw it tight.

To do this, you will need a torque wrench with a hexagon socket attachment (6 mm wrench size); the specified tightening torque is 16-18 Nm.

Now you can screw the black spacer [4 mm] onto the threaded bolt using our universal adapter [M12 x 1.25]. You will also need a torque wrench for this (wrench size 17 mm).

But first remove the hexagonal screw [M8 x 16] and the two Nord Lock wedge lock washers from the universal adapter.

The tightening torque for this shouldNOT exceed that of the threaded bolt; we recommend a maximum of 16 Nm. You can insert a6 mm Allen key through the universal adapter (M8 thread) to tighten the threaded bolt. (lock nut)

You can then attach your coupling, the wedge lock washer with the larger inner diameter (ø10.7mm) is always behind the coupling, and the wedge lock washer with the smaller inner diameter (ø8.7mm) is placed in front of the coupling behind the screw M8 x 16mm, forming a sandwich, so to speak.

To tighten the coupling correctly (the interlocking of the wedge lock washers must be ensured), we recommend using a ring spanner ( 13 mm wrench size) or, even better, a ratchet with a 13 mm socket.

When tightening the screw (M8 x 16), make sure that the tightening torque is not transferred to the already tightened threaded bolt and adapter. To do this, you can secure the adapter with an open-end wrench (wrench size17 mm). (lock)
