Thru axles are increasingly replacing conventional quick-releases on bicycles. Almost all well-known brands now offer this special fastening technology. This applies to numerous models, but especially to bicycle trailer hitches and adapters for e-bikes. For example, you will find thru axles with adapters for "Croozer" brand bicycle trailers as well as high-quality thru axles with polygon adapters suitable for Weber couplings type: E - EL - ES.
Weber: Safety meets quality
Weber Technik GmbH has been dedicated to innovative and high-quality bicycle products since 1985. Safety, durability and customer-friendly operation of the professional equipment are always the focus of the developers. Always at the cutting edge of technology, the products of the service-oriented company from Upper Bavaria combine maximum functionality with elegant design. All plastic components meet the highest standards - including couplings and adapters for bike trailers.
Fitting the bicycle trailer coupling on bicycles with thru axle
Of course, you can also get bicycle trailer couplings from other companies. This is also important. Unlike bicycle trailer couplings and adapters for bicycles with quick-releases, you have to attach customized bicycle trailers to bicycles with thru axles. Unfortunately, you cannot simply attach a trailer to your bike with a thru axle. You also need the appropriate spare parts with an adapter or coupling.
Let's first take a general look at the installation of a bicycle trailer coupling for bikes with thru axles. For the right module, you need to know the following parameters of your bike:
- Thread pitch
- Axle length
You can easily find out these figures on our Trailer Components selection guide website:
- Print out our specially designed PDF about couplings and adapters for thru axles in original size
- To determine the thread pitch and length, place your axle thread on the pattern
- Make a note of the numbers
Now you can replace the rear thru axle of your bike with the appropriate one to fit the required coupling. You may be able to choose couplings and adapters for bicycle trailers from the "Qeridoo" brand. Alternatively, other manufacturers have corresponding products in their portfolio. We at Trailer-Components also offer you high-quality, lightweight thru axles. This gives you three in one. Because they have
- Three different adapter heads
- All common thread pitches
- Installation lengths in millimeter increments.
This means you can find the perfect trailer quick-release axles for your bikes straight away, regardless of model and brand. Our universal products are compatible with all standard axle couplings and can be mounted directly on the solid axle or quick release. We also stock special adapters and couplings for the high-quality trailer couplings from Weber.
All thru axles with polygon adapter are suitable for the following Weber clutches:
- Type: E (Weber article number KU.02.000.00)
- Type: EL (Weber article number KU.02.100.00)
- Type: ES (Weber article number KU.02.200.00)
The following thread sizes are currently available:
- M12 x 1.00
- M12 x 1.25
- M12 x 1.50
- M12 x 1.75
The desired installation length of your thru axle can be selected with millimeter precision using the configurator in the article.
High-quality adapters for Weber bicycle trailers
Our customized Weber solid axle adapters with polygon guarantee a stable connection between bicycles and Weber trailer couplings in the thread sizes FG 9.5, FG 10.5, M10 x 1.00, M12 x 1.00 and M12 x 1.25.
All models are suitable for Weber couplings type E, EL and ES. You can determine the installation length to the millimeter.
If you are unsure, simply contact our experts without obligation! Maybe you don't even have a bike with a thru axle. If so, you can of course also order quick-release axles with polygon adapters in different clamping lengths from us. We have couplings and adapters for "Croozer" brand bicycle trailers in our range. And of course we can also advise you on special solutions.
