        Installation

        Watch installation video:

        Super easy – no special tools required. You’ll need just a hex key or wrench.

        Step-by-step guide:

        1. Remove your current axle from the bike’s rear hub
        2. Compare thread pitch and total length with the new adapter
          • The total length should be within ±2 mm of your original axle
          • Some of our adapters include removable spacers – simply add or remove them to match the correct length
          • Make sure the thread type is identical
        3. Insert the new adapter into the hub
        4. Tighten by hand first, then secure it using a Allen key
          1. How Tight Should It Be?
            • If you have a torque wrench, we recommend tightening to 10–12 Nm (Newton-meters) – this is standard for most thru axles.
            • What if you don’t have a torque wrench? No problem. Here’s what 10–12 Nm feels like:
              • First, tighten by hand until the axle is snug and fully seated.
              • Then, with a standard 6 mm Allen key, apply firm pressure – like you’re turning a doorknob firmly, but not straining or using your full body weight.
              • It should feel secure, but not overly tight.
              • Tip: It’s always better to go slightly under-tightened than overtightened, especially on alloy or carbon frames.
          2. Attach your trailer hitch to the adapter’s end

        FAQ

        FAQ – Frequently Asked Questions

        Will this fit my bike?

        • If your bike has a 12 mm thru axle – most likely yes. This adapter fits 95% of all modern thru axle bikes.

        What if I buy the wrong one?

        • No problem – if you’re unsure, contact us first. We’ll help you get it right. (Free exchange inside Norway.)

        Can I install it myself?

        • Yes! It’s super simple. You only need a hex key or wrench.

        Will it fit my trailer?

        • Yes – it fits all bike trailers that mount on the rear hub (2-wheel trailers, not single-wheel cargo).

        Does it come with spacers?

        • Yes – many variants come with removable spacers to adjust length.

        What is a thru axle?

        • It’s a solid axle that goes through your frame and wheel hub – common on modern MTBs, e-bikes and gravel bikes.

        How do I measure my thru axle?

        • Remove the axle and check for printed specs. You’ll see something like “M12x1.5 – 172 mm”. Or use our guide.

        Can I use it with a quick release bike?

        • No – this is only for thru axle bikes. For quick release, check our 5 mm adapter.

        What’s the thread pitch?

        • It depends on your bike. Common are M12x1.0, M12x1.5 or M12x1.75 – let us help you check.

        Is it safe for children/pets in the trailer?

        • Absolutely. All our adapters are tested and safe for towing kids and dogs.

        Do I need a torque wrench?

        • Not necessary – hand-tight and secure with a wrench is usually enough. Check manufacturer guidelines for torque specs.

        Can I use this on multiple bikes?

        • Only if they have the exact same axle specs. Otherwise, you need one per bike.

        Does this work on electric bikes?

        • Yes – most e-bikes use thru axles. Just check the specs.

        What if my axle has no visible markings?

        • Send us a photo and we’ll help identify it.

        Where is it made?

        • Our adapters are made in Taiwan – trusted for high-quality bike parts.

        Can I use this with a hooded dropout?

        • Yes – our design works perfectly even on hooded dropouts.

        Is this compatible with Robert Axle Project?

        • Yes – we also collaborate with them for special adapter types.

        Do you ship worldwide?
