Yes, you can! The N3W freehub production license we authorize to third parties implies a geometrical respect that makes the match between their N3W freehubs and our AC21-N3W adapter. Some of the licensees might produce their own adapter since its drawings are part of the license too. For those who only produce the freehub... Campagnolo is here for you in case of need!

The N3W freehub was created to host cassettes starting with 9 and 10 sprocket but it opens us a wide range of future opportunities. At the moment we are focused on disc brake developments so only our disc brake future wheels will be updated to this standard. Our Campagnolo rim brake wheels will continue to use the classic Campagnolo freehub. We cannot guarantee the same for third party wheels so, in case you will buy another brand's rim brake wheel with the N3W freehub and intend to use it on a Campagnolo rim brake drivetrain remember to purchase the AC21-N3W adapter because all our rim brake drivetrains have cassettes that start with 11/12 sprocket.

Unfortunately no (the answer becomes yes only for certain Fulcrum products). We released our N3W standard for free and the drawings are public. All the hub/wheel manufacturers can adhere and produce our standard upon a licence request form to fulfill. What we force with our drawing specification is just the freehub outer geometry to match with our cassettes. Every hub producer then has a different interface between the freehub and the hub axle and its own engaging mechanism. That's why our N3W freehubs are not compatible with third party wheels. Please, check the list of N3W producers at the link above if you need a spare part for your third party wheel.

Absolutely not! We worked hard to spread our compatibility. You can find all the brands that subscribed our licence and are happily offering the N3W freehub as a standard in their wheel range here (bottom of the page, the list is constantly updated).

No, the existing wheels won't be directly equipped with N3W. They will be kept the same until the end of their life cycle and then replaced by new models N3W native. The main reason is that they were not developed as gravel specific products so we are not going to push their use with EKAR. We are riders though and we do understand the need of every consumer to save what they have already purchased and use it with a new drivetrain and the wish to switch the wheels between one bike and the other. That's why we created the conversion kits and the adapter.

No, the conversion kits AC21-N3WRFCC and AC21-N3WRFCS do not include the adapter AC21-N3W, and are provided only for fitting the N3W body on wheels designed prior to the 2021 range.

Any current wheel you want to convert to N3W, if you want to use it either with sprocket cassettes with the first sprocket with 9/10 teeth (such as Ekar or Super Record wireless) and/or any sprocket cassettes for previous drivetrains with the first sprocket with 11/12 teeth, you will have to order the adapter AC21-N3W.

You can find all the instructions at the following links: Retrofit Kit

All our existing disc brake wheels can be converted to N3W to make them compatible with 9 and 10 sprocket start (like our EKAR cassettes). Having a smaller ratchet diameter compared to the new generation wheels (30 mm vs 33 mm), these wheels need a kit (axle + endcaps + N3W freehub with smaller pawls diameter FH-N3WA30) to be converted: • AC21-N3WRFCC for cup-cone (ZONDA DB, BORA WTO family DB, BORA ONE family DB, SHAMAL ULTRA DB) • AC21-N3WRFCS for sealed bearings (SCIROCCO DB) ATTENTION: the only standard compatible with N3W is 12 x 142 mm. QR 135 and 10 mm axle are not convertible!

The AC21-N3W adapter will be already present in all the wheels that we introduce as road or all-rounder (endurance category), like SHAMAL CARBON, since they can be used both with drivetrains involving cassettes with 9 and 10 sprocket start, like Ekar (without the adapter), and with drivetrains involving cassettes with 11 and 12 sprocket start (with the adapter).

The AC21-N3W adapter package contains: • the adapter - a metal ring for length extension • the Z11 lockring - a longer lockring compared to the standard one that comes with the cassettes since it has to reach a deeper thread on the freehub after the ring installation. Lockrings that come with 10, 11 and 12 speed cassettes do not work when these cassettes are installed on N3W freehub + adapter as they won't SAFELY reach the internal thread of the freehub. Hence, the full adapter kit comes ready to fit all our cassettes starting with 11 sprocket (11, 12 and also 10 speed). For those wanting to assemble a cassette starting with 12 sprocket we have a specific lockring available as spare part
