FAQ

General

How do I check my battery status?

Both the handlebar unit and thru-axle have an LED that will light up upon shifting. The LED colour lets you know the charge state of the batteries. Additionally, you can verify the charge state by pressing the status-button on the handlebar transmitter or the thru-axle

What is the durability?

The Classified hub has an operational lifespan exceeding the lifespan of a bicycle’s internal systems, and it requires no maintainance.

Bearings are subject to normal wear and can be replaced.

If for any reason you think your Classified product isn't performing as it did when it was new, contact us and we will get you back on two wheels as soon as possible. (See service & spare parts)

If I want to service the bearing in the hub or driver, what do I have to do?

If you experience play on your Classified hub, contact us and we will get you back on your bike as soon as possible (see service & warranty terms)

What maintenance is required?

None. The hub's internals are desiged to be maintainance-free.

Wheel bearings are, however, subject to wear as with any other hub, and can be replaced. If you experience play on your Classified hub, contact us and we will get you back on your bike as soon as possible (see service & warranty terms)

What does it weigh?

Unlike most geared hubs, no weight is added to the bike. A Classified equipped bike is equally light or lighter than a bike with a traditional 2x electronic groupset equipped bike and traditional reference hub (eg. DT Swiss 350). To be more concrete, a bike equiped with Classified and 1x GRX Di2 weighs the same (+-10g) as a bike with a traditional 2x11 GRX Di2 groupset and a DT Swiss 350 hub. The bike setup used by our initial partner: Classified in combination with a Rotor Aldhu 1x crank, is up to 70g lighter than the same bike with a traditional 2x11 GRX Di2 groupset and a DT Swiss 350 hub. In short we can state that the weight of the replaced components (front derailleur, small chainring, traditional hub, thru axle and cassette) is approximately the same as the weight of the components offered by Classified.

Can I use it for bikepacking?

Yes! Classified hubs can be a great asset when climbing those steep hills with your bike fully loaded. If you're planning to ride for more than 3 months without going home, be sure to pack a micro USB charging cable so you can charge the Classified Thru Axle while sheltering from rain or checking in with your loved ones back home. You can be back on the road within an hour.

Will I need to replace batteries?

The battery in the Thru-axle is rechargeable. A fully charged battery will give you 3 to 6 months of use between charges.

The transmitter module in the handlebar has a coin cell (CR1632) and will last at least one full year before needing replacement. Replacing this battery is possible without having to remove your handlebar tape.

What is the lifespan of your cassettes?

Classified cassettes are machined from solid blocks of high grade tool hardened Chromoly-steel. This enables us to create lightweight cassettes with very high durability. Using a high-grade chain (see chain-compatibility section) will ensure you many kilometres of hard use.

Why does it only have two gears?

By offering 2 gears in combination with a regular derailleur setup, we can offer both a wide range and small gear steps just like you're used to. But by removing the front derailleur you get the dependability and performance you've always wanted.

Our goal is to optimise the drivetrain for performance. This means efficiency, durability and intuitive functionality. We see chain-based drivetrains as a solid platform to achieve this, but we want to remove its weakest link, the front derailleur, as it lacks dependability. Classified offers a wide gear range combined with small gear steps, which was only possible previously using a front derailleur. This is why the Classified hub is operated just like a regular 2x-setup.

Why is Classified better than a front derailleur?

Classified hubs replace the functionality of a front-derailleur, hence it's ratio is similar. Combined with our cassette options you can have both a wide range and small gear steps, while also retaining the big-step or bail-out functionality that you would have with a front-derailleur setup. At the same time it does away with chain deraillement typically associated with front derailleurs and thus provides more reliable, consistent and faster shifting under pedaling loads regardless of the circumstances you are in.

How quick does it shift?

Classified shifts faster than anything on the market.
The hub will shift within 0,15 seconds.

Can I shift under load?

Yes, Classified is unique as it can shift under load. You do not have to hold back, or stop pedaling to shift. It is designed to shift even under loads of up to 1000 watts. Futhermore, you can shift while coasting (and back pedaling). And even when standing still - the hub will complete the shift as soon as you start rolling. This all means faster, trouble-free shifting each time, over and over again.

Where can I get service/spare parts?

We want you to ride hassle-free. If for any reason you think your Classified product isn't performing as it did when it was new, contact us and we will get you back on two wheels as soon as possible.

How do I clean it?

You can use your normal bike-cleaning-routine, using mild detergents and a gentle hose down.

As for all bike equipement, we strongly recommend that you do not use any high-pressure or steam cleaning machines such as pressure washers.

Can I combine it with a Powermeter?

Yes, Classified can be combined with any crank or pedal based powermeters that fit your frame.

What size chainring do I need?

Classified hubs are optimised for chainrings from 40T to 54T.

Classified is designed to be flexible, so you can tailor it to your own needs. As a general guide, we suggest you choose a chainring similar to your current big ring for the same size cassette.

Please observe compatibility with your crank and also check for the required clearances for the chain and chainrings for your frame manufacturer.

Can I change my crank or chainring?

Yes, any 1x-specific crank that fits your frame is suitable to be used with Classified components. Minimum 40T chainring is required for Classified hubs. Always observe clearances for chain, chainring and frame parts as recommended by your frame supplier.

Can I use sattelite buttons to shift the Classified hub?

Yes, a satellite shift button is included when buying a Classified wheelset.

Can I also use standard wheels/hubs on my bike if I use a Classified hub

Yes, you will need to replace the torque insert on the left dropout with a conventional insert, which is supplied with the bike.
