With any new invention, there are a lot of questions. We have gathered the most popular questions and their answers below. If you do not see your question answered, please email us at info@libertywheelsystems.com.

What is the weight of the system of the HubDock

It is a light weight system at 415 grams complete.

With what drive-train systems is this compatible?

The HubDock is compatible with Shimano/Sram 8/9/10? & Shimano 11. The HubDock is not compatible with Campagnolo. 10/11.

What are the build dimensions of the hub?

The dimensions of the HubDock is exactly the same as a stock Shimano system.

What spoke drillings will this hub come in?

24, 28, 32 road.

What is the hub engagement in degrees?

The Hubdock engages all 360 degrees.

Will there be a disc brake version in the future?

Yes, A mountain bike version is coming.

Will there be hub shell-only available if someone builds a few wheels for racing?

Yes, there be hub shell-only available.

Will there be a matching front hub?

Yes, my Quick Release Safety Skewer System is called The Pull-It.

Will you have wholesale pricing and distribution for bicycle shops?

As our production increases the Hubdock will eventually be wholesaled and distributed to bicycle shops.

Can you please explain in more detail why and how does the HubDock Axle System create a more stable ride?

When thinking Hubdock think through axle. The Hubdock axle attaches through the frame using a 10 mm alloy steel bolt, compressing two 7075 T6 aluminum pieces together making a solid axle giving the hub a solid environment to spin over with four sealed ball bearings spaced in a wide stance, two bearings on each side. It is a light weight system at 415 grams complete. Please note, the Hubdock system attaches through the frame dropouts rather than inside the frame dropouts, as a standard quick release, which only has 5 mm skewer that extends through the frame. The Hubdock is more substantial than any conventional quick release. The Hubdock rides like a through axle!

How many holes in the hub?

Please designate the number of holes you require. We can drill any number of holes you need. Do you need 24, 28, 30, 32? Please let us know.

What the the distance between the frame dropouts before and after tightening the Hubdock?

I think there needs to be some amount of compression as the wheel is tightened and I would like to know how much is required.

The HubDock is 130 mm and on the clamp down, compresses to the frame about 1mm total movement of the frame, to the hub axle.

Bicycle dropouts vary but are about 131mm spaced apart on average.

The HubDock uses a 10mm diameter combo axle internal cam clamp system.

This is much stronger than a standard QR skewer. A standard QR is only 5mm in diameter.

This system gives very good solid mount to the frame and you never need to readjust once it is pre-set for clamping down.

How does the drive side bolt to the frame?

The drive side bolts to the 10mm axle end with a nut and washer.

How does the cassette stay on?

The cassette is attached to the free-hub in the conventional manner.

Will it be possible to use an over-sized mountain bike axle?

The HubDock already has a stronger axle than any mountain bike’s over-sized aluminum axle

Has the system been tested in rain/mud?

The hub is sealed and works well in dirt, rain or mud environments.

With it being one of the most pressure bearing points on a bike, how does the HubDock hold up to the torque and stress put in it?

The HubDock axle forms a solid rigid axle when spun together by using a unique inner shoulder bolt system of a 7075-T6 aluminum axle sleeve and a 70mm tempered steel bolt that extends through the frame with a cam clamp at the end. This is much stronger than the 5mm skewer rod that is now used on standard QR skewers. The HubDock forms a stronger connection to frame and transfers torque better than any other QR system.
