Chub Hub FAQ

How tight should I tighten the M10 titanium bolts to keep my wheel in the dropouts?

You need to follow our torque specification of 40Nm. If you still have trouble keeping your wheel in the frame, do not overtighten the bolts. Take your bike into your local shop so they can help diagnose your problem. You should use a torque wrench to ensure your bolts are tightened to spec.

Do I need to use anti-seize compound on the M10 titanium bolt threads?

Yes. If you fail to use anti-seize, commonly called Ti-Prep™, you risk the bolts seizing in the axle. Repair will be a time consuming and expensive endeavor.

Why is this hub so big?

In short, bigger flanges build better wheels. The large flanges provide more leverage on the spokes, which means up to 70% less spoke stress.

Why is the Road Front so small compared to the huge Chub Fixed Rear?

On a bike with either rim brakes or no brakes, the front wheel does not undergo the punishment the rear wheel sees from pedaling loads. In this case, we opted to save weight since we did not need the large flange diameter to decrease spoke stress. We did, however, make the flanges as far apart as possible to increase spoke triangulation which results in a laterally stiffer wheel.

Why is the disc side flange larger than the non-disc side flange on the Front Disc Chub?

Force transmitted from the disc brake system to the hub causes significant wear and tear on your disc side spokes. A larger flange has more leverage on the spoke. This means less spoke stress for a given amount of torque (ie, force input from disc brake system). We went with a smaller non-disc side flange to save weight and material.

What is the freewheel thread spec on the Chub SS/DJ?

1.375″ x 24TPI. The other thread-on standard (30mm x 1mm) is not compatible.

I have a Chub thru axle hub and need to get different endcaps, what do you offer?

In the past we have offered two different version of Chub thru axle hubs. While the hubs are similar, they use different flange, bearing, and axle sizes. The flange diameter is the easiest way to tell which hub you have if you don’t know, it is marked on the center tube of all hubs along with the other wheel building dimensions.

If your hub has 59mm flanges, we offer QR or 15mm endcaps. We do not offer 20mm endcaps for the 59mm flange hub.

If your hub has 73mm flanges, we offer 15mm or 20mm endcaps. We do not offer QR endcaps for the 73mm flange hub.

Can I convert my Chub SS front hub to a thru axle?

The Chub SS hub is QR only. For thru axle hubs we recommend one of our e*thirteen from hubs.
