Novatec D981SB-CL Centerlock Disc Front Hub

The D981SB-CL is Novatec's thru-axle, Centerlock version of its front disc hub - a simple, purpose-built shell, since a front hub doesn't carry a freehub or cassette, just a well-sealed axle and bearing set spinning inside a Centerlock-splined shell.

It's built around a 12x100mm thru-axle, the spacing that's become standard on current road, gravel and endurance disc forks, and is offered in 24H, 28H and 32H lacing so it can be matched to the rim and spoke count you're building around.

It's a sensible pick whenever you're lacing a new front wheel, replacing a hub that's developed play or roughness, or standardizing a pair of wheels around the same axle and brake interface as the rear.

Why You'll Like It

Centerlock Rotor Interface
Swapping or replacing the front rotor is a lockring job rather than a six-bolt one, which makes routine maintenance quicker.

Standard 12x100mm Thru-Axle
Matches the front axle spacing used on the large majority of current disc road, gravel and endurance bikes, so it fits without hunting for adapters.

Three Lacing Options
Available in 24H, 28H and 32H, giving you room to match spoke count to rim choice and riding style.

No Wasted Complexity
As a front-specific hub it skips the freehub body and pawls entirely, which means less to maintain and one less point of failure up front.

Sealed, Low-Maintenance Internals
The bearing and axle assembly is sealed against road grit and water to keep rotation smooth between services.

Who Is It For?

This hub is for anyone lacing a fresh front wheel on a 100mm thru-axle disc bike - whether that's a full wheel build, a hub replacement on a wheel that's started feeling rough, or part of a matched front/rear hub upgrade.

On Indian roads, where front wheels take a steady beating from potholes and uneven surfaces, a well-sealed front hub with a simple, serviceable Centerlock interface is an easy way to cut down on unexpected maintenance between rides, whether that's a daily commute or a longer weekend route.

It also suits anyone standardizing a pair of wheels or a small fleet around one axle and brake-mount standard, since the same Centerlock/thru-axle logic carries over cleanly from the rear hub in this same Novatec range.

Good to Know

Use a Centerlock-compatible rotor and lockring for the simplest, quickest install.

Match the hole count (24H/28H/32H) to your rim's drilling before lacing.

A fresh coat of grease on the axle at build time helps the bearings settle in smoothly.
