Overview

This is the Center Lock version of the Carbon-Ti X-Rotor SteelCarbon 3, a very light disc brake rotor for road and gravel bikes, from 86g. It uses the same 1.8mm stainless steel braking track on a carbon fiber carrier. It is made in 140mm, 160mm, and 180mm, and arrives ready for a Center Lock hub with its adapter and a low-profile lockring.

Why we love it

We love that this one drops straight onto a Center Lock hub, with the adapter and lockring already in the box.

  • 01The steel braking track is 1.8mm thick with rounded, machined edges, so it stops well and sheds heat while staying light.
  • 02It comes with its own Center Lock adapter, a laser-engraved titanium protection plate, and a low-profile lockring, so it is ready to mount.
  • 03It was developed with the UAE Team Emirates World Tour team and race-tested at the Giro d'Italia, and that pedigree shows in every gram it saves.
Why it makes the cut. Hammer & Howl only carries parts we believe are among the best in the business. It is a clean, complete upgrade for a Center Lock wheelset.

  • Center Lock hubs built for 12, 15, or 20mm thru-axles (the included low-profile lockring suits all three)

Not compatible with

Confirm before ordering

If you are not sure which disc mount or rotor size your bike needs, confirm with your bike mechanic or contact Hammer & Howl before ordering.

Two things decide fit: the mount and the size. Your hubs need the Center Lock disc mount, and the rotor size you select must match what your frame, fork, and brake calipers are built for.

Moving to a bigger or smaller rotor can need a different caliper mount adapter.

The low-profile lockring in the box suits hubs built for 12, 15, or 20mm thru-axles. A Center Lock lockring tool is needed to install it and is not included.

If your hubs use the 6-bolt disc mount instead, choose the Carbon-Ti X-Rotor SteelCarbon 3 6-Bolt.

Questions

What rotor size should I choose?

Match the size your frame, fork, and brake calipers are built for, usually 140mm, 160mm, or 180mm. Moving to a different size can need a different caliper mount adapter, so check your setup or ask your mechanic.

Do these come with a lockring?

Yes. Each Center Lock rotor arrives with its Center Lock adapter, a titanium protection plate, and a low-profile lockring that suits hubs built for 12, 15, or 20mm thru-axles.

Will these fit my Center Lock hub?

Yes, if your hub uses the Center Lock disc mount. If your hubs use the 6-bolt disc mount instead, choose the Carbon-Ti X-Rotor SteelCarbon 3 6-Bolt.

Are these UCI approved?

Yes, they comply with UCI regulations. The disc profile has rounded, CNC-machined edges.

Will these fit Campagnolo or Fulcrum wheels?

Yes, if they use the Center Lock mount. Campagnolo and Fulcrum wheels built for the AFS disc mount are the exception: those need a rotor made for AFS, and this one is not. For an AFS wheel, choose the Carbon-Ti X-Rotor SteelCarbon 3 X-AFS. If you are not sure which disc mount your wheels use, check their specification before ordering.
