FAQs

Is this rotor compatible with Centerlock hubs?

Yes, it is a 6-bolt rotor but can be mounted to Centerlock hubs using a standard 6-bolt to Centerlock adapter.

Can I use this for road racing?

Yes, the Catalyst series is UCI approved for competitive road cycling.

Does the 203mm size fit all mountain bikes?

No, you must verify that your frame and fork are rated and have the necessary clearance for a 203mm rotor.

What tools do I need for installation?

You will need a T25 Torx wrench for the 6-bolt hardware and a torque wrench to ensure proper tightness.

Why is the spider made of aluminum?

The aluminum spider provides increased stiffness and helps dissipate heat away from the steel track more effectively than a one-piece steel rotor.

What is the weight of this rotor?

The 203mm Catalyst Pro weighs 202 grams.

Troubleshooting

Brakes are squealing during use

Ensure the rotor is clean and perform a proper bed-in procedure to seat new brake pads correctly.

Rotor rubbing against pads

Check that the wheel is seated correctly in the dropouts and perform a caliper alignment to center the rotor between the pads.

Brake feel is soft or spongy

Verify that your hydraulic system is properly bled, as this is more likely a hydraulic fluid issue rather than a rotor performance issue.

Pros and Cons

Pros

  • Excellent heat dissipation for fade-free performance
  • Stiff construction prevents rotor warping
  • UCI approved for competitive cycling events
  • Durable stainless steel braking surface
  • Compatible with Centerlock hubs via adapters

Cons

  • Requires 6-bolt hub compatibility
  • Large 203mm diameter may not fit all frames
  • Single rotor per pack

Setup, Compatibility & Care

Installation of the 203mm Catalyst requires a 6-bolt disc hub. If you are using a Centerlock hub, you must utilize a 6-bolt to Centerlock adapter. Ensure that your fork or frame provides adequate clearance for the 203mm diameter, as this size is significantly larger than standard 140mm or 160mm rotors.

  1. Ensure the hub threads are clean before applying the bolts.
  2. Use a torque wrench to tighten the 6-bolt mounting hardware to the manufacturer's recommended torque specifications.
  3. Always "bed-in" your new rotors with fresh brake pads by performing a series of controlled stops to transfer a layer of pad material onto the rotor surface.
  4. Keep the stainless steel track free of oil, grease, and cleaning agents to maintain optimal friction levels.
