Specifications

Why Upgrade to Floating Rotors?

Traditional fixed rotors are rigid — as heat builds during long descents, they can warp and create brake noise or inconsistent feel. Floating rotors use a two-piece construction where the braking ring can flex independently from the carrier spider. This absorbs thermal expansion, maintains rotor flatness, and keeps your braking feel crisp and predictable from the first stop to the last.

Frequently Asked Questions

Q: Are these BUCKLOS floating rotors compatible with all hydraulic disc brake systems?

A: Yes — the BUCKLOS floating disc brake rotors are designed for use with standard hydraulic disc brake systems on both mountain bikes (MTB) and road bicycles. They feature the IS/international standard 6-bolt mounting pattern common to most disc brake wheels. Always verify your wheel hub's bolt pattern before purchasing.

Q: What size floating rotor should I choose — 160mm, 180mm, or 203mm?

A: The right rotor size depends on your riding style and brake caliper compatibility. 160mm rotors are popular for cross-country and road riding where low weight is a priority. 180mm is a versatile all-rounder great for trail riding. 203mm rotors offer maximum braking surface and are ideal for enduro, downhill, or heavier riders. Many riders run a larger rotor (180mm or 203mm) at the front and a smaller one (160mm) at the rear for balanced control.

Q: Can I order mixed-size rotor pairs?

A: Absolutely! The BUCKLOS rotors are sold in pairs and you can select from six size combinations: 160+160, 180+180, 203+203, 160+180, 160+203, or 180+203. Buying a combination pair also offers better value than purchasing individually.

Q: Are colour options available for all sizes?

A: The standard colour is Black/Red and is available in all three sizes. Additional colours — Blue, Purple, and Gold — are available for the 160mm size only. Please add a note at checkout if you would like one of these colour options for your 160mm rotor.
