Brake discs for bicycles

High-quality brake rotors from the bazaar ensure precise braking performance and reliable heat dissipation during every steep descent. By purchasing top-notch second-hand rotors, you can acquire lightweight two-piece rotors with an aluminum spider at a fraction of the usual retail price.
When choosing bazaar brake rotors, we recommend considering:

• Compatibility with brake pads: Check the rotor's marking – rotors labeled "Resin Pads Only" are exclusively for softer organic pads, while hardened rotors can handle aggressive metallic sintered compounds.
• Two-piece floating construction: An aluminum central spider connected to a steel braking surface with rivets prevents rotor deformation due to heat and reduces rotating mass.
• Matching front and rear rotor sizes: A common combination on mountain bikes is a larger front rotor (e.g., 203 mm) to handle the main braking force and a smaller rear rotor (180 mm) for better modulation.
• Center Lock nut tightening mechanism: For the Center Lock system, check the nut type – internal tightening (for a cassette wrench) for classic axles, or external tightening (for a bottom bracket wrench) needed for thick 15 mm and 20 mm thru-axles.
