BOX Three BMX Specific 140mm Rotor Silver

The Box Three 140mm rotor is a BMX-specific disc rotor in silver, with a ventilated design that sheds heat fast under repeated hard braking. It uses the ISO 6-bolt standard and is sized for BMX racing, where low weight and consistent stopping both count.

Features

• Ventilation pattern moves heat away from the braking surface to fight fade
• Built for the braking loads and heat of BMX race tracks with steep hills and technical sections
• 140mm size saves weight over 160mm+ rotors
• Works with resin or metallic pads (pad choice affects performance and rotor wear)

Specs

• Diameter: 140mm
• Mounting: ISO 6-bolt
• Color: Silver
• Use: BMX racing, freestyle, dirt jump and park bikes with disc brakes

Fitment

Fits hubs with ISO 6-bolt disc mounts. Requires a disc brake caliper (post mount, or flat mount with adapter) and pads.
