Ashima Rotor Bolt Set

The Ashima Rotor Bolt Set provides reliable rotor fastening in two material options—7075 aluminum for low weight and steel for maximum durability. Both variants use standard M5 × 10 mm threads and Torx drive heads for secure installation. Aluminum sets include 6 bolts for a single rotor; steel sets include 12 bolts for two rotors, supporting road, gravel, and MTB use. Use a medium‑strength threadlocker and torque to your brake manufacturer’s specification (commonly ~4–6 Nm).

Aluminum (7075):

~6.5 g per set (one rotor)
T20 Torx head
optimized for weight‑conscious builds and XC/light‑duty
applications up to 160 mm rotors.

Steel:

~24 g per set of 12 (two rotors)
(~12g per rotor(6pcs))
T25 Torx head
best for long‑term durability and larger rotors.

• Rotor standard: 6‑bolt ISO rotors
• Thread: M5 × 10 mm (fits most 6‑bolt hubs/rotors)
