Rock Exotica P21 Machined Mini Pulley

Rock Exotica's Machined pulleys start out as a block of T6 aluminum that is then milled for optimal strength. Also adding to the pulley's strength is the axle, which is an integrated part of the side plate. This integration enables the axle to include a custom threaded bolt that allows for a snag-resistant profile.


  • Recessed axle screw sits flush to pulley side plates, creating slim, snag-free profile.
  • Machined—not stamped parts, create a stronger pulley, increasing its strength-to-weight ratio.
  • Axle is integrated into side plates, adding additional strength and rigidity to the pulley.
  • Machined side plates allow for a more compact design while maintaining the same rope capacity of other pulleys.
  • Utilizes high-efficiency bearings
