  Rotor Bolts for cranksets

  In this section, you will find original bolts for Rotor cranksets including 3D24, 3D+, Aldhu, Vegast, Inpower, and 2INpower, as well as bolts for chainring fixation on Rotor spiders. Since 2014, Rotor has used a softer alloy to manufacture its bolts, designed to protect the crank arms from wear and tear. These bolts are specially crafted to be softer than the cranks, preventing damage during assembly or replacement. Ensure your cranksets and chainrings are securely fastened with original Rotor replacement parts.
  These replacement bolts are the same original models fitted to your cranks during production. Choose Rotor bolts for reliable and long-lasting performance.

  Rotor Spacers — Precise Axle Play Adjustment (24 mm & 30 mm)

  Rotor spacers are simple yet essential components for optimizing your crankset installation. They allow you to fine-tune axle play, ensuring smooth pedaling without friction or unnecessary stress on the bearings.

  Compatible with Shimano Hollowtech II, Rotor Aldhu24, 3D24, INpower 24…

  30 mm Axles

  The spacer is usually installed on the left crank arm side, between the crank and the bottom bracket, to achieve a perfect fit.

  • Precise adjustment: eliminates lateral axle play.
  • Durability: reduces premature bearing wear.
  • Wide compatibility: road, gravel, triathlon, MTB (depending on bottom bracket standard).
  • Easy installation: simple to fit by hand or with a basic tool.

  Installation tip: start without pressure on the bearings, add spacers in 0.5 mm increments if necessary, then check for free rotation and absence of play.
