Availability: In stock | Usually dispatched within 24 hours


This RS21 clincher wheel offers excellent quality and durability at a competitive price. Steel butted and bladed straight pull spokes with a 2-cross lacing pattern improve lateral and torsional (power transmission) rigidity. The elbow-less spokes make for a strong yet compliant wheel, and high lateral rigidity is produced with a 3mm offset asymmetric rim and wide flange spacing.

The hub uses angular contact bearings designed to cradle the balls giving both radial and lateral support for superior strength and durability in real world riding conditions. They also offer precision bearing adjustment and easy maintenance. The labyrinth and contact sealing - low-friction seals effectively shut out water, mud and dirt without affecting rotational smoothness.

Key Features:

  • Steel butted and bladed straight pull spokes
  • Elbow-less spokes make for a strong yet compliant wheel
  • High lateral rigidity is maintained by using a wide flange spacing
  • 8, 9, 10 and 11-speed compatible
  • Supplied with Q/R skewer

shimano rs21 wheels



The shimano rs 21 and rs 30 are very good wheels. I'm a bigger racer, my race weight is 200 pounds and so i need good wheels which usually last me 2 years before i pop a spoke. These wheels can't be beaten for the price
