Why We Like The PEAK 4550 Tune Disc Brake Wheelset

Light, stiff, and strong. That's the PEAK 4550 Tune Disc Brake Wheelset, and you bet it's a match for world tour and grand tour racing. Pro cyclists choose this wheelset for its aerodynamics, and they keep it around for its exceptional handling. It's uber lightweight and responsive for intense climbs so we can blast up mountain passes instead of trudge up them. We like that we can take tight turns with speed when we're barreling downhill, and that this wheelset is practically impervious to the crosswinds we face on flats and in valleys.


  • A race-ready wheelset for big tours and top tier cyclists
  • Aerodynamic capabilities make for wind-slicing speed
  • Superb handling comes in handy on descents
  • Aero design fights off crosswinds on the flats
  • Lightweight while still maintaining stiffness
  • Sapim CX-Ray spokes reduce rider fatigue
  • Item #PCS000D
