Fulcrum's Racing Speed XLR 50 in limited edition 'Dark Label' version featuring black hubs and a stealth graphic package


The Fulcrum Racing Speed XLR 50 has a deep profile, one that offers not only extreme aerodynamic advantages but also a larger rotating mass capable of maintaining the high speeds of flatter races, time trials and triathlon cycling legs. Despite their deep profile seemingly adept at flatter terrains the 1325gr weight for the pair make the XLR 50 a viable solution even for courses involving a great deal of climbing. The 17C internal width makes these wheels perfect for 25 and 28mm tires, for surefooted high-speed descents and cornering. The rims have a 50mm profile and are supported by 18 radially-laced spokes in the front wheel and 21 in the rear with doubling on the freehub side using Fulcrum's Two-to-One technology. 


  • Full carbon rim gives the wheel an extremely high level of lateral stiffness and greater reactivity
  • High Profile 50mm Carbon Tubular Rim for maximum aerodynamic penetration
  • Carbon Hub body gives the wheel a high degree of lateral stiffness and reduces weight
  • Oversized Flange on drive side increases torsional stiffness, increasing reactivity at each change in rhythm of the pedal stroke
  • Cup & Cone bearings for easy ball-bearing adjustment – reduces possible ball-bearing play – precision operation – maintains performance over time
  • Aluminium Axle reduces overall weight of the wheel
  • Quick Release Eccentric-closure system allows cyclist to modulate the pressure necessary for heightened sensitivity to find the proper closure for the block
  • Front: 18 aero spokes, radially laced in stainless steel with variable cross-section
  • Rear: 21 aero spokes in stainless steel with variable cross-section, doubled on the drive side (Two-to-One™)
  • Weight: 1325g per pair
  • Includes: Carbon Brake Pads
