Scope's R4 takes the rim shape of its award-winning Artech series and builds it into a 1349g, 45mm race wheelset for climbing, racing and everyday training. Wide hooked rims suit modern 28mm tyres.

Highlights

  • 45mm deep carbon rims with 23mm internal width, optimised for 28mm tyres
  • 1349g claimed set weight (without rim tape and valves)
  • 36T Diamond Ratchet SL rear engagement with titanium, DLC-coated ratchets
  • SKF bearings and a labyrinth seal to keep dirt out
  • Tubeless valves and tubeless rim tape pre-installed

Race Series technology

Scope's Race Series borrows the rim profiles of its Artech series, shaped by Scope's Algorithm Enhanced Aerodynamics (AEA) process, without the Artech's Aeroscales. Local Reinforcement adds carbon layers only around the spoke holes to save weight while keeping strength and stiffness, and the Scope Tubeless System is designed for easy mounting, direct inflation and long-lasting pressure.

R-Series hubs

The rear hub uses Scope's 36T Diamond Ratchet SL engagement: titanium, finished with a diamond-like carbon coating for direct engagement, durability and low weight. Both hubs run SKF bearings and a mechanical labyrinth seal that keeps dirt out for long-term reliability. Wheels are laced with Sapim CX-Ray spokes.

Compatibility & fit

Disc brake only, with Centerlock rotor mounts. Axles are 12 x 100mm thru-axle front and 12 x 142mm thru-axle rear. Choose a Shimano HG freehub body for Shimano road cassettes or SRAM XDR for SRAM XDR cassettes. The hooked rim is tubeless ready and compatible with tubeless and clincher tyres; Scope's optimum tyre width is 28mm. Wheel fitting, tyre installation and set-up are separate Tune Cycles workshop services and are not included.
