The DT Swiss ARC 1100 DICUT 38mm Carbon Spoke Rear Wheel WTS pairs a 38mm deep toroidal carbon rim with carbon fibre spokes, 240 DICUT hub, and Ratchet EXP engagement. The carbon spoke construction reduces both rotating weight and aerodynamic drag from the spokes — delivering a rear wheel that is fast uphill and on the flats, with the WTS kit for complete ownership support.

• 38mm deep toroidal DICUT carbon rim — lightweight aero profile for climbing and versatile road racing
• Carbon spokes — lighter and more aerodynamic than bladed metal spokes
• 240 DICUT hub with Ratchet EXP 36-point star ratchet
• Tubeless-ready clincher construction
• WTS (Wheel Tuning System) spare parts kit included
• Freehub options: Shimano HG, SRAM XD, Campagnolo

Carbon spokes on the rear

Carbon fibre spokes deliver a measurable weight saving and aerodynamic improvement over conventional bladed alloy spokes. On a 38mm rim where rotating mass directly affects climbing performance, every gram saved at the rim and spoke matters. Carbon spokes also contribute to a stiffer, more direct power transfer feel.

38mm depth for climbing and mixed racing

The 38mm toroidal profile excels where weight and crosswind handling matter — mountain road stages, mixed gran fondo courses, and criteriums with punchy accelerations. It rolls fast and handles predictably in conditions where deeper sections become a liability.

240 DICUT hub and Ratchet EXP

Ratchet EXP 36-point engagement, externally serviceable, freehub-swappable between Shimano HG, SRAM XD, and Campagnolo.

WTS — Wheel Tuning System

Valve stems, rim tape, spare nipples, and Ratchet EXP service components included.

Compatibility

Rim brake road bikes (clincher). Tubeless or clincher tyre compatible. Freehub: Shimano HG, SRAM XD, or Campagnolo — specify at purchase. Note: use care during tyre mounting to avoid contacting carbon spoke heads with tyre levers.
