The DT Swiss ARC 1400 DICUT 85mm rear wheel is the depth choice for riders who want every available aerodynamic advantage at the rear of their disc brake road bike. With an 85mm DICUT carbon rim and Ratchet EXP engagement, this wheel is designed around one priority: speed on flat, fast terrain.

• 85mm DICUT carbon rim with toroidal aero profile
• Disc brake specific — 12x142mm rear axle standard
• Tubeless-ready clincher construction
• Ratchet EXP engagement system
• WTS (Wheel Tuning System) — rim and tyre matched for maximum aero performance
• 700C / 622mm bead seat diameter

The deepest ARC 1400 rear wheel

85mm of DICUT carbon at the rear delivers the strongest aerodynamic return in the ARC 1400 disc range. The toroidal rim profile reduces drag on the rear wheel — where aerodynamic benefit is most pronounced relative to weight penalty — across the yaw angles encountered in real racing conditions.

Disc-engineered rear end

Built around 12x142mm thru-axle standards, this rear wheel manages disc braking loads through a hub and spoke system designed specifically for disc brake force paths. Confirm freehub driver compatibility with your drivetrain before ordering.

Wheel Tuning System

WTS ensures the 85mm rim is paired with a tyre that has been validated to complete the aerodynamic package. A matched tyre is required to realise the full benefit of this depth.

Compatibility

Axle: 12x142mm rear thru-axle. Brake: disc (rotor not included). Tyre type: tubeless-ready clincher (tyre not included). Best suited for flat-to-rolling courses. Sold as individual rear wheel. Confirm freehub driver compatibility before ordering.
