AERO+ Optimised Carbon Endurance Road Rear Wheel

The DT Swiss ERC 1400 DiCut 45 Rear Wheel is a 700c carbon road wheel built for extended endurance riding across varied terrain. The ERC designation - Endurance Road Carbon - reflects a design philosophy that prioritises sustained performance, control, and comfort on longer routes rather than optimising purely for the shortest, flattest, most controlled race conditions. The 45mm rim depth sits in the mid-deep section range, balancing the aerodynamic gains of a deeper section with the crosswind stability and handling confidence that matters on the varied terrain and exposed routes that endurance riding regularly involves.

The AERO+ optimised rim profile is DT Swiss's designation for a rim shape developed specifically to deliver aerodynamic efficiency alongside comfort and handling control - the wider rim profile that the AERO+ designation implies accommodating wider tyres for the increased comfort and reduced rolling resistance that wider tyre setups provide on varied road surfaces. DT Swiss states that wider, more comfortable tyres can be used without compromising the wheel's aerodynamic character.

This listing is for the rear wheel only, in the 12x142mm thru-axle configuration with centerlock disc interface. The wheel is available with either an HG11 freehub body (for Shimano 11-speed and compatible systems) or an XDR freehub body (for SRAM 12-speed AXS cassettes). Confirm your drivetrain's freehub requirement before purchase as the two are not interchangeable. A disc rotor is not included.

• Fast and light Aero-optimized wheels for those longer rides on various terrains along your route. Ride comfortably and handle your bike safely even in fast descends
• 240 series Ratchet EXP 36 hub with SINC ceramic bearings
• T-head spokes are built with a 2-cross pattern

240 DICUT Aero Hub with Ratchet EXP 36 and SINC Ceramic Bearings

The rear hub is from DT Swiss's 240 series - the tier below the flagship 180, positioned as the high-performance production hub that balances weight, durability, and engagement quality for demanding road and endurance use. The 240 DICUT Aero hub uses the Ratchet EXP freehub system with 36 teeth of engagement - 36 points of contact between the drive ring and the ratchet, providing fast and positive power pickup when the rider resumes pedalling after coasting. The EXP designation indicates the Ratchet mechanism uses a spring-loaded design for reliable engagement across a range of temperatures and conditions.

SINC ceramic bearings are fitted as standard in this build - a bearing specification that uses ceramic ball material rather than steel for reduced rolling friction, improved durability under load, and longer service life compared to standard steel bearings. Ceramic bearings are a meaningful upgrade on a wheel intended for high-mileage endurance riding where bearing longevity and consistent rolling efficiency across extended distances are practical priorities.

T-Head Spokes in 2-Cross Pattern and Centerlock Disc Interface

The wheel is built with DT aero comp T-head spokes in a 2-cross lacing pattern. The T-head spoke profile is a blade-shaped design that reduces aerodynamic drag compared to standard round spokes while maintaining the structural properties needed for a reliable road wheel build. The 2-cross lacing pattern provides a balance of lateral stiffness and compliance suited to the endurance road wheel character of the ERC 1400 platform.

The centerlock disc interface requires a centerlock rotor for use - not a 6-bolt rotor. Confirm that your frame, caliper, and rotor are all centerlock compatible before purchase. The rotor is not included with the wheel.

FAQs

Is this a front or rear wheel?

This listing is for the rear wheel only in 12x142mm thru-axle with centerlock disc interface. The matching front wheel is available separately.

What freehub options are available for the ERC 1400 DiCut 45 rear wheel?

The wheel is available with an HG11 freehub body for Shimano 11-speed and compatible systems, or an XDR freehub body for SRAM 12-speed AXS cassettes. Confirm your drivetrain's requirement before purchase as the two are not interchangeable.

What hub does the ERC 1400 DiCut 45 use?

The rear wheel uses a DT Swiss 240 DICUT Aero hub with Ratchet EXP 36 teeth of engagement and SINC ceramic bearings.

What is the Ratchet EXP system?

Ratchet EXP is DT Swiss's spring-loaded freehub engagement mechanism. The 36-tooth version provides 36 points of engagement for fast and positive power pickup when pedalling is resumed after coasting.

What are SINC ceramic bearings?

SINC ceramic bearings use ceramic ball material rather than steel, providing reduced rolling friction, improved durability under load, and longer service life compared to standard steel bearings.

What is the rim depth of the ERC 1400 DiCut 45?

The rim depth is 45mm, placing it in the mid-deep section range for a balance of aerodynamic efficiency and crosswind stability on endurance routes.

Is a disc rotor included?

No. A centerlock disc rotor must be sourced separately. The centerlock interface requires a centerlock rotor - not a 6-bolt rotor.
