Wheels DUKE Strada Æra 78-100 / Sram XDR

1,599 g* built to cut through the air. Strada Æra 78 / 100 is our most radical Elite carbon road wheelset for time trial and triathlon.

Its deep profiles are designed around sustained speed, beneficial inertia and rock-solid tracking when every second matters.

This Ready to Ride build features premium DUKE MadMax3 SP hubs, a differentiated SAPIM CX-Ray front / CX-Sprint rear spoke setup and a SRAM XDR freehub body (also available with Shimano HG11).

Key technologies & features:

24 mm internal width, optimised for 28 mm tyres**
Æra CFD profile: signature micro-profile surface reducing drag by up to 10% versus a smooth rim, without sacrificing crosswind stability
SLR5: refined Toray T1100 carbon lay-up with aerospace-grade resin
SpokeMold: moulded spoke holes for a more homogeneous structure
VFP: lacquer-free finish for greater durability and a lower environmental impact
DRC: vibration filtering for improved comfort and precision
Hooked / Tubeless Ready: secure, modern tyre compatibility

Result:
An extreme-aero wheelset designed to turn watts into speed in time trial and long-distance triathlon.

* Weight ±30 g.
** Compatible with tyres 28 mm wide and above.

Technology

Oriented-drillings

AERA (Airflow optimization by CFD*)

- Signature aerodynamic micro-profile
- Disrupts airflow and reduces turbulence
- No deterioration in stability in crosswind conditions
* Computational fluid dynamics
SLR5 (Super Light Road series 5)

SLR5 (Super Light Road series 5)
Exclusive manufacturing process combining optimized carbon fiber layup and aerospace-grade resin
- On average 20% lighter than the SLR2 generation
- Increased resistance to lateral stresses and vertical impacts
- Better vibration filtering for increased comfort and control
Hooked

Hooked

Hooked rim design
- Optimized for road and gravel tire pressures
- Ensures secure bead retention
- Wider internal width offers aerodynamic benefits
DRC (Dynamic Response Comfort)

DRC (Dynamic Response Comfort)

Controlled vertical flex and rebound
- More dynamic handling during weight transfers and bermed corners
- Increased comfort on rough terrain
- Reduced energy loss, more speed and efficiency
SpokeCore

SpokeCore

Molded spoke holes that eliminate the need for drilling
- Preserves carbon fiber integrity
- Reinforces the structure
- Allows for precise control of vertical and lateral stiffness
- Reduced weight and increased reliability
Width

Optimized Internal Width

Maximizes tire volume and performance
- Enables lower pressures without sacrificing rolling efficiency

- Improves control and comfort on all terrains
VFP (Varnish Free Process)

VFP (Varnish Free Process)

A varnish-free finish process
- Reduces VOC emissions and carbon dust during production
- More scratch-resistant surface
- Naturally glossy finish
Tubeless Ready

Tubeless Ready

Tubeless-compatible rim design
- Compatible with UST and Tubeless Ready standards
- Also compatible with tube-type (clincher) setups

Sapim Spokes

Sapim is THE go-to spoke brand, manufactured in Belgium since 1918. Several spoke models are available, depending on compatibility with your riding style and chosen rim:

Sapim CX-Ray: flat spoke, very light, durable, aerodynamic, and offers a very dynamic ride feel (309g / 64 pcs / 292mm)
Sapim CX-Sprint: flat spoke similar to the CX-Ray but thicker for even more stiffness (373g / 64 pcs / 292mm)
Sapim D-Light: round spoke, light and durable, with a central section diameter of 1.65mm, good value for money (344g / 64 pcs / 292mm)
Sapim Race: round spoke, strong and stiff with a central section diameter of 1.8mm (408g / 64 pcs / 292mm)

Nipples

Aluminum nipples with locking thread, available in 16 colors: black, red, silver, metallic grey, blue, aqua blue, gold, light gold, dark green, mint syrup green, lime green, lilac, pink, fuchsia pink, orange, and oil slick.
