Wheel(s) DUKE SIERRA 42 - 32" / TUNE MICRO

From 1270 g* of versatility. Sierra 42 32-inch is an Elite gravel platform designed to maintain a high pace on fast tracks while gaining smoothness as the terrain becomes rougher.

The 42 mm depth supports speed, the 32-inch diameter reduces the angle of attack over obstacles, and the 28 mm internal width gives modern gravel tyres the volume they need to perform.

Key processes & technologies:

32-inch carbon architecture specifically recalibrated for the demands of the larger diameter.
28 mm internal width optimised for modern gravel tyres**.
SLR5: advanced Toray T1100 carbon-fibre lay-up and aerospace-grade resin.
SpokeCore: moulded spoke holes (24h) for a more homogeneous structure.
VFP: clearcoat-free finish, more durable and more environmentally friendly.
DRC: vibration filtering for more comfort and precision.
AntiPinch: anti-pinch rim edges to help reduce tyre cuts under impact.
2 mm Offset: asymmetric spoke bed to balance spoke tension and improve lateral stiffness and reliability.
Hooked / Tubeless Ready: safety and optimal compatibility with modern tyres

Result:

A 32-inch gravel wheel designed to carry speed, remain stable through rough sections and exploit the larger diameter without losing Sierra’s dynamic character.

* Weight +/- 30 g for a wheelset built with NonPlus CL SP hubs and Sapim CX-Ray spokes.

** Optimal tyre width: 40 mm <> 2.2”. Compatible tyre width: 36 mm <> 2.4”.

Technology

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
- Controls tire deformation for greater stability
- 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
Offset

OFFSET

Asymmetrical spoke lacing
- Balances spoke tension on both sides
- Improves lateral stiffness, stability, and long-term durability
- No added weight
AntiBurp

AntiBurp

Anti-burp and anti-debeading system
- Specially designed inner rim hooks lock the tire beads securely
- Eliminates air loss under heavy cornering or compression
- Prevents tire debeading, even in the event of a puncture
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.
