DUKE RIM LUCKY STAR ULTRA 28
DUKE RIMS LUCKY STAR Ultra 28 Aluminium, versatile made for XC and Gravel bike
The Lucky Star Ultra 28 is a lightweight pure XC aluminium rim. It is characterised by its unrivalled stiffness/weight and strength/weight ratios, thanks in part to the use of Dynamal aluminium.
DUKE has created an innovative profile, following its own experience with a very strict specification.This rim inaugurates a new modern geometry with an asymmetric profile and hookless walls.The rim holes are off-centre (offset), which makes it possible to close the spoke umbrella more tightly. This rim is more stable and increases the lateral stiffness of the wheel.The spoke tensions between the two plies are more balanced, which guarantees a better durability of the wheel.The hookless rim walls allow for both rim reinforcement and weight reduction.
DUKE owns its manufacturing tools.
Technology
-
Tubeless
Our Tubeless compatible rims (UST, Tubeless Ready and Notubes), only require some Duke rim tape and a Tubeless-ready valve. They can also be used in a classic clincher set up (tyre & inner tube).
-
Dynamal
Dynamal is 50% stronger than 6061-T6. Unlike standard alloy blends, Dynamal is a pure alloy, enriched with magnesium-silicon and combined with a confidential metal to harden it. Compared with traditional alloys, Dynamal offers a significant increase in stress and impact resistance, without any reduction in fatigue strength.
-
Polyaxial-drilling
The orientation of the holes of a rim allows a perfect alignment of the nipples and spokes, which brings a better lifetime of the spokes, the rim and the wheel.
