- Anti-Burp
The tyre bead is held in position regardless of pressure and driving conditions, so there is no risk of the tyre coming off the rim, even in hard cornering.
Two small ridges prevent the tyre from being pushed towards the inside of the rim, so you can't lose air on your supports!
- Anti-pinch
The sidewalls of the rim are thickened to prevent the tyres from cutting during impacts.

- Asymétrique (or offset)
Allows to increase the lateral rigidity of the wheel without taking weight. The rim holes are off-centre:
This allows the umbrella formed by the spokes to be closed more tightly. This way, the spokes provide better support for the rim and the lateral stiffness of the wheel is increased.
The risk of fogging is also reduced. Moreover, the asymmetry allows a better balance of the spoke 15% tensions between the two plies and thus guarantees a better durability of your wheel.

- C (Baccara 35C)
C for Clincher, tyre in French
- CL (DT240 CL)
CL for Center Lock (tightening of the disc by a single central nut)
- CRAZY (crazy jack, crazy star)
The "CRAZY" family of rims is designed for ALL MOUNTAIN use.
- Carbone 3K
3K carbon is a braided carbon with a "fibre pack" of 3000 filaments. The braiding is visible, small squares of 1mm by 1mm.
- Carbone UD
UD carbon is a unidirectional carbon. No visible pattern
- Design Hookless
The strength of the rim is superior to that of a carbon rim with hooks. This technology has been successfully used on our rims since 2011.
The height of the rim edges is deliberately reduced to limit the risk of contact with the ground and to avoid pinching the tyre.
- Disc brake
This says disc-braked rims
- Dynamal alloy
Dynamal aluminium is an aluminium alloy that is extremely resistant to fatigue, cracking and impact.
- E-Bike
Electrically assisted bicycle
- FURY (fury jack, fury star)
The "FURY" family of rims is intended for Enduro and DH use for the Fury Star HD.
- Jack (Lucky Jack)
The "Jack" indicates that it is a carbon rim! Example : Fury Jack, Crazy Jack, Mary Jack
- HD (Lucky Jack HD or Lucky star HD) Heavy Duty
The HD "Heavy Duty" construction makes it possible to cope with any terrain. The concept applies to all HD aluminium rims. It is based on a geometry optimised for mountain biking: asymmetrical rim, ultra-resistant alloys (Dynamal),
high shock and impact absorption capacity, specific spoking crossed by 2 and by 3.
- Wide rim
A wider tread pattern provides greater comfort for the same tyre cross-section due to the greater air volume in the tyre. The larger volume also improves performance and grip.
The stability of the bike in corners is also improved: a wider inner width reduces the rolling of the tyre under the rim when leaning.
With a narrow rim, the tyre floats from one side of the rim to the other without holding. By using a wide rim, the floating phenomenon is minimised and the behaviour and control of the bike is improved.
- LUCKY (lucky jack, lucky star)
The "LUCKY" rim family is designed for XC, Trail and Gravel Bike.
- MS (micro spline)
Shimano MTB 12-speed cassette mounting system with micro-spline.
- Offset (asymétrie)
Allows to increase the lateral rigidity of the wheel without taking weight. The rim holes are off-centre:
This allows the umbrella formed by the spokes to be closed more tightly. This way, the spokes provide better support for the rim and the lateral stiffness of the wheel is increased.
The risk of fogging is also reduced. Moreover, the asymmetry allows a better balance of the spoke tensions between the two plies and thus guarantees a better durability of your wheel.
- Paintless
Bare carbon finish, no varnish
- Directional drilling
Drilling a rim in the right direction will help to position the wheel nipples in perfect alignment with the spokes. This prevents spoke fatigue and therefore spoke breakage.
- System Max weight
This is the maximum weight (rider and equipment, fully equipped bike) supported by the wheels.
- Profil original by DUKE
DUKE owns the manufacturing tools for its aluminium rims and owns the moulds for the carbon models.
This allows us to offer state of the art rims with a modern, asymmetrical, wide profile, resulting from more than 10 years of experience.
- Ratchet
Toothed wheel or ring gear. The freewheel is driven by two interlocking toothed wheels.

- Rim Brake
This says wheels with rim brake pads
- Série R gravel
R for RACING, the R rims (World Runner Carbon 27R) are pruned compared to the same model without the R (World Runner Carbon 27)
- 6Ters* (sisters)
The Duke 6TERS* concept features a wider front rim than the rear for more grip, comfort and stiffness. Its weight is optimised for the necessary robustness.
The rear profile has been reworked by reducing its cross-section and modifying the lay-up of the carbon fibres to improve comfort and increase impact resistance,
The stresses are much greater at the rear than at the front. *6TERS = sisters.


- SLS2 Super light series 2
The SLS2 series is 15% lighter and stronger than the sls version, while maintaining exactly the same rigidity. The manufacturing process, the type of carbon fibre and resin are different.
In addition to these improved features, the SLS2 is manufactured in a sealed atmosphere and does not require any post-moulding. No sanding or varnishing, the finish is exceptional!
- SLS3 Super Light Serie 3
The SLS3 series is 10% lighter and stronger than the sls2 version, while maintaining exactly the same rigidity. The manufacturing process, the resin is different.
In addition to these improved features, the SLS3 is also manufactured in a sealed atmosphere and does not require any post-moulding. No sanding or varnishing, the finish is exceptional!
- SP (DT180 SP)
Straight Pull, the spoke does not have a bend at the exit of the hub bore, it comes out straight.
- Star (Lucky Star)
The "Star" indicates that it is an aluminium rim! Example : Fury Star, Crazy Star, Mary Star
- T (Baccara 35T)
Tubular in englisn. Tubular compatible wheel or rim.
- TLR
Tubeless ready, tubeless compatible wheel or rim.
- Tubeless
Tubeless compatible wheel or rim
- ULTRA
For ultra light, for the lightest DUKE rims, Lucky Jack Ultra, Lucky Star Ultra, Baccara Ultra for example.
- UV-shape
Corresponds to the V-shape of the latest generation of DUKE BACCARA road wheels.
- VAE
Electrically assisted bicycle
