Dugast Rhino Flying Doctor inner tube: the specialist for greasy and muddy terrain

The Rhino Flying Doctor Neoprene CoatingDugast is a top-of-the-range tyre specially designed for cyclo-cross on greasy, wet and muddy terrain. Reference 11A00663, it combines the renowned Rhino tread pattern with a Flying Doctor casing and Neoprene Coating sidewall protection.

Its high, widely spaced tread pattern provides excellent traction and grip in mud, whilst the open tread design facilitates the removal of dirt and debris. The result is a tubular tyre capable of maintaining grip when the course becomes particularly technical and challenging.

The Flying Doctor technology, meanwhile, allows the tubular to be used at low pressure whilst maintaining good stability – a major advantage in cyclo-cross where control and traction are paramount.

Rhino tread pattern: designed for mud

The Rhino is one of Dugast ’s most specialised tread patterns for challenging conditions.

Its particularly tall knobs provide grip on loose terrain. Their open pattern facilitates the removal of mud as the wheel turns, preventing the tread from becoming virtually smooth.

This design is particularly useful when the ground is waterlogged, deeply soft or worn down by successive riders.

The Rhino therefore clearly prioritises traction, grip and control over the pure performance of a tread pattern designed for dry conditions.

Flying Doctor: harnessing the benefits of low pressure

The Flying Doctor casing is an essential component of this tubular tyre.

It has been specifically developed to allow riding at very low pressure, whilst maintaining good tyre stability. This feature enables the cyclist to fine-tune their tyre pressure to suit the course conditions.

In cyclo-cross, lower pressure can provide greater contact between the tyre and the ground. This notably improves the bike’s ability to tackle technical sections, tree roots and muddy patches without losing too much traction.

The Flying Doctor casing is specified as 240 TPI across this range of tubular tyres Dugast.

Neopreen Coating: protection tailored to cyclo-cross

The Neopreen Coating treatment protects the tyre’s sidewalls thanks to afactory-applied layer ofAquasure.

This protection notably limits water ingress into the casing and improves its resistance to wet conditions. This is particularly relevant for a tubular tyre intended for use in mud, water and repeated splashes.

The coating therefore allows you to enjoy the flexibility of the cotton casing with greater peace of mind, whilst improving its protection against winter cyclo-cross conditions.

A tubular tyre designed for the toughest conditions

The Rhino Dugast stands out from more versatile tyres such as the Typhoon due to its much stronger focus on soft, muddy terrain.

It is particularly well-suited when the course features:

• deep mud;
• very soft ground;
• soggy grass;
• technical sections;
• slippery slopes;
• loose ground;
• areas where traction is crucial.

Its open tread pattern allows mud to be effectively shed, whilst its tall lugs provide the necessary grip when the ground is soft.

Expert tip: don’t necessarily aim for the lowest possible tyre pressure. The best setting depends on the rider’s weight, the rim, the terrain and riding style. Start gradually and then lower the pressure until you achieve the best balance between grip, stability and rim protection.

For a dry, fast route, however, we’d opt for a more rolling tread pattern such as the Typhoon or the Pipistrello. For a very muddy race, the Rhino really comes into its own.

Rhino or Typhoon: which one to choose?

The choice depends mainly on the terrain.

Rhino: best for soft, loose and muddy terrain, when traction and mud clearance are priorities.

Typhoon: more versatile, it’s better suited to routes alternating between fast sections, grass, dirt and variable conditions. The Typhoon Flying Doctor is specifically designed for use on all types of terrain.

In summary: the muddier the route, the more appealing the Rhino becomes.

Fitting and maintenance

The Rhino Flying Doctor Dugast is a tubular tyre and therefore requires a rim specifically designed to accommodate this type of tyre.

Fitting must be carried out with care to ensure the tyre is positioned perfectly evenly and sits securely on the rim. For competition use, professional gluing is strongly recommended.

After a muddy race, remove any mud residue and allow the tubular tyre to dry naturally. Even with the Neopreen Coating treatment, regular maintenance helps to preserve the casing and sidewalls.
