Dugast Small Bird Cotton Neoprene Coating Cyclo-cross Tubular Tyre

Hose Dugast Small Bird: performance and grip on slippery surfaces

The cyclo-cross inner tube Dugast Small Bird Cotton with Neoprene Coating is a top-of-the-range model designed for players looking for an excellent balance between performance, grip and control on cyclo-cross courses.

Reference 11A00664, this hose in the size 700 × 33 mm uses a carcass 240 TPI cotton particularly flexible and a tread pattern specially developed for mixed and slippery terrain, particularly on wet or dry grass courses.

The Small Bird profile stands out for its clever design: the side studs are taller than those in the centre to promote theskid when cornering, whilst the less aggressive centre section ensures good performance on fast-rolling sections.

Small Bird profile: the balance between performance and grip

The Small Bird holds a particularly interesting position in the range Dugast.

Its design has been developed for surfaces with a low level of grip, particularly on grassy fields and tracks. The central tread features relatively low studs to minimise rolling resistance on fast sections.

Conversely, the studs on the sides are taller. They provide greater grip when the bike is leaned into bends. This difference in height between the centre and the shoulders ensures a balanced handling between performance on straights and safety when cornering. .

The Small Bird is therefore particularly well suited to courses that alternate between long, fast-paced sections and bends on wet grass.

A 240 TPI cotton carcass for greater flexibility

The frame made of 240 TPI cotton is another of the Dugast Small Bird.

A flexible carcass allows the tyre to better conform to uneven terrain and ensures consistent contact with the ground. This feature is particularly useful in cyclo-cross, where courses may include grass, dirt, gravel, roots and small bumps.

The desired outcome is behaviour that is both comfortable, precise and high-performing, with a good ability to maintain grip when the tyre pressure is adjusted to suit the conditions.

The technical data sheet for item number 11A00664 states a core density of 240 TPI and a manufacturer’s weight of approximately 390 g. .

Neoprene Coating: protection designed for cyclo-cross

The Neoprene Coating provides additional protection for the cotton casing.

An app forAquasure manufactured directly at the factory provides better protection for the sidewalls against moisture and spray encountered during cyclo-cross rides. This feature is particularly useful when the tubular tyre is used regularly in autumn and winter, in wet and muddy conditions.

This protection helps to preserve the qualities of the cotton carcass whilst offering greater peace of mind when used in challenging conditions.

A width of 33 mm, ideal for cyclo-cross

The Dugast Small Bird is available in 700 × 33 mm, i.e. a dimension 33-622.

This section is an excellent compromise for cyclo-cross: it offers sufficient surface area to work on tyre pressure and find grip, whilst remaining suited to the demands of competition.

However, the actual width achieved may vary depending on the internal width and the profile of the rim.

Compatibility with modern wheel rims

The version Small Bird Cotton with Neoprene Coating 11A00664 is designed for tubular rims with an internal width ranging from up to 27 mm. .

This point is particularly interesting in light of developments in cyclo-cross wheels, whose rims have become wider in recent years.

Important: Always check the internal width of your rim before fitting to ensure it matches the tube’s specifications.

For which types of terrain should the Dugast Small Bird ?

The Small Bird is particularly effective when the course has a surface slippery but relatively easy to ride on.

It is particularly suitable for:

• grass course ;
• damp grass ;
• dry grass ;
• mixed-use sites ;
• gravel paths ;
• a slightly muddy route ;
• slippery surfaces ;
• circuits that alternate between fast sections and technical bends.

It is a particularly good choice when you’re looking for greater versatility than a highly specialised tyre designed for deep mud can offer.

Small Bird, Rhino or Typhoon: which one should you choose ?

The choice of profile depends mainly on the terrain.

Small Bird: Ideal for slippery surfaces, particularly grass, offering an excellent balance between performance and grip when cornering.

Typhoon: more geared towards versatility across different types of terrain and courses where performance remains a key factor.

Rhino: to be preferred when the ground becomes very wet and muddy and the priority is on traction and clearing away the mud.

The Small Bird therefore offers a balance between the performance of a fast profile and the grip of a more aggressive profile.

Expert advice: If your route consists mainly of grass with slippery bends and a few gravel sections, the Small Bird is a particularly good choice. If the mud becomes deep and sticky, you’re better off opting for a Rhino tyre.

Installation and maintenance

The Dugast Small Bird is a tubular hose. It must therefore be mounted on a tubular-compatible rim.

Assembly and gluing must be carried out with precision to ensure that the hose is positioned evenly and held securely, particularly when it is used in competition.

After a ride in muddy or wet conditions, gently clean the inner tube and then leave it to dry naturally. Avoid using harsh cleaning products that could damage the casing or the protective coating.
