Big Bore Hybrid Tubeless Valves Iridescent 35mm - High Flow

In this review the Big Bore Hybrid Tubeless Valves are assessed for riders who value fast, reliable tubeless inflation and simplified sealant setup. The standout reason to consider these valves is their full bore, no core internal design that delivers substantially higher airflow and removes the need to remove a valve core during sealant filling. For anyone who regularly sets up tubeless MTB, gravel or road tyres and wants quicker seating and less fiddling, these valves offer a clear practical advantage.

Key Features

• Straight through internal design: The full bore pathway maximises airflow for faster inflation and easier seating of tubeless tyres.
• Hybrid ball valve system: The integrated mechanism allows for quick sealant filling without removing a valve core, saving time and mess during setup.
• Shrader fitment compatibility: Designed to work with Shrader pump heads so users can expect up to 254% increased airflow compared with standard Presta valves when using compatible pumps.
• Precision engineered dust caps: The iridescent caps protect the valve and provide a durable, visually striking finish that resists wear on trail or road.
• Multiple sizes and bases included: A selection of rubber bases and sizes helps ensure a secure fit across a variety of rim depths and profiles.

Who It's For

The Big Bore Hybrid is aimed at cyclists who regularly run tubeless tyres and want a faster, less fiddly setup process-especially riders who use floor pumps or compressors compatible with Shrader fittings. It suits mountain bikers, gravel riders and road cyclists who prioritise quick inflation and efficient sealant distribution.

Those who should look elsewhere include riders who must use only Presta pump heads without an adapter and riders who prefer a traditional valve core for compatibility with specialised inflators. Also, anyone needing an ultra-low-profile valve extender or very specific thread standards should confirm fitment with their rim first.

Pros & Cons

Pros

• Significantly higher airflow speeds up tyre seating and reduces time spent on tubeless setup.
• Easy sealant filling thanks to the integrated ball valve, avoiding core removal and mess.
• Solid build quality and attractive iridescent dust caps add durability and style.

Cons

• Best performance requires compatibility with Shrader pump heads, so some users may need adapters.

Frequently Asked Questions

Will these valves work with my floor pump?
They work best with pumps that accept Shrader fittings; users with Presta-only pumps may need an adapter to realise the full airflow benefit.

Do I need to remove the valve core to add sealant?
No - the integrated ball valve and straight through design let you fill sealant without removing a core, simplifying the process.

Is the 35mm length suitable for deeper rims?
The 35mm length fits many rims, and the product range includes multiple sizes plus rubber bases to help achieve the correct fit for different rim depths.
