Early Bird has launched the Serin RBA, their first rebuildable bridge designed specifically for boro tanks. It comes with multiple airflow pins to support both MTL and DTL vaping styles, with an optional Serin MTL kit available for those who prefer a tighter draw. As with other Early Bird rebuildables, extensive testing by experienced designers and vapers has helped ensure exceptional performance and quality.
Featuring a single-coil build deck and simple wicking with anti-leak technology, the Serin RBA can be paired with most premade boro coils to deliver impressive flavour. If you’re a fan of AIO or Boro mods, the Serin RBA is a great addition to your setup. The first release is available in two finishes — Matte Black and Stainless Steel — and includes a top-airflow system engineered to maximise flavour. Another high-quality, high-performing rebuildable from Early Bird.

Five Interchangeable Air Pins
The Serin RBA includes five airflow pins ranging from 1.5mm to 3.5mm, allowing you to fine-tune your draw to suit your preference. Opt for the 1.5mm pin for a tighter MTL inhale, or switch up to 3.5mm for a more open, restricted DTL experience. Easily change the pins to match your coil build, e-liquid, or vaping style — a level of airflow versatility not often found in boro bridges.
Single Coil Build Deck
Designed with simplicity in mind, the single-coil deck offers straightforward coil installation with plenty of working space. Wicking is equally hassle-free, and the anti-leak technology allows for slightly looser wicking without the concern of e-liquid seeping into your boro tank.
Top-Airflow System
Airflow enters from the top and is directed down toward the coil, helping to deliver clean, consistent flavour while reducing the risk of leaks. Top-airflow designs typically remain drier than bottom-airflow alternatives, making them an ideal choice for boro bridges.
Boro Tank Compatibility
The Serin RBA is compatible with most boro tanks and AIO devices that support boro bridges. Whether you’re looking to transition from stock coils to custom builds or prefer the convenience of premade boro coils, the Serin offers flexibility for a wide range of setups.
Why Choose the Serin RBA?
Marking Early Bird’s debut in the boro bridge category, the Serin RBA combines thoughtful design with reliable performance. With five airflow options covering everything from tight MTL to more open DTL draws, an easy-to-build single-coil deck, and a leak-resistant wicking system, it’s a strong choice for vapers seeking enhanced flavour and greater control over their experience.
