Topeak Turboflow Valve Combo with Rapidhead

The Topeak Turboflow Valve Kit is an upgrade kit designed to solve the common headaches of tubeless setup: slow airflow and sealant-clogged valves. By replacing standard Presta cores and your pump’s head, Topeak claims an airflow increase of up to 300%, aiming to make seating stubborn tyres a breeze.

Design and installation

The kit consists of two high-flow valve cores and the ‘Rapidhead’ pump attachment. The cores are designed to fit any standard tubeless valve stem, while the Rapidhead is intended to replace your existing pump head.

To install the valve cores, you simply have to unscrew your old Presta valves using the included valve core removal tool, and then screw the Turboflow core onto the valve.

It’s worth noting that you will have to remove the new core before being able to take a valve in and out of the rim, as the diameter of the core is larger than a valve diameter.

A significant installation note: for my pump, I had to cut the hose to remove the old head. This left the hose slightly too short to reach the original storage clip on the pump body. Before you commit to the upgrade, check your hose length and diameter to ensure you won’t lose the ability to neatly stow your pump.

The Rapidhead experience

The Rapidhead eliminates the need for threading or flipping levers; you simply push the head onto the valve to seal it, pump to your desired pressure, and pull it off when finished. It’s an incredibly fast, ‘faff-free’ system that makes routine pressure checks much less of a chore.

In testing, the head performed flawlessly and importantly remains compatible with regular Presta valve cores. This means you aren’t “locked in” to the Turboflow system across all your bikes.

Performance and comparisons

The increased airflow is definitely noticeable when trying to seat a tubeless bead without a compressor. The wider internal bore of the Turboflow cores allows a massive volume of air to hit the tyre at once, which is exactly what you need for stubborn setups. Additionally, the larger opening seems less prone to being gummed up by dried sealant over time.

Sometimes though, you just need a massive amount of air at once to seat a stubborn bead, and this won’t supply you that, so you may still need an inflator of some type to help with stubborn large volume tyres. For most road situations though, I’ve found this combination to be adequate.

However, the valves aren’t perfect for every scenario. In my experience, they don’t play particularly well with screw-on mini pumps; I found that the valve cores would sometimes tighten or spin as I tried to thread the pump on.

Interestingly, the technology seems extremely similar to the Halo Hi-Flow Converter Valves I reviewed last year. Whether Topeak has licensed this tech or developed a very similar parallel, the performance characteristics are nearly identical.

Value

At just shy of £30, this is a significant investment for two valve cores and a pump head. Whether it is ‘worth it’ depends entirely on your setup. If you frequently swap tyres or struggle with a pump that has a finicky head, the Rapidhead alone is a fantastic quality-of-life upgrade. Liam seemed to see a lot of benefit in it when he tested it for off.road.cc, for example.

The Turboflow valve adaptors are also available for £19.99 without the Rapidhead.

The previously mentioned Halo versions come in at £14.99 for the pair, without the pump head, and performed exactly the same as the Topeak ones.

The Muc-Off Big Bore Valves allow for higher airflow than a regular Presta core and cost £40. They use a ball valve to allow for greater airflow, and Dave thought they were great, albeit pricey option.

Conclusion

If your current tubeless setup is working fine, the price might be hard to swallow. But if you’re dealing with constant sealant blockages or beads that refuse to seat, the Turboflow offers you a high-performance solution that genuinely works.
