The Topeak JoeBlow Tubi 2Stage is built to solve two common workshop problems with one pump. Mountain bike and gravel tyres need a large volume of air delivered quickly, particularly when seating a tubeless bead, while road tyres need a pump capable of reaching much higher pressures. The JoeBlow Tubi 2Stage switches between those jobs using a simple selector on the barrel.

That versatility makes this review of the Topeak JoeBlow Tubi 2Stage especially relevant for riders who own more than one type of bike. It can quickly inflate a high-volume MTB or eMTB tyre, handle gravel rubber and then switch into a high-pressure setting for a road bike. More importantly, its TubiHead can remove and reinstall a Presta valve core while remaining connected to the valve.

In use, the pump felt solid, stable and impressively quick. The sturdy steel base gives you confidence to pump hard, while the oversized handle is comfortable enough for repeated use. The valve-core tool also makes tubeless setup much cleaner and simpler, particularly when adding sealant or trying to push enough air through the valve to seat a stubborn tyre.

If you are setting up new rubber, our eMTB tyre pressure guide explains how to find a sensible starting pressure once the bead is seated.

Topeak JoeBlow Tubi 2Stage: Review

Solid, stable and easy to use

The first thing you notice about the JoeBlow Tubi 2Stage is how substantial it feels. The steel base is wide and sturdy, keeping the pump planted even when you are trying to move air quickly into a large-volume mountain bike tyre.

There is little flex through the barrel or base, and the large padded handle gives enough room to use both hands comfortably. That stability is important during tubeless setup because seating a bead often requires faster, more committed strokes than simply topping up a tyre before a ride.

The two-stage selector is positioned at the top of the barrel and is simple to operate. Stage 1 opens both chambers to deliver maximum volume, while Stage 2 uses the smaller chamber for higher pressures. The switch has a positive action, so it is immediately clear which setting you are using.

For normal MTB and eMTB pressures, Stage 1 does most of the work. The pump moves a substantial amount of air with each stroke and makes inflating wide tyres noticeably quicker than with a conventional high-pressure track pump.

Tubeless setup and the TubiHead

The TubiHead is the feature that separates this pump from a normal two-stage floor pump. It connects to a Presta valve and allows the valve core to be removed while the pump remains attached.

Removing the core creates a much larger opening for air to pass through. That makes it easier to deliver the rapid airflow needed to push the tyre beads onto the rim shoulders. Once the tyre is seated, the core can be screwed back into place before the pump is removed, reducing the amount of pressure lost during the process.

It is a particularly useful system when working with sealant. The valve core can be removed for adding sealant, before the pump is connected and used to inflate the tyre. Because the core is reinstalled before the head comes away, there is less opportunity for air and sealant to escape together.

The mechanism was easy to use in testing, although some riders may need a couple of attempts to understand how the core-removal control works. Sealant should also be wiped away before it dries inside the head.

Fast inflation for MTB and eMTB tyres

Speed is one of the JoeBlow Tubi 2Stage’s biggest strengths. Stage 1 delivers a claimed 715cc of air with each stroke, making short work of high-volume MTB, eMTB and gravel tyres.

That is useful for more than initial tubeless installation. Electric mountain bike tyres should be checked regularly because a few PSI can noticeably change grip, casing support and rim protection. The pump makes those routine pressure checks less of a chore, particularly if you are running wide 2.4in or 2.6in tyres.

The large gauge separates the lower and higher pressure ranges, making the MTB section easier to read than a conventional 160psi gauge with tightly packed markings. There is also a movable reference marker, so you can mark your preferred pressure and return to it more consistently.

The pressure-release button on the head is another useful detail. If you slightly overinflate a tyre, you can bleed air in small amounts rather than disconnecting the pump and pressing the valve manually.

Gravel and road versatility

The JoeBlow Tubi 2Stage is not limited to mountain bike tyres. Stage 1 works well for wide gravel tyres, while Stage 2 allows the pump to reach the much higher pressures used by narrower road setups.

Once the pressure reaches around 30psi, switching to the smaller chamber reduces the effort needed to keep increasing it. Topeak claims a maximum of 160psi, which is far beyond what most modern road riders will require, but it demonstrates the range available.

That makes the JoeBlow a strong workshop option for households with several bikes. A conventional high-volume MTB pump can become difficult at road pressures, while a narrow-barrel road pump takes too long to inflate an eMTB tyre. The two-stage design avoids having to keep separate floor pumps for each bike.

It is also more convenient than storing a separate tubeless air tank, although dedicated charged-chamber pumps can deliver a more explosive initial blast for particularly stubborn tyre and rim combinations.

What is not so good?

The main drawback is the hose length. It is adequate when the bike is standing on the ground, but it can feel restrictive if the bike is held high in a workshop stand. A longer hose would make it easier to reach valves without moving the pump or rotating the wheel.

The TubiHead also takes slightly more technique than a basic locking pump head. Although I found it straightforward, other users may need time to become familiar with removing the valve core and releasing the head cleanly. Pulling too aggressively can make it harder than necessary.

Sealant is the final maintenance consideration. The system is designed to reduce mess, but wet sealant can still reach the pump head during tubeless work. Wiping the head and valve tool after use will help prevent dried sealant from affecting the mechanism.

These are relatively minor complaints. The underlying pump remains fast, stable and highly effective across a wide range of tyres.

Final verdict

The Topeak JoeBlow Tubi 2Stage is an excellent workshop pump for riders using tubeless MTB, eMTB or gravel tyres. The sturdy steel base gives it a stable platform, the high-volume setting inflates wide tyres quickly and the TubiHead makes removing the valve core far easier than using a separate tool.

Its real strength is versatility. Stage 1 deals with high-volume tyres, Stage 2 reaches road-bike pressures, and the integrated valve-core system removes much of the frustration from tubeless installation. It is also quick and simple enough to use for routine pressure checks before every ride.

The hose could be longer, and the TubiHead should be kept clear of dried sealant, but neither issue undermines the overall performance. For riders who regularly fit tubeless tyres and want one pump for MTB, gravel and road bikes, the JoeBlow Tubi 2Stage is a very capable and well-built option.

Topeak JoeBlow Tubi 2Stage FAQs

Can the Topeak JoeBlow Tubi 2Stage seat tubeless MTB tyres?

Yes. The pump’s high-volume mode and removable valve-core system deliver enough airflow to seat many tubeless MTB, eMTB and gravel tyres without a compressor or separate pressure chamber.

How does the TubiHead valve-core tool work?

The TubiHead connects to a Presta valve and uses an integrated control to unscrew the valve core while the head remains attached. The tyre can then be inflated through the open valve before the core is reinstalled.

Can the JoeBlow Tubi 2Stage be used with road tyres?

Yes. Stage 2 uses the smaller pump chamber to reach pressures up to 160psi, making the pump suitable for road tyres as well as gravel, MTB and eMTB tyres.

Does it work with Schrader valves?

Yes. The TubiHead is primarily designed around Presta valves, but a Schrader adaptor is included. The integrated valve-core removal function is for two-piece Presta valve cores.

Is a charged-chamber pump better for tubeless tyres?

A charged chamber can deliver a stronger single blast of air and may be better for very stubborn tyres. The JoeBlow Tubi 2Stage avoids charging a separate tank and works extremely well when the valve core is removed, while also functioning as a versatile everyday floor pump.
