Topeak Joeblow Mountain X pump review

The Joeblow Mountain X is one of the highest volume track pumps out there, designed with mountain bike tyres specifically in mind.

The large volume means minimal strokes to get up to pressure, but conversely more air through the hoses means a tougher stroke.

Further to the rapid inflation benefits of the large volume is the ease at which tubeless tyres can be popped in to the rim. While the force required to complete a stroke of the pump is higher than many other track pumps, the larger volume of air makes tubeless inflation simple.

The metal construction is solid in use, though standing on the two stabilising feet at the base is required because front to back stability isn’t as good as some track pumps.

The handle has a rubberised finish, which is comfy to hold, but a slightly more swept-back handle shape would make it even more comfortable. Pushing the handle reveals a very smooth feeling stroke.

The head has a large locking lever and is double sided to work with both regular valve types.

Towards the base of the pump is a bleed valve to help regulate tyre pressures, and the gauge, mounted ¼ of the way up the barrel, is large and very easy to read.

It also comes with a movable marker, should you have a particular pressure in mind, making it even easier to hit your desired pressure. The gauge itself, proved reliable against my digital pressure gauges.

The hose clips in to the barrel for tidy storage, though I found that the hose wasn’t quite as long as I’d like, compromising the ability to inflate tyres of bikes held in a bike stand.
