Syncros is part of Scott Sports, and its Vernon 2.0HV (High Volume) is a mountain bike-specific track pump with a limit of 40psi.
Each stroke pushes a fair bit of air through its hose, so pumping up larger volume mountain bike tyres requires relatively few strokes to get up to pressure, and popping a tubeless tyre into the rim’s bead is easy.
However, with plenty of air being pushed through, the stroke isn’t the easiest, so you’ll have to push fairly hard on the handle when pressures get towards its maximum of 40psi.
Unfortunately, the handle itself isn’t the most comfortable out there, with just a simple, straight plastic construction, and little in the way of ergonomic design.
The structure of the pump, with a steel barrel and reasonably wide feet, is solid in action and there’s minimal flex or wobble. The hose is nice and long, which is ideal for inflating tyres on bikes held in a workstand or hiding round the corner as you pump up a tubeless tyre on a baggy rim!
During the stroke, I felt the needle jumped around a fair bit, which was off putting, but the gauge is located at the top of the barrel for easy reading and, with a 40psi limit, it’s clear where the needle is pointing once it settles down.
There’s a bleed valve located next to the gauge to help get pressures right, and I found the gauge to be accurate.
The pump head has a simple flip-lock design, with a swappable head between Presta and Schraeder, which proved to be solid and secure in testing.
Unfortunately, the clip into which you can store the pump head feels a touch oversized, so the head is prone to falling out – a small niggle.
How we tested
This pump was tested as part of a grouptest of six track pumps to find out which home-workshop tyre inflator is the best and worth your hard-earned cash.

- Birzman Maha Grand Push & Twist III
- Lezyne Classic Over Drive
- SKS Air-X-Press 8.0
- Topeak Joeblow Mountain X
- Park Tool Home Mechanic Floor Pump PFP-8
