The Syncros Vernon 3.0TR is a mountain-bike specific track pump, with a claimed 665cc volume.
I found the pump to be very quick in inflating mountain bike tyres, requiring only 19 strokes to inflate a 29×2.4in tyre to 25psi.
However, it’s not as efficient as Topeak’s JoeBlow Tubi 2Stage, which managed it in 13 strokes.
Syncros Vernon 3.0TR pump spec and performance
The 3in analogue dial reads up to 60psi in 5psi increments, which makes it easier to read than standard track pumps when inflating to the lower tyre pressures you run with mountain bikes.
The head on the Vernon 3.0TR is only compatible with Presta valves, though the brand supplies a brass Schrader adaptor that can be stored on the baseplate.
The face of the head can be unscrewed and flipped to reveal an M6x0.8 fitting for seating tubeless tyres. I found the Vernon 3.0TR was able to seat a tubeless tyre without this.
The small head size proved useful when inflating smaller tyres, but this means there’s little stem insertion, which can make it difficult to tell if the head is seated.
Initially, the lever at the rear of the head was difficult to pull back. This loosened up after some use, but I found the snap closure unpredictable, often hitting my fingernail.
The handle of the Vernon 3.0TR is wide and flat, providing an efficient bar to transfer power. A hollow underside cheapens the feel slightly, though.
Considering the amount of plastic used in the construction, Syncros has made the connection between the plunger and cylinder very tight, which gives the pump a high-quality feel.
The 1,200mm hose extends up from the plastic trident stand, enabling easy attachment to valves regardless of whether your bike is stored on the floor or in a bike repair stand.
The pump’s base flexed under one-foot pumping, but was sturdy when used with two feet. However, the section of the base with the dial flexed when I pumped quickly.
Like many of the best track pumps, the hose loops over the handle to secure it and is held in place by two clips on the collar of the cylinder.
The clips on the Syncros hold the hose well, making it easy to detach when needed.
Syncros Vernon 3.0TR pump bottom line
Overall, the Vernon 3.0TR is a top performer that combines a high-quality plastic construction with great efficiency and ergonomics.
The only notable negative in testing was the way the base flexed when under duress.
