Syncros has redesigned its digital shock pump, making it smaller and lighter. The pump is easy to use and small enough to carry in a backpack. This is a fuss-free, precise shock pump. Plus, it is easy to use and good value.

Syncros Boundary 1.0SH – Technical specification

This digital shock pump has a max pressure of 300PSI (20 bar) and measures in PSI, BAR or Kg/CM2. With 1 PSI/0.1 Bar measurement increments you can easily fine-tune your suspension pressures.

The screen is angled to improve visibility during use. It also has a handy cover to protect it when not in use. All this comes in a small package. It’s just 200mm in length which is easy enough to pack away or to keep stowed in the car or toolbox.

Syncros Boundary 1.0SH – Performance

I’ve tested this pump on a variety of forks including Fox 38/36, Rockshox Lyrik, and Pike as well as rear shocks like the Fox Float X/X2 and RockShox Super Deluxe. The different interfaces proved to be no issue for the pump, all read and adjusted air pressure as expected.

The air bleed turn valve is arguably easier to fine-tune than the usual button release, but it does require a little finesse when making small adjustments.

The pump action is smooth and the large pad on the end fits into the palm nicely. The chamfered edge creates a comfortable platform to push against when pumping, even at max pressure.

Changing the battery is straightforward enough but does require a little patience. Four fiddly 1.5mm Allen key bolts remove the casing, and a flat blade screwdriver releases the battery.

Syncros Boundary 1.0SH – Value and verdict

At £68, the Syncros Boundary 1.0SH digital shock pump stands up against the competition as good value. The Topeak Pocketshock comes in at £75, but Liam found some problems with its performance. The Lifeline Digital shock pump is worth looking at as well, it comes in cheaper at £45, but it is larger, so would arguably be tougher to stow away if that’s a requirement.

If you’re after a quality digital shock pump that is easy to use, has a clear display, and can be easily stowed away in a bag whilst riding, the Syncros Boundary 1.0SH is a solid contender. The battery is a little fiddly to change and you’ll need to possess some finesse whilst operating the air adjust valve, but these are very picky downsides to what is an excellent shock pump.
