Bike Shock Pumps


A shock pump is a type of bike pump that can deliver high pressure with low volume, which is ideal for fine-tuning your suspension performance. Read on for an overview of bicycle shock pumps and how to use them.

What is a bicycle shock pump?

A bicycle shock pump is a small hand-held pump that can attach to the air valves on your suspension components and inflate them with precise amounts of air. Unlike regular bike pumps that are designed for tyres, shock pumps can reach up to 300 psi (pounds per square inch) without much effort. Shock pumps also have gauges that show you how much pressure you are putting into your suspension, and some have digital displays for more accuracy.

Why do you need a bicycle shock pump?

You need a bicycle shock pump to adjust your suspension settings according to your riding style, weight and terrain. Suspension forks and shocks have two main parameters that affect their performance: sag and rebound. Sag is the amount of compression that occurs when you sit on your bike, and it should be around 20-30% of the total travel (the distance that your suspension can move up and down). Rebound is the speed at which your suspension returns to its original position after being compressed, and it should be neither too fast nor too slow.

To achieve the optimal sag and rebound settings, you need to inflate or deflate your suspension with a shock pump until you find the right balance. This will make your ride more comfortable, efficient and responsive. You should also check your suspension pressure regularly, as it can change due to temperature fluctuations or air leaks.

How do you use a bicycle shock pump?

To use a bicycle shock pump, follow these steps:

1) Locate the air valve on your fork or shock. It may be covered by a cap or dust cover that you must remove first.

2) Attach the hose of your shock pump to the valve. Make sure it is securely connected, and there is no air escaping.

3) Pump up or release air from your suspension using the handle or button on your shock pump. Watch the gauge or display to see how much pressure you add or remove.

4) Detach the hose from the valve carefully. Some air may escape during this process, so don't worry if you hear a hissing sound.

5) Repeat steps 1-4 for the other fork leg or rear shock if needed.

6) Test ride your bike and feel how it handles. You may need to make some adjustments until you find your preferred settings.

What are some of the best bicycle shock pumps?

  • Lezyne Shock Drive Pump: This compact and lightweight shock pump has an ergonomic handle and an aluminium barrel for durability. It has an integrated gauge that shows both psi and bar units and a zero-loss chuck design that prevents air loss when disconnecting from valves.

  • RockShox High Pressure: This professional-grade shock pump has a digital gauge that shows accurate readings up to 300 psi in 0.5 psi increments. It has an auto-shutoff feature that saves battery life and an anti-leak coupler that ensures minimal air loss.

  • Pro Bike Tool Shock Pump: This affordable yet reliable shock pump has an industrial-grade steel barrel and piston for strength and stability. It has an oversized gauge that shows both psi and bar units clearly and a flexible hose that rotates 360 degrees for easy access.

  • Topeak PocketShock DXG XL Shock Pump: This versatile shock pump can also be used for tyres thanks to its dual-function valve head that fits both Presta (narrow)and Schrader (wide) valves. It has an extra-long barrel for high-volume inflation and an analogue gauge
