Product Information
Full details
The Topeak Pocket Rocket DX II is designed for road cyclists prioritizing performance and comfort on long rides. Its key benefit is the ability to inflate tires to a high 160 psi with a comfortable grip, ensuring you can quickly get back on the road after a puncture. A potential caveat is its pocket-sized nature, which might require more effort for very low-pressure tires or for users preferring a larger pump.

FAQs
What type of valve does the Topeak Pocket Rocket DX II work with?
This pump is designed for Presta valves. While it might fit Schrader valves, it is optimized for the higher pressures typically used with Presta valves.
How much does the pump weigh?
The Topeak Pocket Rocket DX II weighs approximately 4.05 oz (115g).
What is the maximum pressure it can inflate to?
It can inflate tires up to 160 psi (11 bar).
Can I mount this pump on my bike?
Yes, it includes a side mount bracket that can be attached to your bottle cage bosses.
Is it suitable for mountain bike tires?
While it can inflate mountain bike tires, it's best suited for the higher pressures of road bike tires. For lower pressures and larger volumes typical of mountain bikes, a larger pump might be more efficient.
How long is the pump when extended?
The pump measures 8.7 inches (22 cm) in length.
What is the handle made of?
The handle is made of a dual-density polymer for improved grip and comfort.
Troubleshooting
Pump not inflating tire
Ensure the pump head is securely and properly attached to the Presta valve. Check that the valve itself is open (unscrew the valve tip). Verify the pump's internal mechanism is functioning by pumping in the air.
Air leaking from pump head
Inspect the rubber seal within the pump head for damage or debris. Ensure the thumb lock is fully engaged. If the seal is worn, it may need replacement (contact Topeak for parts if available).
Handle feels stiff or difficult to move
The internal seals may need lubrication. Apply a small amount of silicone-based lubricant to the pump barrel and cycle the pump several times. Avoid petroleum-based lubricants.
Pump won't reach high pressure
Ensure the tire is not completely flat. Check for any obstructions in the pump barrel or head. For very low pressures, it may take more strokes than anticipated. Ensure the thumb lock is fully engaged.
Pros and Cons
Pros
- High inflation pressure (160 psi) suitable for road bikes.
- Durable and lightweight aluminum construction.
- Comfortable and secure Ergo-fit handle.
- Compact and portable design.
- Includes a convenient side mount bracket.
Cons
- May require more effort for very low tire pressures compared to larger pumps.

Setup, Compatibility & Care
Setup: The Pocket Rocket DX II typically comes ready to use. If mounting to your bike, utilize the included side mount bracket. Secure the bracket to your bottle cage bosses using standard water bottle bolts. Ensure the pump is firmly attached to the bracket. Before first use, it's advisable to briefly cycle the pump to ensure smooth operation.
Compatibility: This pump is designed primarily for Presta valves, common on road bikes, due to its high-pressure capability. It may not be the most efficient choice for Schrader valves found on mountain bikes or some hybrid bikes.
Care:
- Keep the pump head clean, especially the valve interface. Use the integrated dust cap when not in use.
- Periodically wipe down the aluminum barrel and handle with a slightly damp cloth.
- Avoid exposing the pump to extreme temperatures for prolonged periods.
- If the pump feels stiff, a tiny amount of silicone lubricant can be applied to the barrel seal, but this is rarely needed with regular use.
