Blackburn Core Pump

This pump is specifically optimized for high-volume mountain bike tires. While it will technically inflate a road tire, its larger barrel diameter is designed to move a lot of air quickly at lower pressures, rather than reaching the very high pressures required for skinny road tires.

The pull-out hose allows you to pump with more freedom of movement, which significantly reduces the stress placed on your valve stem. This design helps prevent the common issue of snapping or bending a valve stem while you are frantically trying to inflate a tire on the trail.

The pump head features a built-in slot designed to fit over a Presta valve core. Before you attach the pump, you can use this tool to ensure the core is tightened securely, which prevents air leakage and ensures the valve doesn't unscrew accidentally when you remove the pump head.

No, this specific model is designed exclusively for Presta valves. If you ride a bike with Schrader valves, you will need a different pump or a valve adapter.

Yes, the thread-on head creates a very reliable, airtight seal that won't pop off while you are pumping. It is a more secure connection than a standard press-on head, though it does take a few extra seconds to screw on and off.
