Mountain mini pumps move more air per stroke than road pumps. There's nothing to stop you using a road-specific mini pump to pump a fat mountain tyre, but you'll be pumping for a long time. We've included Topeak's Mini Master Blasters as they're a dual action pump, making them suitable for both purposes. Check out the Topeak Morph pumps: a floow pump is easy to use, a mini pump is easy to carry. A Morph pump is a portable pump that works like a floor pump - great for people who have trouble pumping their tyres to the required pressure, or keeping the pump properly engaged on the valve.
