Know your mini-pump

-

DUAL/SMART HEAD

There are currently two valves in common use – Presta and Schrader. To work with both valves, some mini-pumps use an insert that you flip over inside the head, but the best come with smart heads that automatica­lly adjust without having to take anything apart. That said, as most mtbs use Presta valves, you only need to do it once. Both solutions work, but you usually pay slightly more for the latter.
