Both high pressure and high volume
Why buy a high pressure or high volume pump when you could have both? The high volume setting is great for MTB and larger gravel tires, and the high pressure setting is ideal for road tires.
Presta & Schrader valve compatible
When connecting the pump to your Schrader or Presta valve, simply press down and the pump head will auto-select to the correct valve to pump up all of your tires.
Large base, large gauge
The large, stable base of the Dual Charger keeps the pump upright with huge gauge to see every PSI and Bar marking to the max PSI of 160 and dial in the exact pressure you need.
Durable steel construction & serviceable
The steel base and body mean that the Dual Charger will stand up to everyday use. If something does happen, we have replaceable internals to extend its life.
Hidden accessories
Hidden inside the pump handle, we included 2 recreation ball accessories to keep your floaties and soccer ball inflated.
30-Day Unconditional Guarantee
If for any reason you're not satisfied with a Bontrager or Trek aftermarket purchase, return the item, along with the original sales receipt to the original place of purchase within 30 days for an exchange or refund. Think of it as a 30-day test ride.
