Lezyne Pressure Overdrive Floor Pump

The Lezyne Pressure Overdrive Floor Pump is built specifically around the demands of tubeless tire setup — a task that requires more than a standard pump can deliver. Its dual-chamber design lets you pre-pressurize a secondary air reservoir, then release it all at once via a stainless steel foot lever, generating the kind of concentrated air burst needed to seat stubborn tubeless beads quickly and reliably. The body is constructed from steel and aluminum for long-term durability at the track stand.

Day-to-day inflation is handled through the same pump, with an analog pressure gauge providing accurate, easy-to-read feedback. The extra-long nylon-reinforced braided hose gives you flexibility when working around the bike, and the ABS-1 Pro Tubeless chuck is compatible with both Presta valves and M6x0.8 tubeless valve cores — no adapters needed for most setups. Note that when using the pump for standard inflation, the air chamber needs to be pressurized before use, whether you're filling a flat tire or topping off an existing one.
