Lezyne Trigger Speed Drive CO2 Bike Pump

Small enough to forget about. Useful enough that you shouldn’t.

If you’re running tubeless or just don’t enjoy standing on the side of the road for 10 minutes with a hand pump, this does the job quickly and without fuss. It uses a CO2 cartridge to inflate your tyre in seconds, with a trigger valve so you’re not guessing how much air you’re dumping in.

The control is the main thing here. Some CO2 inflators are basically on/off. This one lets you ease it in, which matters more than you’d think—especially if you’re trying not to overcook a tyre mid-ride.

What it does well

Fast inflation when you don’t want to hang around
Trigger control gives you a bit of precision
Compact enough for a pocket or saddle bag
Solid alloy build — not flimsy, not precious

What it’s for

Road riders who want a quick fix and back on the bike
Mountain bikers running tubeless setups
Anyone who values time over a slow pump session

What it’s not

A replacement for a proper floor pump at home
Particularly useful if you forget spare cartridges
