Lezyne is a great company who names products in the most confounding way. They’re better than Shimano or Nitto, but that’s not saying much. What is a B112A? Is it a bar? A derailleur? Lezyne names everything ‘drive’, plus some sort of modifier. Here’s a sampling: Lite Drive, Super Drive, Micro Drive, Travel Drive, Tech Drive, Alloy Drive, Alloy Drive (again), Pressure Drive. I have too much Yurt time on my hands so I counted the amount of products with the name Drive on the Lezyne site. 108. 108 friggin’ products named drive something. Or something drive. These people need a new marketing manager. You don’t even drive a bike. You ride one. Unless it has one of those chainlink lowrider steering wheels, then maybe you drive it. Get back to me on that.
Anyway, lots of Lezyne products are quite well engineered. Maybe that’s the problem. Letting engineers name everything. We particularly like their pumps, be it floor or frame. The frame pumps are all pretty great, but we only stock this one. They make 36 different ones, but this is the only one most folks need. It’s small enough to fit in a tool roll. It’s chubby enough to move air with a quickness. It can inflate tires up to about 80 PSI, and if you need more air than that, you have not been reading our site.
It uses a hose to attach the pump to the valve stem. This is genius. Leyzne didn’t invent the hose, old French pumps of dubious quality had it ages ago. In fact, the shape of the pump is also a direct rip on those old french pumps. Heck even the materials! But the Leyzne pump is better than that old french pump you stole off a Peugeot at a church yard sale. It’s made to tighter tolerances. It’s made for big, low pressure tires. It feels solid, more Comte than Epoisses. Being aluminum, when you get to a higher pressure, the pump heats up. That’s good, it’s a heat sink. Aluminum is too rigid to expand with the heat, like plastic pumps do. This is why that crappy old Zefal mountain bike pump you got for 2 bucks at the swap starts to freeze up and get sticky feeling after you’ve put a bit of air in the tire. Cause it’s plastic. The aluminum pump gets warm but keeps working fine, easily and smoothly at high pressures. All the important bits are aluminum, the handle, even, so it’s all one big heat sink. The aluminum machining, plus the hose, means it costs more to make than a plastic pump. Boo friggin’ hoo. Your tubeless tires were at least 55 bucks each, and your rims were probably 100 each. This pump will outlast at least 6 sets of tires, so it’s a bargain.
No pressure gauge, because tiny pressure gauges don’t work well. Use your fingers. What would Bobby Flay do? He’d call a sous chef and have him poke his finger into the tire and see if it was medium rare yet.
The only, only, only catch to this pump is that if you use it with tubeless valve stems, make sure you really snug the valve core into the valve stem, cause the hose can unscrew a semi loose valve stem when you try to remove it. Not a big deal, that little bugger should be tight, but if it’s not, don’t say I didn’t warn you.
Don’t use the plastic pump holder this thing comes with. Do you want your pump filled up with road crud? Plus, it looks nerdy. They call this a frame pump, but that’s a lie. It’s a sack pump, but no one knows how to market a sack pump (yet). Put it in your sack, or tool roll or in the bottom of your pannier to collect dust cause you converted to tubeless.
