Lezyne Digital Pressure Overdrive Tank Floor Pump - Black - 2018
Description
This is an innovative floor pump with an integrated system designed to seat tubeless tyres. A secondary chamber can be manually pressurised and the stainless steel foot-lever releases the compressed air. This discharges a strong, continued blast of air that quickly seats tubeless systems. Equipped with super accurate, custom digital gauge. Durable steel and aluminium construction with stylish wood handle. Extra long, nylon-reinforced braided hose. Presta and Schrader compatible ABS1 Pro chuck.
When using the Pressure Over Drive as a regular pump, air has to fill the chamber before it will start to fill an empty tyre/tube. This may take numerous strokes before the tyre/tube begins to inflate. When topping off a tube/tyre that already has pressure in it, the chamber will have to reach the same pressure the tyre/tube is at first before it will begin to inflate it further.
Max Pressure: 220psi | 15bar
Air Release: The chuck has an air release button but note that this functions differently depending on what type of valve is being used.
- Schrader: Allows for an infinite release of air to fine-tune the tyre pressure.
- Presta: Releases air from the hose to aid with removal without unscrewing the valve core. Does not allow for the fine-tuning of air pressure when used with Presta valves.

Perfect for tubless inflation, gauge not so relevant.

I had no problems at all using this pump to help setup some tubless tyres (27.5 x 2.8/2.6 DHF/DHR) on my MTB. I did remove the core of the valve to increase the airflow. As this was my first time running tubeless it took a few attempts before I had the procedure down.
I did find that the only reason I used the gauge was to ensure I had enough pressure in the tank. Around 150psi was enough, typically it would still be around 40 psi when I was done; I still found myself using a separate digital gauge (TOPEAK, also from MTB Direct) to fine tune the pressure. So you could probably spend less cash (~$20) and go for the pump with the analogue gauge instead (if you already use a separate digital gauge).
Tubeless setup a breeze

Using to set tubeless tyres is awesome. Build Quality is amazing and apparently everything on it is replaceable. The ABS-1 is a beautiful piece of kit. Even has a valve core remover at the back of the chuck.
Initially was disappointed it didn't come with the ABS-2 chuck, but after contacting Lezyne they have discontinued it because users found it too hard to use and there had been sealing problems as it wears. The ABS-1 pro has worked flawlessly so far. I haven't unscrewed a valve core with it yet (always let the air out of the hose first. Lezyne advises to put a bit of loctite on the valve core but I haven't had to do that yet.
Using as a track pump is a bit awkward. The air tank needs to fill with air so it takes a few more pumps than with a normal track pump. With presta valves you can only get an accurate pressure reading when inflating. Using the deflate button only lets air out of the chuck/hose, not the tyre. So you can't inflate the tyre, then deflate to desired pressure. Apparently this is a design feature to prevent the valve core from unscrewing upon removal. On Schrader valves it's a different story - you can deflate using the chuck button.
When pumping up to desired pressure, the digital gauge has been accurate to within 1 psi when compared to my Topeak digital gauge.
Comes with inflator needles for footballs etc but nowhere to store them on the pump, unlike my old Joe Blow mountain pump.
I had a problem within about the first month with the main o-ring being destroyed. I contacted MTBdirect and they sorted it very quickly - great service from MTBdirect and warranty from Lezyne.
