Lezyne

I have had the Sport Gravel Drive Floor Pump for a couple of years now. The stock screw on pump head was horrible / awful / terrible / no bueno. This Presta-only head is a beautifully machined product that works very well. At $30 it should be wonderful, and it turned a $50 pump into an $80 pump so it only gets 3 stars for value. But if you have a Sport Gravel Drive Floor Pump (or any other Lezyne floor pump with that terrible screw-on head) and you don't want to just throw it out, this is the fix as long as you only need it for Presta valves. Installation is easy. Just cut the tube as close to the old head as possible, lubricate the inside of the tube, and install the new head.

I grew up with shrader style tire valves so when I got my Trek FX3 5 years ago, Presta valves took an adjustment period. I bought a $30 Serfa pump from the local store. For a long time, I thought it was my fault that my fingers were getting smacked when the pump head handle would snap back. And I didn't understand why it was so difficult to get the pump head to seat properly on the valve. After learning that I needed to replace bent valve cores, I decided it was time for a better pump.

I shopped around and picked this one. It's a major improvement. It's so much easier to screw on the chuck head, pump it to exactly the desired PSI and unscrew the chuck. Inflating tires is much easier and pain free.

I ride a race bike on semi-rural roads in Northern California and use a both flashing taillight and small rear view mirror attached to my glasses. Occasionally oncoming cars will enter my lane to pass and it's clear they either don't see me or don't care that I'm there. This light addresses the former drivers. It is quite bright even in sunlight. It is also small and virtually weightless. My mirror saved my life once, so I am aware that there are.both homicidal as well as distracted drivers out there. This light helps minimize the threat from the latter.

Overall, these work as they should for my tubeless setup. Was able to remove the valve core easily with the cap (nice feature, btw), add sealant, and it holds air. The thick collars are easy to tighten and look nice, but ended up being too thick for me to fit a pump head onto the valve. I have 50mm wheels, a fairly common depth, and figured the 60mm valves should work. They do, but I had to use a standard collar from a spare inner tube. If the valves were around 65mm they'd probably work without issue, and would be 5 stars.
