HV vs HP pump after running lower pressure?
After switching to wider and tubeless tires, it occurred to me that I might be happier with a "high volume" pump over a "high pressure" one now that I'm running much lower than 90psi now. Anybody find this to be true? Is a HV easier with fewer strokes now that we don't need to pump it up so firm?
If anybody has specific experience with the Lezyne Sport Drive HP and HV, I'd love to hear that especially!

My experience with high volume mini pumps is that it starts to get tough going above 40psi. If you're talking about floor pumps then my experience is it gets tougher around 50-60psi.

HV pumps are usually designed for use with mountain bike tyres, so 20-40 psi tops. I have a Topeak HV mini-pump, but I’ve never tried using it on my road bike tyres at 60-65 psi. I use a Silca Tattico for my road bike and it works fine. I think my HV pump would be hard work at that pressure.

I have four Crank Brothers mini-pumps mounted on my bikes in the active-use lineup. The model I use can be switched between HV and HP. With my pipestem arms, I can get maybe a dozen HV pumps in from 0 psi until I need to switch to HP. Still takes quite a number of pumps to get to minimal riding pressure, but that's OK.

I bought a Lyzene gravel pump with 0-100 psi gauge. Perfect for my 50-60 psi tubeless tire pressure. I also updated an ancient Silca pump with a new and much larger 0-100 psi gauge.

The OP doesn't say mini pumps, just low vs high pressure. I use Zephal HPs and HPXs on all my bikes pumping tires from 38c at 30 psi to 23c at 110 psi. Those pumps handle them all well. (And mini pumps will never win my heart or money. Those HP/HPXs simply work way too well. And yes, sometimes I have to get creative, even modify bikes to carry them. Pan head screws can be shaped on a grinder to make nice pegs.)

Yeah sorry, I should have mentioned I'm talking about mini pumps. Sounds like it would be best to stick with the HP. Thanks!

I have the Silca Gravelero mini pumps and it is higher volume and I can pump it to 70 psi which is the most I need for any of my bikes now, without a lot of effort compared to some older mini pumps I have used in the past. Would recommend.
