That's just mud and grime. it will clean up fine. I've had my mini-morph mounted in the same location, first on my road bike for ten years, and later on my hybrid for a year. I clean it occasionally, and disassembled it once for deeper cleaning. There's nothing in that photo showing an impossible restoration.

If you ever get any presta valve tubes that have replaceable valve stem cores, the core can stay in the pump chuck when you take the chuck off of the tube. But most cores do not come off, so you might never run across that.

Yea, I did have to tear it apart and give it a good cleaning and if I remember correctly, I had to replace a small piece or two in order to make it functional again

I'm sure most know but the Lezyne pumps now all have a small bleeder valve in the chuck that allows you to remove any air remaining in the chuck after you're done pumping, which supposedly helps to prevent accidentally removing the valve core when finished but I've still had it happen. And so I always tighten down that Presta valve core when you get that new tube and sometimes even add a little plumbers tape to the threads so as to prevent that from loosening up.

The topeak pumps work well. Another consideration would be those by Silca. I have the Tattico and it is well made. The couple of times I have used it it has worked well.

I have experience using a Lezyne and my current Topeak frame pump many times. I haven’t had a chance to use a topeak mini.The Lezyne is a quality pump, no question, and it gets the job done, but I find the screw on attachment method kind of annoying(the last thing I want when I have a flat is an annoying time fixing it), and I have also had an issue with a valve core that kept unscrewing with the pump. It’s a well made, nice pump, but has it’s little hang-ups.

i love my topeak frame pump. It’s worked perfectly to pump up Many tires with never an issue. It’s a bit easier to use than the mini pumps I’ve used. I also think the longer barrel makes pumping up a tire easier than the little pumps. I can hit over 50psi no problem with it. No problem meaning it’s not a lot of work like I’ve experienced with minis. I don’t run my tires higher than ~50psi, so it works great for me. I think people say higher psi is easier with a frame pump than a mini. It’s not as compact, so that’s it’s one negative as I see it, but it’s worth it to me for the ease of use.

A friend of mine commented once that he used blue (removable) threadlocker on presta valve cores to help hold them in. Since then I have done the same, but I have not used my Lezyne pump on any of those valve cores since, so I can't comment on how well it works. I do remember being careful to try to make sure that the threadlocker only went on the threads but not anywhere near the valve where my concern was that it could cause a slow leak.

I know most of you won’t take this seriously, but I’ve been using a Schwinn mini-pump for awhile now, and like it quite a bit. 👍 This particular one has a gauge that reads up to 120 psi, a short hose, openings for both Schrader & Presta, and a weird rotating foot rest thingy, to make it work like a floor pump. Seems like those are the same features everyone wants, on the more popular names. 😉 BTW, I’ve used it many times now, and it really is pretty user-friendly.

Rock on. It's always awesome to find gear that works for you at 1/3 the cost of the nice expensive stuff. That's how I usually end up with nicer touring bikes for cheap(used, very good condition stuff, build up the bike myself), but usually end up spending too much on camping gear. You Rarely come across high quality, barely used gear for pennies compared to new price. A brand new pump that you like is even better than barely used!
