Anyone bought a presta inflator for a compressor off Ali? Anyone recommend one? The Park INF-2 is $250 AUD which is ridiculous. The Prestaflator Mini would be ideal but they're still $70 AUD for some reason.

Don't need a built in gauge, just a Presta head for a compressor
did you ever find one? Mine's getting kinda old and slipping a bit. Could be time to replace it...

I recently picked up this one. I am using it with a shitty pancake compressor that someone gave me, so inflation power and speed isn't very good. It's certainly not blasting hard-to-seat tires onto my rims.

As far as the unit itself, I hate the plastic flip-lever inflator head, but that is par for the course: most plastic flip-lever heads that I have on floor pumps are mediocre as well. This head neads to be held squarely onto the valve stem with my other hand or else air leaks around the valve, but again that is common for most plastic lever heads I've used.

I plan to modify this to take a Lezyne-style screw-on presta head. (Yes, I'm aware of the valve unscrewing issue with those too.)
The rest of the prestaflator unit seems fine, though it seems like a $25 item, not $50.

Any of you ebay / Ali experts find a Chinese knockoff of the $90 SRAM Ultimate Piston Spreader yet? Looks like a nice tool, but no way I'm paying $90 for that.

I use a small c clamp from harbor freight that I ground the head down to fit in the calipers. Do 1 piston at a time.

I've got tire levers and the Park piston pusher for doing 1 or 2 pistons at a time from 1 side. What I like about the idea of the SRAM one is that it pushes both sides back evenly. I figure that it's probably better for the seals & such.

I have an original prestaflator with the push on chuck.
I got a few rubber sealing doughnuts at the same time, but the last one is about half done. I should start to look for its replacement. I don't like the removal by pulling sharply and hoping you don't sever a finger on a brake rotor though.
