Effective shock pump

my superdooper Lezeyne one fell apart the first time I used it

Yeah they do that. I gave up when the replacement they sent did exactly the same

The trouble is the high pressure. A normal track pump isn’t going to get to 250PSi, even some kind of super roadie one isn’t likely to get there. FWIW it takes a lot of effort to get my tubeless pump to fill its chamber much beyond 100PSi

Because of the small chamber in the fork/shock you generally just want to repeatedly shift small amounts of air to get to the desired pressure.

The only fix that comes to mind is swapping the shock for something with a coil spring

1) can I use a floor track pump (gently)

No, they only go to about 180-200 psi (super dooper track/velodrome pumps).

Only thing i've seen is a shock pump with a curved/cupped rubber foot that you can press against the frame, like old school roadie frame fit pumps. And i've no idea who makes them.

You might be able to fabricate one from Sugru though.

Specialized used to make one, the 'Airtool UHP' specifically for rear shocks but I don't think it is available now.  Can't think of any others but surely they must be available for workshop use?

Can you one-arm it? Brace against the frame?

Slight threadjack, Lezeyne shock pumps are to be avoided?

I've been making do with a cheap shock pump for years & am looking to buy a decent digital pump.

I had settled on Lezeyne, but now I've got doubts. Can anyone suggest a reliable accurate digital pump?

I've been using a Syncros digital for years. Not the cheapest but easy to use and durable.

I'm also on the lookout for a better shock pump, I've got a Beto one which is ok for forks but when a shock or seatpost needs really high pressure ~300psi it's very difficult to get there. All the online reviews seem to suggest Lezyne but perhaps not based on this thread...

Small Nitrogen cylinder and regulator?

DC1988 Rockshox's high pressure shock pump (600psi) is about the best I've used for 300psi+. It's still hard work, but better than any of the std size I've used

leegee - I also have a Synchros digital one and would recommend it

Lots of those small cheap car 12v compressors claim to be rated to 300psi. I’d be amazed if they’d manage it, but one might do the bulk of the work and finish it off with a hand pump, so to speak.

You could call someone like J Tech to ask. I spoke to them about shock pumps a while ago. I wasn’t quite following what the guy was saying, but he seemed to be suggesting they had a method to quickly inflate (DH forks in this case at 210 psi) and then tweak at the end. Might be worth a phone call.

Air compressor to the MAX BABY!

Though my DVO one seems fine DVO have a procedure to set up the pump iirc so it loses less air.

Sometimes cheapy Halfords pumps are great to use smoother and lighter to handle at higher pressures ime.

RS ones are complete crap

Beto make the Halfords ones (and loads of others), they're really good.

From my experience yes. Both fell apart and they seemed to have forgotten that you actually needed a place to hold the thing
