Joe Blow Sport II track pump – knackered after less than a year
Would say not Graham — I revitalised my Joe Blow (Sport possibly) – somewhat similar to yours but silver barrel – last year, which was after purchase 8-10 years ago..
It has a twin head system – lever to direct flow – and TBH I’ve never had problems, works well for me.
Form LBS? they may be able to contact distributors (Madison? my LBS got me a new gauge assembly when mine threw a wobbly for a while) (or you could contact Toepeak directly).
Edit: Mine’s a Joe Blow PX, but functionally the same. Gauge is at the top of the barrel, but it has a twin head system as yours does.
And… it’s not needing the cap on the twin head to be tightened, is it?Posted 3 years agoRoter SternMember
You can buy the heads separately for a few quid (I have just replaced mine after six years of use) but I would say you should get a new head/pump under warranty.
Edit: Just a quick thought. Is the air definitely escaping from the head? It just occurred to me that I had a similar problem last week or so I thought until I realized the little cap just above the base of the pump wasn’t tight. A quick tighten and voila!Posted 3 years agovertebratetomSubscriber
I’m pretty sure you can take the entire head apart if you need to. I’ve certainly done it on an old one. Unscrew the end bits, get a big scewdriver on the side opposite the lever … (something like that anyway, can’t really remember).
That said, I’ve had two that have knackered in under a year. I won’t buy another.Posted 3 years ago

Got it from Evans (store not online) if I recall correctly.
Might be worth a shot.
Is the air definitely escaping from the head?
Yep. If I put my thumb over the Schrader bit then I can lessen the amount of air escaping.
Unscrew the end bits, get a big scewdriver on the side opposite the lever …
Opposite side of the lever is a flat disc with two little holes in it.
Sort of like this but with no big hole in the middle:

Bought a Joe Blow track pump under a year ago thinking “That’ll be an excellent replacement for the crappy old no-brand plastic one. Should last me a good while that”
Tried inflating some Presta tyres with it the other day and the “revolutionary” TwinHead™ is leaking air out of the Schrader side so fast that I have to keep pumping to stop the tyre going down.
Worse still there doesn’t seem to be any way to service the internals of the valve (you can unscrew the end bits and get to the first rubber bits, but not to the actual mechanism that the lever operates).
Is that pretty typical for those pumps?Posted 3 years ago
Head on mine is fine, but the non-return valve at the base … well it does return.
Is there a definitive answer on who the distributors are so I can ask at the LBS, or pick the right LBS to ask? (SJS Cycles do have the part I need listed, but their postage more than doubles the cost).Posted 3 years agobirdageMember
Mine screwed up within a couple of months having never worked properly. Whilst trying to sort it I lost the valve ball (think it was that) and then looked for ages for parts but couldn’t work out what from internet descriptions whether they were the parts I needed. Probably needed everything but the main body. Still mean to sort it out but the cheaper replacement Pedros I got has worked flawlessly for the last 2 years.Posted 3 years agoSuggseyMember
My one the same as OP’s one has been blowing strong for the past ten years but the gauge has always been woefully inaccurate! I’m going to ask as my mate borrowed mine and was cussing as it was leaking air faster than he could pump until I pointed out that the levervhad to be locked out in the opposite direction ie away from the rim for the correct air flow through the correct valve in the head!Posted 3 years ago
Took it to Evans.
They said they couldn’t do anything, but could order in the parts for me to fix it.
Then called me today and said the parts would be £17 and they’d be special order so I’d be better off getting them from Wiggle or Chain Reaction.
Think I’ll just buy a Lezyne one.Posted 3 years ago
