The pump head on my Joeblow Sport 2Stage recently blew out (the lock arm literally blew off the head). I’ve been looking for a replacement, but im struggling to find a vendor, and the local rep search for my area only shows bike shops that have been out of business for 5 years. The below website is closest over found, but unsure if it’s a legit site, appreciate any guidance:
https://www.bikestopeak.com/topeak-twinhead-dx5-for-joeblow-sport-iii-and-mountain-x-online/
In the US, the Topeak distributor is Todson.com . Sorry, can’t help if bikestopeak is a legit site, but searching the part# TTH-DX01 turns up a few other sites as well.
I replaced my Joe Blow pump head with one from Todson. It was a mixed experience. I ended up buying a pump head that I didn’t know would also require me to buy a new hose. It took a number of emails with them to figure out what I was supposed to do and how everything fit together (though they were very responsive). In the end, everything works, but I don’t like the new pump head, just too hard to pull the lever. But on the other hand, it extended the life of the pump, so that’s one fewer big metal thing in the landfill.
