Topeak Joe Blow Sport II Floor Pump
This unique mountain bike specific floor pump features a super-sized steel barrel designed to deliver the higher volume required of large off-road tires and an extra sensitive, base mounted analog gauge with air release button to help dial-in the exact pressure. A TwinHead with extra long hose, oversized padded handles and stable composite base make the JoeBlow a must-have.
The TwinHead technology gives riders the best of both worlds. Presta valve internals on one side and Schrader valve internals on the other, this easy-to-use dual pump head design makes tire inflation chores a snap. No adapters or swapping out pump head parts, simply choose the side you want, press onto valve stem, flip the locking lever and start pumping.
Designed with a new easy-to-read chronograph-inspired pressure gauge with PSI and Bar index.
Oversize/overweight charge applies to this item.
I've been using this pump for 6 years. The rubber gasket for the presta valve started leaking 6 months ago. I was able to buy a replacement parts to keep it going. I serviced the pump a few years ago and its holding up well. Solid purchase.
I've used this pump on both presta and schrader valves up to 100 psi and it works great. The best part? There's no trick to switch between presta and schrader - the dual head will accomodate both. The pump itself is sturdy and well made (as are most Topeak products) and the gauge is accurate. If you need a reliable pump that will last forever, look no further.
there's a couple of problems with these pumps, as other reviewers have pointed out for this pump and the original sport. - the head can be difficult to get a seal with, especially on the presta side. it may take several tries before being able to get air to flow, - the dual head is large, making it difficult to get onto smaller wheels with closer spokes, - the hose material is a cheap plastic, not rubber - it quickly starts to crack wherever it's bent (near the outlet and where it's stored over the handle) and soon blows out. their support company, todson, refuses to warranty the hose even though it's a material defect. instead of paying them a third to half the cost of a new pump, get 3/16" fuel line from your local auto parts store. fits perfectly, will last a lifetime, and only costs about two bucks!
Excellent quality and great features. Probably the best floor pump I've bought.
So far, so good. I've only used with Presta valves so far, but I like the option to use with Schrader without changing the head. Connects easily to the valve. No problems yet inflating both my tubeless mountain bike tires or my road tires. Only tried up to around 95 psi, with a bit of resistance up at the higher pressures, but it did the job. The dial is easy to read. I'd recommend it.
Some pumps give you a ton of airflow but too much resistance, others only pump at the last bit of the compression. Then there's the Joe Blow. Smooth with plenty of airflow and low resistance. I have seated many tubeless setups with this pump. The gauge is pretty easy to read, with a marker that you can set to match up the pressure to your planned level. And that color scheme looks awesome.
