Bests & Worsts Reviews from Amazon

As background, I build bicycles and own several bike pumps. For portable pumps, I own an older model Zefal frame pump and a Topeak Road Morph G Mini. I will be comparing this Pro Bike Tool pump with my older pumps. The Pro Bike Tool pump is quite handsome, made with machined aluminum and textured for better grip. As the name of the product suggests, the pump is indeed "super compact." It measures under 7.5in in length and is less than 1in in diameter at its widest point. For weight weenies who are concerned about the total weight of their biking equipment, this weighs ~101g (~3.6oz) pump alone and 118g (4.2oz) with the mounting bracket. The pump has two rubber caps to keep dust out. Uncapping the top reveals the flexible hose, which was tucked tidily away within the body of the pump. This hose is rather unique, supporting Schrader valves on one end and Presta valves on the other. The hose screws onto bottom of the pump and the o-rings ensures an airtight seal. The other end of the hose then screws onto the bike tube valve. Due to its small size, each pump does not move a lot of air. It will take upwards of 40 pumps to get a usable volume and pressure into a road tire. This should be expected for the size of the pump and is not a fault of the pump. The pump operation is smooth, but attaining high pressures is difficult. Pros: - Pump utilizes a flexible hose, which is very important. When pumping, you are bound to push back and forth, no matter how well you try to brace the pump. This movement causes strain on the tube near the valve, possibly causing tube failure. My older Zefal did not have a hose and I lost a few tubes as a result of using that pump. As a result, I got my Topeak pump that also has a hose. - The screw on valve design works very well on both Schrader and Presta valves. Screwing on the valve takes a bit more time, but you get an airtight seal every time. There is also less air loss when engaging the valve. - Very compact. It's the smallest pump I have come across, which makes it a great component for an emergency patch kit. - Lifetime warranty against manufacturer defects Cons: - It claims to reach 120psi. While it may be possible to reach this value in theory, in practice, it is very difficult to go above 80psi. The design of the pump requires you to hold the pump with both hands - one hand on the handle, one hand on the body - then squeeze your hands toward each other. Perhaps I'm just weak, but by 80psi, this becomes near impossible. Unlike a floor pump, you can't use your weight and gravity to assist you. The Topeak Road Morph gets around this problem by essentially designing a mini floor pump and can reach 100psi much more easily. - The mounting bracket has holes spaced perfectly to screw in place of a water bottle cage. However, due to the bracket design, the pump ends up lateral (left or right) to your frame instead inline in the frame triangle (see photo). This seems intentional, to keep the pump to the side of the water bottle cage. On my frame, it prevents me from mounting it upright on seat tube because it will get in the way of the front derailleur. It can be mounted on the down tube, but depending on your bike, it can come very close to the crank rings or crank arms. Also, some older steel frame bikes do not have mounting holes, making the mounting bracket unusable. A better solution may be a rubberized bracket fastened by zip ties. If you buy this pump with appropriate expectations in mind, this pump may serve your purposes. For example, if you ride a road bike at over 100psi and was hoping to have a portable pump to keep you topped up, then this is not for you. However, if you need a portable pump for low pressure tires or need an emergency pump for on-the-road patching, this would be ideal. In summary, this pump features a clever flexible hose design with secure, airtight seals. If your priority is ultra portability, then this is ideal. But if you are hoping to reach high pressures on a portable pump, then this is not what you need. Of note, I received this item at a discount in exchange for my honest, unbiased feedback.
