While I'm waiting for the replacement I still need to ride--hence the 1100. I learned a bit about so called high end pumps and it seems the majority of them come out of the same 3 factories in the Far East. Depending upon who the brander is the pumps are made to different specs but Chinese manufacture has come a long way. The Schwinn 1100 is no exception. For $17 I can't believe the quality I got. A solid well painted steel barrel and a 5-in-1 switchblade head that works just fine on my presta valves. Took the tires right up to 105 psi ( a bit short of 116 optimum) once I learned how to properly engage the solid and weighty aluminum lock. You can disassemble the rubber and plastic components of the washer head and reassemble it to handle presta without any adapter, even though the pump comes with the standard brass screw on adaptor. The gauge is accurate and the rubber tubing has joints that can be adjusted. Pump build is excellent. I don't think you can say "cheap Chinese junk" and be accurate anymore. Holy cow.
