convertible but not clear
on 3 June 2012
This is the second one of these I have had. I sent the first back because I could not get it to work on Presta valves. I received a refund without problem (thanks) but decided to try again on basis the first must have been faulty and could not find other reviews with same problem. I had same issue with second but took a closer look, and managed to resolve. If you need to convert to Presta (the narrow valve found on most road bikes) - when you remove the small assembly, you need to take the orance plastic part out of the black rubber washer before turning over and reinserting. I had previously just turned the whole assembly over and was unable to get a seal on the valve. I hope this helps you avoid same problem. In terms of the product - it seems a perfectly good pump and the bracket fits on the bottle cage bolts and grips the pump effectively (my pump does not fall off, which is a regular problem for my son).
