    My Shimano Nexus 3 speed finally failed after 3 years of hard riding. 1st gear no longer works, but 2nd and 3rd are fine. The hub was under water during a hurricane last year, but I don't know if that was a factor. Anyone know what part is likely to be the culprit? I've never worked on these and have no idea how to diagnose the problem. The bike is fine on the road without low gear, but I use it a lot when riding trails, etc. DSCN3116.JPG DSCN3115.JPG

    I've been riding for about a week with no first gear and so far 2nd and 3rd are holding up. The upside to this failure is the fact that I now have a neutral which is helpful when you start your engine and it revs beyond engagement of the centrifugal clutch. As soon as I get my other bike up and running I'll pull the wheel and check it out.
