    shifting problem only when cold?

    On my rapid fire shifters, when it's cold, the front shifter doesn't want to grab the cable only when going form the middle to the big ring. I need to try numereous times to try to get it to grab including slightly pushing up while pushing it to coax it. Any ideas? The problem resurfaced today as the commute was at 32 degrees. Thanks

    What's the story on your cables (i.e. how old? how's the routing? etc.)

    Sounds like you're getting a bind when the mercury drops. Might be time for new cables. Also, what's the cable routing like? Check any points where the cable is not inisde housing (i.e. if it wraps under the BB) for binding or crud.

    The cables are new. I don't think it's the cables. The shifter doesn't want to grab anything. It's like there is nothing at all attached to it. It just flops with zero resistance. I'm not sure what the inside of a shifting mechanism looks like or how it grabs the cable. Shifts fine from the small to middle ring.

    There is a protective cover that you can take off, it's two small screws, do that and lube it with a good slippery lube; that is my opinion. When you place the cover back on make sure you use blue locktite.

    I had the trouble when it got really cold for a while, it turns out that the lube inside the pods was freezing. Try lubing them with something that doesn't freeze right before you ride and see if that helps.
