Chain guide won't fit seat post

My chain falls off when I shift from the 50 to the 36 chain ring. I want to buy a chain guide to prevent this. But none of the three brands will fit the 12cm seat post of my Specialized Roubaix. (The three are Dog Fang, 3rd Eye and the Jump Stop.) Does anyone know of a similar product that will fit onto a 12 cm seat tube?

you just need to adjust your limit screws and or derailluer cable tension. try turning the inner limit screw ie the one closest to the seat tube, a half a turn tighter. if that doesnt work, try anouther half...

You could buy a larger radiator clamp and replace the one that came with the Third Eye Chain Watcher.

A agree that the inner limit screw on you front derailleur is not adjusted properly if this is a frequent problem. The Chain watchers are supposed to be emergency items, not routine shift limiters.
