This is a cheap little device to protect your frame from damage should the chain come of the front rings. Easy to fit and adjust, fitted correctly it does what it should. I bought this when I built up a new commuting bike as the one on the old frame had seized on - but at this cost, who cares?
The device I have on my best bike cost over £30, so this represents good value.

Simple, lightweight, effective
Sometimes the simplest design is the best, and the Deda Dog Fang is a prime example. Set it up correctly and NEVER drop your chain off the inner ring, not even with 15 teeth differences between rings.
