Another option: this one does not require removal of the FD attachment bolt, which is nice IMO.

86mm from bolt centre to tip.

I'd pay somebody to buy that and send it to me in the states. I've had my eye on that for over a year for my system six.

I went with the DogFang and replaced the standard bolt with an aluminum one to save a few extra grams. I like the idea of the clamp mount chain catchers, but the Addict has the carbon integrated FD mount that I don't want to put extra stress on (through a significant lever arm). The DogFang works fine when properly positioned.
