With
the bash guard removed and through a progression of overlay pictures,
you notice how the
chain line is very high in the Dualrailleur Guide. This prevents
the chain from dropping on to the granny much like a single ring
chain guide. We have designed the Dualrailleur to utilize the proven
derailleur cage ramping system to maximize shifting efficiency, and
then extended the entering and exiting area to calm the chain as
it travels through the guide. The Dualrailleur has 4 to 6 times the
surface area when compared to just a standard derailleur, so the
chain is actually trapped on the sprockets. Plus you can adjust how
close you run the guide next to your chain. Made of Polycarbonate
(the same material used for bullet proof glass) the chain glides
effortlessly through the guide.
Polycarbonate is much more expensive, but is a harder and slicker
surface then the plastic other companies have chosen to use. We could
have made a cheaper guide but we demand the best performance and
didn’t want to be just another dual ring system.

the only true dual ring guide.
