PSA -- 12 Speed Chainrings for Older Cranksets (110 and 130 BCD 5-bolt)

Praxis is now offering 110 and 130 BCD chainrings compatible with 12 speed drivetrains. Praxis makes a good ring, and for folks looking to use older cranksets (such as power meters) with newer 12s drive trains these should do the trick.

130 BCD rings are only available in 53/39. For 110 BCD they have 48/32, 52/36 and 50/34 sets.

Took delivery today of a 53/39 pair and will be mounting on an SRM / DuraAce 7800 crank to go with an Ultegra 12s DI2 group.
