Praxis Works Buzz 110BCD 48/32T Double Road Chainring Set 2Tone Black

Praxis Works have custom designed this 110BCD, 32/48T Buzz Double Road Chainring Set especially for their 110 BCD cranksets and Specialized alloy 110BCD spiders. Purpose-built to be compatible with both 5-arm and 4-arm w/hidden 5th road cranks this set requires a chainring bolt to actually thread into the inner ring rather than using a threaded nut. The resulting chainring set is one that will get you up some of the steepest hills around.

One-Shot, Cold Forged Manufactured
These Buzz One-Shot, Cold Forged manufactured rings also incorporate LevaTime shifting technology making them the fastest-shifting rings available. Made with hard anodised 7075 T6 aluminium this double chainring set (with 110 Bolt Circle Diameter) comprises a 48T chainring and a smaller 32T ring, each having cold forged tooth profiles for greater strength and durability. To keep things neat & tidy, the larger ring comes with a plug to place in the threaded hole you're not using.

Installation
The 48/32 chainring combination is only compatible with Praxis 110 BCD cranksets, which have specially-designed chainring mounting tabs. This specific chainring set includes a set of custom chainring bolts required for installation. It will not install on prior generation "TURN" road cranks or other brand cranks. That aside, Praxis Works chainring sets are as easy to mount as any other chainring. The only other small difference is the short or long catch pin and placement. Just align one of the two pin holes with the crank and then select the long pin if it will fit, or if not use the short pin. After installing the pin you can then grease and mount your chainring bolts. As with all threads, and metal-on-metal interfaces, it is highly recommended you use high quality grease for this task.

TECHNOLOGIES

Chain Pin
The trick to being multi-compatible is the two placements options for the catch-pin. The chainrings come with both a long and short catch pin supplied which can be located at either end of the chainring depending on the cranks they are going on and how thick the arms is.

Cold Forged
All Praxis Works road chainrings are created with a superior manufacturing process which cold forges 7075 T6 aluminium chainrings with more tooth detail than ever before and also allows them to manipulate the ring shape too. The "One-Shot" forging process delivers a harder/tougher overall chainring tooth surface for added durability and also allows for more shifting features to be added to the ring than traditional CNC manufacturing allows. Individual tooth profiles, alternating tooth angles, timed ramps and tactically placed shift elevators are all jam packed onto the Praxis Buzz ring. With the cooperation of some of the most cutting-edge forging presses in the world Praxis are now creating one of the most durable and consistent shifting rings ever produced for cyclists. Fun Fact: The forging machine used to produce a Praxis 32t mountain ring is 2 stories in height and uses over 1000 tons to complete the task.

LevaTimeT
Chainrings employing the LevaTimeT shifting blueprint feature several shift pins placed strategically at points on the ring to provide a perfectly timed lift. Synchronized ramps are tuned with a specific inner ring, providing a clean channel for the chain to move upwards. Each individual tooth is sculpted to handle a specific duty. Along with that, precisely located scallops help to control chain movement and prevent chain suck.
