LEVATIME SHIFTING

Snappy Shifting

BALANCED FOR SHIFT QUALITY

The highest overall shift quality is our primary goal and what we constantly strive for. In order to get there, we focus on a balance of five main attributes: Stiffness, Weight, Durability, Shift Features, and Price. 

Many other companies tend to focus on just one or two of these attributes, and then the shifting quality suffers. Praxis Cold Forged chainrings are simply the most balanced rings available in order to deliver the highest shift quality.

NEW GENERATION SHIFTING

NEW GENERATION : LT2

Our original LevaTime™ rings were the product of years of relentless testing and tweaking.  The final result is a set of some of the finest and fastest-shifting rings available.  To this day, our Buzz family of rings are still considered by many to be some of the best shifting rings available.But our engineers were not content to sit still.  Behind the scenes we kept pushing, testing and tuning for faster shifts and smoother shifts.   We went further than we ever have in creating our new LevaTime II™ X-rings.

Now updated to a new stiffer 5mm big ring, this allowed our engineers to increase the amount, and type of shift features we could forge into our X-rings.  This new foundation also allowed us to implement our new fast engaging forged shift pins to improve shift speed.  Holding it all together with even better support is our beefed-up LT2 forged X-Spider.

LOOK CLOSE : No two teeth are alike. One thing many people notice right away is the complex shaping of the teeth on a Praxis chainring. With all the duties required of a chainring for smooth shifting, we needed to sculpt very elaborate tooth profiles to better control the chain during upshifts and downshifts. By forging a chainring where no two teeth are alike, we create a ring-set that allows the chain to smoothly move laterally and vertically.

After riding these new rings, you’ll realize these aren’t your average, ordinary chainrings. 

LevaTime II™ takes shifting to the next level.

MATCHED SETS

Like all great marriages in life, timing is everything. A large part of our LevaTime™ shifting system is the timing and clocking of the outer and inner rings together. All of the Praxis LT1 and LT2 gearing combinations are “Matched Sets” precisely designed in concert for an optimized shifting experience. 

Praxis engineers spend an obscene amount of time laboring over tooth shape, ramping, and the precise location of shift elevators. All of this is done in order for the inner and outer ring to be in perfect sync at the moment you shift.

SHIMANO™ — Our X-Rings and Buzz Rings shift great with the new Shimano 10/11/12sp chain and drivetrains (Di2 included). Our X-Rings are made just for Praxis X-Spider cranks. Our Buzz Rings are made to be mounted on traditional 5-arm cranks, and also work with 4-arm w/hidden 5th cranks (SRAM Exogram). They also work great with traditional 5-arm mount aftermarket cranks such as THM, Rotor, Cannondale, Specialized, LOOK and FSA cranks. *Our rings do not mount to the newer generation Shimano cranks with their custom asymmetrical BCD.

SRAM™ — Our X-Rings and Buzz Rings shift great with the SRAM 10/11/12sp chain and drivetrains (AXS included). Our X-Rings are made just for Praxis X-Spider cranks. The Buzz Rings are made to be mounted to traditional 5-arm SRAM cranks, and also work with 4-arm w/hidden 5th SRAM Exogram cranks. The Buzz Rings also work great with traditional 5-arm mount aftermarket cranks such as THM, Rotor, Cannondale, Specialized, LOOK and FSA cranks.

CAMPY™ — Our X-Rings and Buzz Rings shift great with Campy 10/11/12sp chain and drivetrains (EPS included). The Buzz Rings are made to be mounted on traditional 5-arm cranks, and work with 4-arm w/hidden 5th cranks (SRAM Exogram). *Our rings do not mount on Campy cranks with their proprietary Campy BCD/Design. Example…you would use a 3rd party crank like a Specialized, THM, Rotor, FSA, SRAM etc. crank with our rings and then the chain and derailleurs are Campy. Our X-Rings are made just for Praxis X-Spider cranks and these shift great with Campy 10/11/12sp chains.
