PRAXIS BUZZ CHANRINGS 110 - BCD 52/36 10/11/12 SPEED
The Gold Standard in Shifting Precision.
The Praxis Buzz Chainring Set is engineered for riders who refuse to compromise on shifting speed or drivetrain rigidity. Designed as a premium upgrade for 110 BCD cranksets, these rings are world-renowned for their "Leanda-Shift" technology—a complex system of machined shift ramps and stainless steel pins that provide arguably the fastest and most reliable shifting in the industry. Whether you are sprinting for a finish line or shifting under load on a steep alpine climb, the Buzz rings deliver a crisp, instantaneous chain movement that rivals or exceeds original equipment.
Unlike many aftermarket rings that are stamped, the Buzz set is One-Shot Cold Forged from 7075-T6 aluminum. This unique manufacturing process creates a denser, harder grain structure, resulting in a chainring that is significantly more wear-resistant and stiffer than traditional CNC-machined alternatives.
Key Features
One-Shot Cold Forged: Constructed from 7075-T6 Aluminum, providing a harder-wearing surface and superior tooth stiffness compared to CNC-machined rings.
Leanda-Shift™ Technology: Features complex, individually timed shift ramps and stainless steel pins for incredibly fast and consistent upshifts and downshifts.
Universal 10/11/12 Speed Compatibility: Engineered with a specialized tooth profile that works flawlessly with Shimano, SRAM, and Campagnolo 10, 11, and 12-speed drivetrains (including Di2 and eTap).
Hard Anodized Finish: The "Black Bird" finish isn't just for looks; the hard-anodized coating reduces friction and extends the life of the rings in gritty road conditions.
110 BCD 5-Bolt Pattern: Designed to fit standard 110 BCD 5-arm cranks, as well as 4-arm cranks when used with the appropriate Praxis specialized spider or hidden-bolt setups.
Increased Rigidity: The reinforced "Buzz" design minimizes ring flex, ensuring that every watt of power is transferred directly to your drivetrain.

✅ Why This IS For You
Performance Road Cyclists: If you demand mechanical perfection and want the fastest shifting possible from your mechanical or electronic groupset.
High-Wattage Sprinters: Perfect for riders who produce high torque and need a stiff chainring that won't flex or "rub" against the front derailleur under load.
Drivetrain Mix-and-Matchers: Ideal if you are running a custom setup and need a set of rings that play perfectly with Shimano, SRAM, or Campy chains.
❌ Why This May NOT be for you
Compact Gear Seekers: If you live in an extremely hilly area and prefer a 50/34T setup, you may find the 52/36T "Semi-Compact" gearing slightly too tall for the steepest ramps.
SRAM AXS 12-Speed (Road): While compatible with standard 12-speed chains, these rings are not optimized for the SRAM Flattop chain profile specifically.
BFC Pro Tip
The Praxis Buzz rings are a staff favorite because they simply work. Because they are cold-forged rather than CNC-cut, the teeth are incredibly tough—but the secret to their longevity is a fresh chain. We always recommend installing a new chain when you fit these rings to ensure the best interface and to prevent "premature wear" from an old, stretched chain. Also, when installing, make sure the drop pin (the little silver stud) is aligned behind the crank arm—this prevents your chain from getting wedged between the arm and the ring in the event of an overshift!
