Rock-Solid Stability. Explosive Speed.

UNI-CORE integrates both sides of the bottom bracket into a one-piece structure, enhancing spindle alignment and overall structural rigidity while minimizing misalignment and torsional flex caused by high-output pedaling. With a more stable core structure, UNI-CORE significantly improves crank spindle rotational stability, reducing frictionThe one-piece core of UNI-CORE is engineered for faster, smoother, and more efficient pedaling performance. caused by torsional distortion and unleashing every pedal stroke into faster, smoother, and more explosive forward momentum.
 

WHY? 

T47-Proven,But Not Perfect

The traditional two-piece BB structure still limits alignment precision
 

● Separated left-right structure

Susceptible to tolerance stack-up, reducing alignment precision.
 

● Discontinuous structural design

Potential deformation under high load, affecting efficiency and stability.

WHY? 

STRUCTRAL EVOLUTION

Same T47 Frame. One-Piece BB Evolution

 

 ➀    Frame:Ø47mm Standard Threads Interface
 ➁    Sung-Fit Ring:Thread-to-Press-Fit Conversion
 ➂    UNI-CORE one-piece BB system
 ➃    Versatile BB Width Options

• Standard T47 frame interface
• One-piece UNI-CORE bottom bracket body
• Drive-side single-side locking system
• Non-drive-side dedicated sleeve
• Threaded interface converted into a smooth press-fit support surface
• Non-drive side is compressed and secured as the BB is locked from the drive side
   

STRUCTURE TECHNOLOGY

	UNI-CORE is a one-piece bottom bracket architecture that integrates both sides into a unified structure, eliminating axis misalignment and torsional distortion common in split BB systems under high loads. By maximizing structural rigidity and axis consistency, UNI-CORE enables smoother rotation, lower resistance, and more efficient transfer of pedaling power into forward momentum.
	The 3 in 1 Core System BB set can accommodate for three different crank spindle specifications. Easily switch between different cranks without the need to change the Bottom Bracket.
	G3-grade perfectly round ceramic balls create lower rotational resistance, allowing your power better to convert to speed.
	The ceramic bearings utilize G5-grade ceramic balls and are paired with precisely machined steel race, delivering excellent rotational performance for riders.
	NC Race Bearings have a Nano coating on outer & inner races, This dry film can minimize the coefficient of friction to as low as 0.03 dynamic, and 0.07 for static. The Nano Coating overcomes or reduces mechanical lubrication problems improving performance and extending service life >300%
	ZERO Contact Seal, a non-contact bearing seal, provides complete coverage without increasing rotational resistance, striking the optimal balance between efficiency and protection.
	Patented plastic-steel bushing design protects Press-Fit BB shells from wear, while the snug fit eliminates noise and corrects bottom bracket tolerances.
	While Supra LV is focused on pure Performance of the Pulley Wheel, TRiPEAK chooses a different  lubricant character for the ceramic bearing Bottom Bracket: The Eterna Low Viscosity (LV) Lubricant has the characteristics to be durable reliable and keep rotation silent.
