G3 Ceramic Balls
G3-grade perfectly round ceramic balls create lower rotational resistance, allowing your power to convert better to speed.

Technology
21 technologies across bearings, pulleys, and bottom bracket fitment — the reasons a TRiPEAK part costs what it does. Every image carries its own measured figures; click any of them to read the numbers.
Bearings
Ball grade, race finish, seal and lubricant are the four things that decide how a bearing rolls and how long it lasts.
G5 Ceramic Balls
The ceramic bearings of the TRiPEAK C-Series use G5-grade ceramic balls paired with a precisely machined steel race, delivering excellent rotational performance.
TRiPEAK C-Series
P05 Steel Balls
The TRiPEAK S-Series uses P05 precision steel ball bearings for reassuringly high smoothness and durability — 0.005 mm eccentricity.
TRiPEAK S-Series
MAX Balls
For high-strength structures such as suspension frame pivots, the MAX series is equipped with a full complement of steel balls for very high durability and impact resistance.
MAX bearings
NC Race
ROC Technology bearings carry a nano coating on the inner and outer races. This dry film cuts the coefficient of friction to as low as 0.03 dynamic.
JetStream Pro series
Oxide Coating
A black oxide coating on the inner and outer races improves the weather resistance of headset bearings and extends their service life.
Headset bearings
ZERO Contact Seal
A non-contact bearing seal that covers completely without adding rotational resistance — the optimal balance between efficiency and protection.
JetStream Pro series
Dura Tech
The outer race of the JetStream Pro Dura Tech headset is Teflon composite, eliminating metal corrosion and extending service life.

SUPRA LV Fluid
A low-viscosity lubricant for ceramic pulley bearings, with high flow characteristics for a fast, smooth-running environment.
Pulley bearings
ETERNA LV Fluid
Where SUPRA LV targets pure pulley performance, ETERNA LV is chosen for ceramic bottom bracket bearings, which carry load as well as speed.

JetStream Pro
JetStream Pro stands for Rotation Optimized Ceramic technologies — it takes more than ceramic balls to cut friction and gain watts.

Pulleys & cages
An oversized pulley only helps if the frame around it holds alignment. These are the parts that make 18T work on a stock derailleur.
18T Oversize Pulley
The 18T tension pulley design results in smoother chain movement. Compared with original 11T derailleur pulleys it reduces chain deflection angles.
AOPW pulley systems
Asymmetric Design
TRiPEAK's patented asymmetric pulley frame lets the tension pulley grow to 18 teeth while still fitting the original derailleur arm — maximum efficiency from minimal change.
AOPW pulley systems
Hollow Frame
The hollow pulley frame allows a much larger bearing, giving superior rotation and stable support for the 18T pulley while keeping contamination out.
AOPW pulley systems
Composite Injection Molding
Unlike traditional press-fit bearing pulleys, TRiPEAK's injection-molded pulley fully encases its bearing for a zero-tolerance fit.
Pulley wheels
Narrow-Wide Tooth
The narrow-wide tooth profile lets the pulley engage the chain more closely, significantly improving operational stability.
Pulley wheels
Aero Cover
An aerodynamic cover wraps the wind-facing side of the derailleur cage for superior aerodynamic efficiency, and detaches for servicing.
Aero-Wing cage kits
Bottom bracket fitment
Most bottom bracket complaints are fit complaints. These address the shell, not the bearing.
3-in-1 Core System
One bottom bracket set accommodates three different crank spindle specifications, so you can switch cranks without replacing the whole BB.
Thread and press-fit bottom brackets
Twist-Fit
Twist-Fit suits press-fit frames, making installation and removal easier. Dual-sided locking improves precision and holding force.
Press-fit bottom brackets
Snug Fit
A patented plastic-steel bushing prevents wear on the frame's bottom bracket shell — a real relief for press-fit frame owners.
Press-fit bottom brackets
The BB Tool
Compatible with the universal 44 mm O.D. bottom bracket tool, so there is no need to stock a drawer of specialised tools.
