Peloton Bottom Brackets

Smooth Revolution: Peloton® Replacement Bottom Bracket Assembly

Eliminate thumping, clicking, and resistance with a high-performance Peloton® Compatible Bottom Bracket. As the mechanical heart of your drivetrain, the bottom bracket houses the bearings that allow your crank arms to rotate. Over thousands of miles, sweat infiltration and high-torque "out-of-the-saddle" climbs can wear down the internal ball bearings, leading to a gritty pedaling sensation or audible "knocking" that resonates through the frame.

Our replacement bottom brackets are engineered to meet or exceed the original factory specifications for the Peloton® Original Bike. Featuring an ISIS Drive spindle interface and high-grade sealed cartridge bearings, this assembly provides a smooth, whisper-quiet rotation that restores your bike’s "library-quiet" reputation. The dual-sealed design offers superior protection against moisture and dust, ensuring your energy is transferred efficiently into every watt on the screen.

Symptoms of a Failing Bottom Bracket

• Audible Noises: A persistent clicking, ticking, or thumping sound that occurs at the same point in every pedal stroke.

• Mechanical Play: Feeling a "wobble" or side-to-side movement in the crank arms when you apply lateral pressure.

• Gritty Sensation: A rough or "sandy" feeling felt through your shoes while pedaling, even at low resistance.

• Increased Drag: The cranks feel stiff or difficult to turn even when the resistance knob is fully loosened.

Technical Specifications & Installation

• Interface Type: ISIS Drive (Splined) spindle for maximum torque transfer and zero-slip crank arm connection.

• Bearing Type: Dual-sealed industrial cartridge bearings for maintenance-free longevity.

• Shell Compatibility: Designed specifically for the threaded bottom bracket shell of the Original Peloton® Bike.

• Required Tools: Installation typically requires an ISIS Drive Bottom Bracket Tool, a crank puller, and an 8mm Allen wrench.

Pro-Tip: The right-side (drive side) of the Peloton® bottom bracket is reverse-threaded. You must turn it clockwise to loosen and counter-clockwise to tighten. Applying a small amount of anti-seize or waterproof grease to the threads during installation will prevent future "creaking" and make subsequent replacements much easier.
