OPERATING TOOLS

Bottom Bracket Installation

Use the included TRiPEAK ETERNA LV Fluid to Add a full lap of bearings. Rotate the bearings gently by hand to ensure the lubricant is evenly distributed.
Carefully press the seals back into place on the bearings, ensuring they are seated properly and securely. After reassembly, check to ensure the bearings move smoothly and without resistance.
Ensure that the internal cable routing of the frame will not interfere with the bottom bracket (BB) installation. Clean the inside of the BB shell on the frame, ensuring it is smooth and free of debris. Apply a thin layer of grease to the inner edges of the BB shell to assist with smooth BB installation.
Remove the drive-side BB, which will be installed later.
Gently position the non-drive side BB into the non-drive side of the BB shell. Using a dedicated BB installation tool, press the non-drive side BB into the BB shell of the frame until there is no gap between the BB and the frame.
During pressing, ensure the BB is inserted at a proper vertical angle to the frame. If you encounter excessive resistance while pressing, stop the process and recheck the insertion angle and the BB shell for any debris or deformation.
Align the drive-side BB along with the Snug Ring vertically with the inside of the drive-side BB shell on the frame, and rotate it counterclockwise to insert. Then, use the BB wrench (B015) to fit the drive-side BB, continuing to rotate counterclockwise to press it in. Tighten to a torque value of 30Nm, ensuring there is no gap between the BB and the frame’s BB shell, completing the BB installation.

If the non-drive side BB rotates along with the drive-side BB during installation, prepare another BB wrench (B015) to secure the non-drive side BB in place, ensuring the required torque value is reached.

Bottom Bracket Maintenance

For maintaining and servicing TRiPEAK bottom brackets, we strongly recommend hiring a trained bicycle mechanic at your local bike shop.
Regular maintenance is generally recommended after riding 5,000-10,000 km. If riding in harsh conditions (wet, dusty, extreme temperatures, etc.), it is advised to perform maintenance immediately after riding.
Avoid repeated disassembly and reassembly of the BB Cup unless necessary, as maintenance should only focus on the BB bearings to prevent damage to the frame.
Do not use high-pressure water jets to clean the BB to avoid water infiltration and bearing damage.

Regularly check the torque value of the BB Cup, and do not ride with a loose BB Cup.
