Find the official TRiPEAK installation document for your bottom bracket, then match the tool to the part number. The links below come from TRiPEAK USA’s support library.
Choose the tool from the product specification
TRiPEAK’s technology page distinguishes Shimano Standard tool required from TRiPEAK TOOL REQUIRED. For the products currently listed here, BSA and ITA specify a 44 mm, 16-notch tool; the oversized units marked for the TRiPEAK tool specify 50 mm and 12 notches. The BB86 press-fit products use their own installation procedure. Check your exact part and manual before starting.
Open the matching official manual
Select the shell application and crank system shown on your product. The BB30/PF30 and BB86 DUB/ROTOR listings have more than one document because they cover distinct configurations. Scroll the table horizontally on a narrow screen to see every link.
Use the document for the assembly details
Follow the matching document for the adapter arrangement, spacer order and tightening procedure. Check that the crank rotates smoothly and that the installation is adjusted as instructed. The official support library also carries the other TRiPEAK bottom bracket and pulley manuals.
