Facebook Twitter LinkedIn Pinterest Bluesky Threads Was hoping for some help identifying this bottom bracket off a Diamondback Haanjo 2. Need to replace the bearings. I'm assuming this is a cartridge unit? by Lucky_Marzipan_8032 Bicycling Bike Bike Repair Biking Cycling Repair

GenericName187 on December 18, 2024 1:38 am You need a 20 spline tool to remove the cartridge bottom bracket. Park Tool BBT-22 or BBT-32, or any other reputable brand will do. When you remove the bottom bracket hopefully the shell width (68 or 73 mm) and spindle length (between 103 and 127 mm, probably around 122.5 mm). The drive side cup is reverse threaded, you will turn clockwise to loosen. https://www.parktool.com/en-us/blog/repair-help/bottom-bracket-removal-installation-threaded https://www.parktool.com/en-us/blog/repair-help/bottom-bracket-tool-selection-threaded-and-thread-together
