CBB-AL-103 Bottom Bracket JIS - 68 x 103mm

This bottom bracket features a standard JIS square taper that fits Sugino Messenger arms perfectly. It comes with lightweight aluminum cups, retainers, lockrings, a CrMo spindle, and a shield (bolts not included). Here are the tech specs: the spindle interface is JIS square, the shell is BSA with an ID of 33.6mmx24tpi, the width is 68mm, and the spindle length is 103mm.

Using this bottom bracket is quite easy. First, make sure your bike's frame is compatible with the BSA shell and the 68mm width. Then, carefully install the lightweight aluminum cups, retainers, and lockrings onto the frame. Insert the CrMo spindle and attach the shield. Remember, the bolts are not included, so you'll need to use your own. When using your bike, avoid riding through deep water or mud as it may damage the bottom bracket. For maintenance, clean the bottom bracket regularly with a soft cloth and a mild cleaner. Check the tightness of the components every few rides to ensure a smooth and safe cycling experience.
