These are our outboard bottom bracket center sleeves which can be used to change the spacing of your current outboard bottom bracket. They are available in 3 sizes to accommodate the following spacings: 68/73 mm (33 grams), 83 mm (38 grams), and 100 mm (46 grams). Each center sleeve is anodized for corrosion protection and comes with three o-rings pre-installed to help create a seal with your outboard bottom bracket cups when installed.
 
Please note that this will not work with our 1st Generation Outboard Bottom Bracket cup sets.
