Titanium cups designed for use with T47 'external type' BB shells of 68mm or 73mm width. Comes with reduced diameter internal sleeve to improve ease of internal cable routing. Equipped with low friction wiper seals to extend bearing life and a choice of bearing types. ‍ The cups feature a relief for easy removal of bearing when the time comes to change them ‍ It uses the same tool as centerlock lock-rings for installation. You will need to purchase a tool separately (I know this seems annoying but many of my customers have tools already as part of bike purchases and so this way avoids shipping redundant tools). ‍ They are available in the same range of colours as the bar end plugs and other titanium components. Please add a note to your order if you want anodizing
