BB compatibility
By Noam

Hi there. My frame currently has this bottom bracket: Shimano BB-RS500-PB86.
I don’t know/can’t measure the width of the BB cage.
Will this eccentric BB fit in my frame? Thanks

This is not compatible with your current bottom bracket or any other road bottom bracket, you will need to use a mountain bike with unit designed for a 73mm shell. SK 18/07/24

Schlumpf drive compatibility

Hi there,
Can this be used with a schlumpf drive? I realise the schlumpf requires the BB shell to be milled at a 45 degree angle - will this render the EBB unusable once fitted into a bike?
