BB compatibility
By
17 Jul 2024
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
What is the thread size? Does this accept standard ISIS BB?

Hello, thank you for your enquiry.
The Thread is standard British thread measuring at 1.37 x 24tpi.
Hope this helps TC 21/0/24
Schlumpf drive compatibility
By

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?
Hello, weave no fitted a Schlumpf drive with this part and as such can not confirm compatibility.
