Schlumpf drive compatibility
09 Nov 2020
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.
