I bought a Schlumf Speed Drive last year with the intention of fitting it to my Cannondale Alfine8. Unfortunately due to a lack of information at the time I have now found that it will only fit an externally clamped EBB shell. So as I can't use it as intended it is now for sale. Brand New, never fitted to a bike, 170 m cranks, 32 tooth chainring + trouser guard. A fantastic piece of enginneering. Some original paperwork included. Note, this is the EBB model and it fits directly into an externally clamped EBB shell (verified by email from Florian Schlumpf). I have a much older mountain drive on one of my bikes and it is a fantastic piece of kit so I'm verry sorry not to be able to use this one. More information and photos on request. Asking £300 + postage in UK, cheque or paypal. Located North Yorks, contact Eric 07724 121366.
