Taper? Yes. Looks fine with an extension here though, and extensions are being used successfully out in the field.http://images.ttcdn.co/media/i/product/ ... g?size=500
Any luck with this and any idea where i could source the extension? I have an s-works srm which i'd love to be able to use on my cervelo.
I've contacted Mattias Hellöre (he's the guy behind Experimental Prototype, which is also "Experimental" as a Tictail shop). No response.
The tictail shop for Experimental always seems to be in development... and I know how that goes, so I don't have any blame there, just empathy despite my need for an 11mm hirth extension.
I'll have to design one myself. If other people are interested I may then have to place a multi-order from a manufacturer... whomever that may be.
Prendrefeu, do you know how the hirth extension affects the chain line?
I remember a few years ago, someone machined a Cannondale spindle to fit Hollowgrams on a non-BB30 frame, and while it worked, the chainline was pretty screwy.
It shouldn't on BBright since the extension would basically push the NDS arm out. BBright has the width different on the NDS anyway, it's asymmetrical on the frame (hence BB"RIGHT")
Anyway, waiting for crank arms to arrive, need to tune those first, then make the extension.
any BBRight+BB30 bottom bracket would work. It looks like the Wheels MFG is the lightest in the 'threaded connection' version, but a person could also run a usual press-fit BBRIGHT/BB30 into the shell, subtract the spacer, and be around 50g.
