Am I missing something here or is this plausible?
Ignoring the fact I was previously talking about a 44mm headtube.
If using an IS42 top headset bearing with a tapered steerer, 1 1/8" at the top bearing, could one use an IS42 top headset bearing intended for a 1 1/4" steerer such that come on Canyons and others. Then use a split shim to reduce this down to 1 1/8" and sneak a single di2 wire down the split in the shim which could be opened up a little/filed if necessary.
This FSA 1 1/4" headset uses a larger ID bearing than the steerer already and uses a split ring to compress the angular contact bearings so in lining up the split with a reducer shim split too, it would give me 2.1mm by my calculations, enough for a di2 wire
Am I missing something/being stupid (probably)?
