NEW SHIMANO DYNAMO HUB (?)
 

I saw this today:

Not much info, but it looks interesting. 100g heavier than a PD-8. It looks like the bearings are user-serviceable.

I don't know how you could even contemplate adding all that extra weight
to the front of your bicycle.

Not gratuitously with no cost savings or other benefit. That hub cost more than my SP PD-8. The apparent benefit is adjustable bearings, if it has them, and center-lock, if one prefers center-lock. I don't know about the internals.

Ever serviced a Shimano dynamo hub?

For cyclists who are considerably faster than jbeattie, buying three heavy,
lossy DH-3D37 hubs to get destructive practice with the wiring, and still
have one functioning spare looks like an alternative.

But he'd save more than two ounces ... compared to the pointless DH-T4000
that would "best" match his dim Luxos.

No. The bearing arrangement for the right side looks pretty simple. I don't know if the DH-T8000-3D has the same internals, though. The electronics in the schematic appear to be sealed.

I'm super fast.

I save a pound with my Urban 800. I'm not even running my dyno hub this time of year. I'll re-mount the mood light at the time change.
