Have you got a link for those £100 son hubs? I can't find any on SJSC's website.

Yep!

NOTE: ALL SON DELUX SL MODELS!

A bargain if someone has an SL rim brake fork.  I suspect that's going to be very few people.

Thanks Dan 🙂👍

Ah, you're right PH, they're of no use to me 🙁

I'd probably do most of what's been suggested, I can't think of anything additional. I suspect if you did absolutely nothing it'd be fine for a year or two.  I like being cautious with such things, but wouldn't be beating myself up if I didn't get round to it all.   

But, has anyone paired a supernova with a B&M rear light? I like their brake stop tech and the built in reflector. I can't see that receiving a DC supply rather than AC is going to be a problem for the internal electronics and suspect the advice is more about selling more kit rather than a real problem.

I thought about it when my rear Supernove light went the same way, but Peter White who is my guru for all things dynamo says it won't work.  You lose the standlight, the light flickers, then is likely to go pop.

It is my understanding that the way that the B&M brake light works is by sensing the slower frequency of the AC circuit as you slow down.

I think that the Supernova sends DC to the taillight, thus not AC, so electronics that are sensing the frequency of AC are not going to work so well.  And I think that there is no standlight in the Supernova taillights, the standlight capacitor is in the headlight.

If I am right, a B&M taillight would work and the standlight would work too, but the brake light won't.

Everything I wrote above is based on memory, I can't cite a reference for any of that.  I have never used a Supernova.  If you have a multimeter, you should be able to measure if the circuit to the taillight is AC or DC.  If it is AC, then maybe the brake light would work?

I have only used AXA and B&M headlights.  And those have worked with B&M, Spaninga, and XLC taillights.
