Dynamo hubs

Default for SON hubs are some spade fittings at the end of the wires. Should be what you need: https://www.sjscycles.co.uk/son-hub-connections/

The Coax connector works very nicely with the adaptor block - you fit the adaptor block on the spade terminals on the hub, and the Coax connector fits into that. You can solder the Coax connector into place after you've run the wires through the fork. That's what I've done.

Moving from Dynamo Lights to Dynamo Hubs thread, as this:

...has been confirmed as a hub issue. No power output from hub (SP PV-8) after connecting to multimeter today. No obvious sign of damage either which is puzzling.

Guess the only option is to send back to manufacture for inspection/repair if possible?

I've had one do that, and they sorted it at Ison. It broke again almost immediately and I never bothered taking it up with them as I wasn't using the wheel, now its been in my shed for two years

Did they rebuild the wheel onto a new hub? Or just try and fix the issue

Afaik standard practice these days is to just take a new hub off the shelf and send that to you in exchange for the broken one. Assuming you have purchase receipts etc

I only sent the hub, and they swapped it for a refurbed one

pretty bad luck for the second one to break almost immediately :-/

yeah, just how it goes sometimes I guess. I'd moved on to a SON wheel and had put about 20,000km on that SP wheel anyway so figured I'd had my money's worth

My Son deluxe started making this squeaky noise but only when I sit on the bike, not when I just turn te wheel. Anyone got any idea? https://www.youtube.com/watch?v=wDnHG9WJayw

Does the SON coax adaptormajig work on a non SON hub?

It connects to 4mm spade connectors, as found on the SON hub but not on Shimano or SP hubs. But I have seen a Shimano to 4mm spade adapter, like in this picture:

It only fits the SON sized spades; I guess an adapter / diy adapter would work? Or use something like the dynasnaps?

Thanks for the heads up.

Got this back now. It was out of warranty but they offered to replace with a reconditioned hub for £30. What arrived looks brand new, no signs of use or even being laced to a rim.

Only problem now is finding a Velocity Cliffhanger 36h rim somewhere in the country...

Right, have a Shimano Nexus hub with the push on rectangular plug thing, which is running B+M lights
Question is, can I get a cable and some kind of step-up transformer to run a usb type charger type system running to power Garmins and the like (when not using the lights)?

uestion is, can I get a cable and some kind of step-up transformer to run a usb type charger type system running to power Garmins and the like (when not using the lights)?

Yes. Pick a dynamo hub>USB chargey thing, wire it in, job done.

Ah, neat, will have Searchy-Engine

Fuck me they’re expensive

Would this work?

There’s maths and graphs. Might take me a while to pick through as I’m stupid
But thank you :)

Yes, good find. Says it is suitable for hub dynamos on their website.

Ooh, well, it appeals to my cheapness / stinginess
Does it work?

Edit
I mean, for 30 notes, got to be worth a punt

I’ve got a cycle2charge top cap usb thingy that wasn’t very much many years ago. One thing to look out for is most newer tech is fussy with charging, and wants a stable current, tricky with stop/start/variable cycling speeds. Best bet is usually to charge a power bank (not fussy) to then charge your electrics

I have it and it's excellent. It's bulky, bulkier than you think. I use it with a pass through USB cache battery (only a small one)
