Theyre £30. Pretty good price and a decent enough hub imo

Rip to the decathlon 26er full dynamo wheels for like 40

They were £30 🙈.

I have one, currently in service on my son’s bike. Wish I’d got a couple more

715 grams

fucking hell

Anyone want an unused/barely used (I set it up but don't think I actually rode anywhere with it!) B&M Lumotec IQ-XS in black for £30?

Yes please! Will PM

The 3N70 and 3N71 tended to crack their cones early (too thin) while the 3N80 worked like a dream for ages. I don’t know whether the 2N70 used the same cone design as the 3N70.

Looks like they might do, differentiated by wattage output

Make sure the cone adjustment is correct. Excessive preload won’t be a good idea.

Should the connector on an Sp hub “snap” in or is it supposed to be a bit loose? Rode off-road with mine over the weekend for the first time and it came undone over bumps. It’s dual wired between supernova lights and a usb charger which may have made the connectors a bit bigger.

It snaps on tighter than the Shimano one, or at least mine does.

What stops the connector on an SP hub from spinning freely with the wheel? Mine rotates around the axle when moved by hand, and yesterday turned with the wheel somehow while riding, snapping the connecting wires and making my whole lighting/charging system useless mid-tour. Should the tightness of the QR keep it in place?

Should the tightness of the QR keep it in place?

Yes

Completely in place or just a little movement? My issue with my SP connector might be down to the same issue @ginllfixit is having as it seems to turn slightly then be "held" by the connector. That said, it's a thru axle so not sure how much more I can do to tighten it.

Completely in place.
I've got a thru axle one, it stays put

Locked tight. I’ve got a QR one and it doesn’t budge.

Something else must be amiss

I'll give it an extra hard twist then

Tightened a bit more, both problems fixed.

Thank you - seems like QR was much looser than thought so have tightened and will remember to do so in future

snapping the connecting wires and making my whole lighting/charging system useless mid-tour

Following on from this, I'm now home and trying to re-wire my setup and have completely hit a wall with it. Can't get either light or usb charger to draw power from the hub.

Had to snip the wire that had broken and assumed that would just fix it. Could there have been further damage done from this that isn't immediately obvious? Feel out of my depth and going away again next week so could really do with it working

Perfect hub for a shopper, just grabbed a few myself

Could the wire have been tugged up at the light end?

I’d try get as battery or a something on it to test the wiring as that’ll eliminate the hub/connection.

Connecting a battery wont help unless they are supernova lights. Most dynamo lights are AC
