Dynamo hubs

Drill through the mount, thread it and pop in a grub screw

Yeah, what he said^

I have a SON 28 hub which has lived outside for 4 years and had a daily rattle down various tow paths- the bearings expired and I was cursing myself for buying it through a German eBay shop for the sake of saving £20.
I got in touch with SJS who said so long as I had my receipt they'd send it back for warranty. They did and 2.5 weeks later I had a fully serviced hub back in my hands for the price of what it cost to send it to SJS.

Without a receipt and regardless of age the cost is capped at about £60 or something like that. I think this is very reasonable and a great service that you'd not get with other manufacturers.

I say this for anyone that is on the fence with which brand to buy.

Is a suitable cable for dynamos/lights available in most electrical shops and if so, what am I looking for in terms of rating etc? Thanks

Edit, it looks pretty standard so I will just get some generic wire 0.75mm dual core wire unless someone suggests differently.

I'm not sure but I don't think it's something most electric shops carry, you'd need to see a 12v specialist, like a car/camper/boat electrical supplier?

SJS sell it by the meter, you could try Bikefix in town?
I tried to get a length from Condor once but wasn't special enough for them to sell it to me.

I used this, 0.5mm is ample, it’s nice durable cable though, had it taped to my frame for a year and it hasn’t got a mark on it, and cheap.

No connection to the seller but this seems like a bargain to me. I've no use for something with such low spoke count.

Edit: potential issues with this low number spoke count (see below). Do your research.

EDIT 2: Auction is gone (link went to something else). It was a 24 hole SP Dynamo.

weren't they the ones that had a problem with stability or something given the low number of spokes?

I'd not heard that.

I'll update my comment.

I’ve offered £35 🤭

You get it? Bargain!

What sort of problems happen? I've recently built a 24h SON hub, but ran out of tubeless tape and haven't fitted it to anything yet

Haha indeed. No QR fork for it to go in like but I’ll figure something out

I'm looking at getting my first dynamo wheels built up.

Is SP SV-9 a better choice than the SV-8?

And is there any reason to not get Kinlin XR31 rims?

Thanks in advance

any reason to not get Kinlin XR31 rims?

I've used these for the last few years of ultra racing. The only problem I've had was a car driving into the back of me and destroying the wheel but I think you'll agree that's unlikely to be the wheel's fault...

was it wearing hi viz?

The bike was and the two rear lights were working quite well.

Amazing though that none of this matters if the driver is looking at their phone...

did they get 6 points on their licence or nothing but a slapped wrist?

Some kind of driver education course, ie. slapped wrist.

"Step 1, when driving, look out the fucking window"

The front one preferably

I mean, any window, would be an improvement.

Maybe asking too much.

Possible compromise...

ha!

Recommendations for small battery pack to use as cache battery? I’ve got a sinewave revolution wired to an SP hub, but the 6700mah Ravpower battery pack I have ain’t charging properly. The setup charges my phone absolutely fine (25% to full in 2 hours) but it’s getting nowhere with the battery pack. The sinewave unit does seem to heat up more charging the battery pack than the phone, not sure what’s going on.

I have some stock Arkose wheels that I'm not using, WTB ST i21 rims. Thinking of getting the SP PL-8 and lacing it on myself. Any concerns or suggestions?

Get a son if you can
