Dynamo Lights

no catch, good wheel, I have a cheaper version of that I bought on german Ebay. Works fine.

Talk of the B&M small rear light above. Brompton make a rear light bracket with 50mm spacing that fits to a brake bridge. I’ve popped one on this weekend and think it looks pretty neat. High enough to be seen above the rear wheel, low enough that you can make a saddle bag work too depending on frame size. Could potentially do with a light bit of bending to adjust to frame angle etc but seems one of the cheapest and easiest ways to get the job done.

I had Rose build me a custom Dynamo wheel a few years back.
It wasn't in the catalogue, but they ordered the parts in and built and shipped it to me for less money than I could buy the individual parts in the UK.
Unsurprisingly, if you phone them they speak perfect English and also respond to e-mails in English.

oh, damn, this is a good tip. ta!

I did not know that. I am filing that away for future reference. Thank you!

I bought the 700c version. Rim isn't great but I intend to use it before replacing. Unfortunately I've not used it yet (its summer) and just got an SP wheel. But it seemed like such a bargain it'd be daft not to have one in 'stock'. Will stick it on a beater or something one day.

Cheaper than the same hub on its own from lots of places.

Was it cheaper with postage?

My SP 6 bolt disc hub dyno has failed. I've tried testing it by putting a multimeter on the output and spinning the wheel..... nada.

Any recommendations for a replacement?

Alternatively, does anyone have a recommendation for a bottle dynamo?

Another SP or if you're feeling flush a SON.

Thought as much.

The Velogical rim dynamo looks fun but it's only 1.5W.

Pretty sure 1.5w is fine, even if running rear light.

Nope. 2.4w is ok, 1.5 probably not.

IIRC the nominal output is 1.5W, but they do a couple of different versions (sport, special, touring) that produce more or less power at real-world speeds; I think they've been successfully used on the TCR &c.

@mi7rennie I think you can get SP dynamos repaired in the UK now. I've got a link somewhere

Feb last year this was posted on CTC.

Might be worth contacting Ison

I will certainly try. It's the output that has failed on mine but got to be worth an email.

Have you tried turning it off and on again?

Sorry for the dredge but is there a manual on/off switc? So if i wanted to use it with a sinewave it wouldn't draw all of the power.

There is! Big button on the back of the light. I'm super happy with mine. Got it for £45 from bikediscount.de

Thanks @miro_o

what is the best method to secure the rear light cable inside SKS mudguard?

@amey Black gorilla/gaffa/duct tape. Srsly. That's what's on my PDW's. Has been #flawless
