Touring - Shutter Precision Dynohub?

Anyone here use one of these models??

http://www.sp-dynamo.com/

I've been interested in the SONDelux for some time, but this seems a much less expensive equivalent. I can't find a place to buy it except ebay... anyone know a real dealer that sells these?

sorry no idea, but I challenge anyone to be able to read the Star Wars style blurb that flits by like a X-Wing fighter on double afterburner in their promo vid.

I have one, but I'm still working on the frame that it's going on so have zero miles on it. Seems like a quality item. There are a lot of options with the Schmidt. I'm not particularly happy that the flanges are so close together on the SP, but I'm sure it will work fine.

If you want to buy it from a dealer, you can buy a Supernova which apparently is the same hub with some different markings. It will cost you though.

but this seems a much less expensive equivalent.

much less but not equivalent, except both may have the same output..
6v3w..

Schmidt, German, is the lowest rolling resistance in the wheel
and has a sealed bearing on the axles..

the other is cutting corners to get the price down, and not German made.

Various here, Supernova (Not much less) [Taiwan made] and Shimano.. come across the Pacific.
German Schmidt comes across the Atlantic , to American Continent..

My SA XL-FDD didn't cost no arm + leg. I have 2800 miles on it, zero problems. It has nothing to adjust, no switches, sealed bearings. The power/lights are always on, fine with me. The brake pad is worn .4mm on one side ( by the cam which is normal). So I expect another 10,000 trouble free miles. Finicky rim/disc brakes ?? pffft
Hard to know how long the bearings will last.

I am still running a 40 year old Sturmey Archer dyno hub ;) it is pushing modern LED lights now. I also have a more modern SA as well as a couple of Shimanos. I know several people with the Schmidt, I have never seen the Supernova/SP model anywhere.

If you read Germany there is a discussion of a variety of dynamo hubs, including several

Well...., it's better than nothing.

It looks like the distance between the flanges is the same on both the SP and the Schmidt, as far as I can tell from their websites.

So who needs a dynohub with 20 spokes? Is that a 16" wheel or something. No 36H from sutter

Shutter Precision do do a 36h model (http://www.ebay.com.au/itm/SP-hub-dynamo-dynohub-PV-8-24-28-and-36h-most-efficient-and-lightest-/271076259419?pt=Cycling_Parts_Accessories&hash=item3f1d67765b#ht_1570wt_1180) now ...

To the OP, I suggest you take a read of Rob Dean's post (http://robdeanhove.blogspot.co.uk/2012/07/racing-on-dynamo-charging-my-gps-bright.html) for his thoughts on the SP dynamo he uses. Also you can get them via eBay (http://stores.ebay.com.au/Intelligent-Design-Cycles?_trksid=p4340.l2563). This is the seller that Rob used I believe.

A couple of other resources worth a read include Bicycle Components Review (http://swhs.home.xs4all.nl/fiets/tests/verlichting/index_en.html) and there is at least one owner active in the Australian Cycling Forums (http://www.bicycles.net.au/forums/viewtopic.php?f=9&t=41022) [link to the thread on dynamos].

I am going to build dynamo wheel for my commuter for next winter at the SP is on my short list. It will be a toss-up between an SP and a second SON 28 for me I suspect.

Various here, Supernova (Not much less) [Taiwan made]
Supernova is a Shutter Precision dynamo going by all accounts. I also believe Velo Orange where at one stage selling a rebadged SP dynamo as well.

Thank you all, for the advice. I did order the SP Dyno a few days ago, along with the rest of the wheel. Once everything comes in (might take a few weeks), I'll be building the wheel. We'll see how it goes!

If you go to Peter White's site you will find a good dyno for about $50. His comments on it are positive and he can build it up for you if you want.

If you need a dyno but aren't into the cost of a new dyno based wheel, you could try the SunUp DS1-R that is on ebay for $125. It looks promising so I ordered one this week to examine/tryout. It fits over the rear axle on the left side and has the same volts and watts as the typical front wheel dyno. When it gets here and I have tested and examined it, I will post a report with pix and data over in the lighting forum and leave a breadcrumb in the other forums.

Do the SP and/or Supernova hubs use the same connectors as Shimano? I`m wondering if I could use the same light with one of those low output hubs as I use with the Shimano hubs I already have. It they have different connections though, I`d rather just keep them all the same than take chances swapping the already fragile plug back and forth.

the SP connector snaps onto a Shimano dynohub and works in a similar way. However, it uses the wire for the connection and doesn't have any metal in it. So it's not identical.

Thanks, Unterhausen. Not the same maybe, but the description you gave SOUNDS like the connection that the Shimanos use. You`re familiar with Shimano dynos? Which were you describing?

I tried the SP connector on a Shimano dynohub, and it worked. I also tried the Shimano connector on the SP, and it worked, but it was a bit tight and hard to get off. Probably ok though, the SP certainly lit up my headlight. I have 3 different Shimano dynohubs, all different, but they use the same connector

Ah, I think I`ve got in now. Thanks for the clarification!

From what I've read,the SP hubs are a different design inside from the Son and most of the others,

Son uses magnets that spin around a coil.....the SP has a coil that spins around a magnet.

Thus it is much cheaper to produce and that is why the price is lower than son,with the same 1/2% drag with the light off and as close as you can get to a son with lights on,without copying it directly.

That is the hub I'm going with if I can find a 24 hole version somewhere.(I want to drill it for 48 spokes.)If not I'll settle for 36 and use Alpine or Alpine III spoke.

I don't really understand how it could be cheaper to spin the windings, you'd need brushes. I saw pictures of it and it sure looks like they are spinning the magnets to me

I haven't seen a picture but one of the German sites,the "talking fingers" were saying it has a multi pole magnet(s) around the axle with the windings spinning around them......No? That's just what I've been reading.Do to this and that,it was much cheaper to produce.

I'd sure like to see a picture of the inside......and it ain't because I haven't been looking,my German is much better than it was a few weeks ago.

I tried to find it again, but failed. I'll post a link if I find it. Somebody's blog, actually

I found one in english finally,http://road.cc/content/review/65840-shutter-precision-pv8-dynamo-hub

Looks like it has some type of magnitized ring spinning around instead of separate magnets.....I REALLY misunderstood.....DOH!

I would like to see a picture if you ever find it.

So who needs a dynohub with 20 spokes? Is that a 16" wheel or something. No 36H from sutter

I'm getting the 20 spoke PV-8 model to use with 700C Velocity rims on a Cervélo R3 set up for brevets.

There are pictures of disassembled dynohubs in this blog post (http://fahrradzukunft.de/14/neue-nabendynamos-im-test/)
Text is in German, but the picture seems pretty clear
