Hub Dynamos in Australia

[Tim]

Looking at the exploded diagram wandering if only having the single set of bearings is a disadvantage. Also wandering if it is the reason any time I stand and ride (to get over a hill) I get disc rotor rub.

I thought the same thing when I looked at the diagram for my Shimano Dynohub. After a bit of research I found out there are in fact two sets of bearings like a normal hub. Its just that Shimano don't consider them user serviceable hence no inclusion on the exploded diagram. They are serviceable but a fairly fiddly and delicate job. There is a soldered on wire that runs in a groove along the axle that exits at the plastic connector. Apparently it is easy to break the soldered connection when opening the drive side bearings up and render the whole unit kapput.

If I get the Supernova I will have a Shimano, a SON and Supernova dynamos so a chance to do a bit of comparison

Andrew, I'll be interested to see the results over time. My Shimano dynamo is doing well but its still quite new.

thanks for the info, in case I decide to do some servicing. Hoping I have no reason to pull it apart for a very long time though.

For those interested, this eBay seller was recommended in a thread over at MTBR. The seller has a 700c rim with a Sanyo dynamo going for US$85. Nice price to get into dynamo lightening.

Geez, I was worried that we'd miss your famous 1% contribution while you were travelling. I have SON, SRAM, Shimano and about to try one of those SP hubs if you want a bit of cross-testing.
More to the point I've just built up a spare 700C front wheel with the SRAM dynamo hub, wired this to a B+M Cyo senso headlight and B+M Seculite taillight. The headlight is McGyvered to a spare bracket that NiteRider sells for the Minewt lights, easily wraps around a handlebar and clamped with those rubber o-ring bands (http://www.chainreactioncycles.com/Models.aspx?ModelID=30100). The taillight I did something similar but had to actually machine and attack with a file a small block of aluminium to make an adaption of the NiteRider mount, used the other spare rubber o-ring from the NiteRider kit, have this set to mount on seatstays or rack. Basically I can move this across to other bikes, such as when I want to use my roadracer for an Audax, or loan it to a friend pre-wired. Under $200 cost easily.
Lots of people I know say they might try a dynamo light setup one day, here's an easy way to try it out. It only takes a minute to install.

Edit: Supernova actually makes an o-ring handlebar mount that would work, might be suitable for McGyvering for a taillight as well, for about $18 each plus postage. I'm not that classy. http://www.roseversand.com/product/detail/aid:489133

Differently interested in your feedback on the various hubs. I was just looking at those Shutter Precision (SP) hubs last night. Is the Supernova one an actual SP hub? The price on the SP hubs is quite friendly

Hi Andrew,
(Hope your mending so you can soon return to your dream tour )
Because of Sons 5 year warranty, I'm yet to be convinced of the economics of buying
"any" model hub that may be half the price but less than half the warranty.
Although I certainly understand the attraction of handing out less "folding".

I understand where you are coming from but for my 26" build, the dynamo is not going to get a huge amount of usage so I will really not get the value of the SON five year warranty. For the commuter that is a different matter and I will now rethink my choice there.

Doing a bit more research and it seems that http://www.klite.com.au/ are the distributors in Australia for SP dynamos. Going by a June 2012 posting on their Facebook page they are selling the SP PD-8 for US$130 which is very competitive with the eBay price.

Also for those interested ... there are a couple of test videos comparing an SP dynamo with a SON dynamo.

Thanks for the help earlier


I'm going to go for a SonDeluxe hub in an effort to buy right the first time.


A couple of questions though before I "lock it in Eddy"


I'm going to use it on my Oppy Road Bike but should I go for the disc version so I can migrate it to future builds? (Tout Terrain frame = )


Second question - I don't roll with panniers. However I like the look of some of the B&M rear lights made for panniers. I should imagine that a mount could be made to rig one up say under the seat. Anything wrong with this train of thought? Should I just go with the B&M Seculite Plus?

Not 100% certain on this but have seen this approach suggested elsewhere so guess it is okay. I assume all it means is you are carrying is a little more weight given the need for the disc mount. The wheel spacings are the same no?.

I assume you are referring to racks and not panniers I can only comment from the perspective of my Busch and Muller Toplight Line Plus and as you can see in the photo is only designed for rack mounting. I suspect you would have a bit of work to come up with a means of mounting it on the seat post. I also assume the rack only mount Busch and Muller lights are of a similar design to the Toplight in terms of the mount.

b] though before I "lock it in Eddy"

Dynamo hubs are great.
Have you considered the new Son28?
I use a Sondelux but I have 20" wheels which the hub was originally designed for.
The Sondelux will be fine for bigger wheels with a led headlight but the output "may" not be enough to utilise an E-Werk (completely) or similar due to the wheels rotating slower than originally designed for.
I mention this as you may not want to charge a gps, cell phone etc. at the moment but perhaps
you may change your mind down the track.
Just a thought.

[KonaCommuter]

I was thinking that this would work to mount it under the seat (like the saddle bag) (Picture from Peter White Cycles)

[high_tea]

That's much nicer than what I've done, which was bolt about three different battery light mounts together. Might have to get me one...

[Aushiker]

Wasn't aware of those. Could work. I guess depends on your saddle.

BTW I agree with Rifraf. I would go the Son28.

Seculite Plus is a slightly older model of tail-light, just a single (but bright) LED, 1W if I recall. It is a very neat set up if you want to run a tail-light but not pannier rack. Just fits neatly to the mudguards - I taped the double-pole cable inside the mudguard with 1" gaffer tape.

Another option is the Spanninga Pixeo Xs which can be mounted on a seatpost or a mudguard.

Or Supernova E3 pro light with rear E3 lights than can be put on rack or on seatpost.

Very expensive but. BTW can the rear E3 be used with other front lights?

If the light at front can feed it 6V DC then yep it should be ok

Thanks Gents

I've redone my wish list and I'm close to placing the order



Those E3 tail lights don't strike me as being visible from the side of the bike. Happy to be wrong

Not many battery lights do either. Mars 4.0. I've never seen the E3 tail light in action but I've been told it's crazy bright.

[RonK]

Yes, quite so. I'm not impressed with mine - side visibility is poor, and I don't think a steady light is as noticeable as a flashing light. I'm not sure it is so bright either, but of course cannot see while I'm moving. It's definitely not particularly bright while stopped at intersections, and could easily be lost in the background. I mounted a Cateye TL-LD 1100 as well which is much brighter, flashes, and has side-facing LED's.
I suggest you save having the wiring clutter on the frame and use a battery powered flashing taillight like the TL-LD 1100.

I'll second this opinion as its the route I took.
I do keep a spare set of batteries in my saddlebag but I've not been caught short yet.

This has been bugging me too, I really can't tell how bright they are because you have to be moving. They are extraordinarily small so this is why I have doubts on brightness. I'll have to get the missus to drive behind me with a video cam, sounds silly but I just want see it myself.
