Just ordered a hub dynamo online
My poor ol' Sanyo Dynapower is getting a bit long in the tooth. The
bearings and bushes are wearing out. It makes a bit more noise than it used to, despite me lubricating the moving parts. I suspect it's days are numbered. So I ordered a PV-8 http://www.sp-dynamo.com/8seriesdynamo%20hub.html from the UK. Don't expect an Australian supplier to have something like this, or if it is available locally it's sure to be double the price! 90 GBP, minus VAT, plus shipping made it 86 GBP = 146 AUD. It seems to be reasonably light, has sealed bearings, and "class leading" efficiency and performance. I've also read that the vibrations are minimal. So when it arrives I'll order some spokes to build a wheel using one of my 2 Mavic OpenPro Ceramic rims - the one that's currently laced to the Mavic hub. The other is laced to a Miche hub, that I currently use every time I go for a ride. It'll become the daylight only spare wheel. The flange looks pretty beefy. I hope it can take a radial spoke pattern, so I can have a pair of front wheels with radial spokes. I just like the look, and provided the hub can handle it, see no need to cross the spokes. -- JS |

problem with output consistency, varies not with rpm but air moisture content,,,,;leading to failure after 3-4 variations.

Of course, you couldn't find a dealer with stock of the service kit, because a new Shimano hub dynamo of a newer design, completely built into a wheel with a quality rim and quality spokes, was available from the discounters for only about a third more than the service kit. The same was true of the hub gearboxes though I found one dealer (Petra Cycles in the UK) with stock of the service kit. Looking forward to your report on the Shutter Precision Hub Dynamo.

Dark season is coming here soon so I put my dynohub wheel in my recently Rohloff hubbed winterevening bike this weekend and was curious about the weight of that bike now with all that 'heavy' stuff so I hung in on a scale: http://lh3.googleusercontent.com/-BE...k/IMG_2177.JPG http://lh5.googleusercontent.com/-VI...k/IMG_2181.JPG I can live with that. -- Lou |

Apparently the PV-8 and friends have sealed cartridge bearings, that I would assume are replaceable. The only negative I read was that the axle is Al, and some people have broken them. I can only guess that these folks are heavy people, or carrying heavy gear perhaps. Being a relatively light rider and not one to crash through potholes and the like, I don't expect the axle to cause me grief, but I guess the proof will come after some years of use. BTW, I installed my headset, knowing the surfaces were already properly faced. I bought a huge bolt, two washers and a nut to suit. With a pair of spanners I have a headset bearing press. -- JS |

That's one of the problems with bike dynamos; it's hard to get one to last for 50 years. ;-) Something like that, but it's not been used for very many years. Where it was traditionally mounted (under and behind the BB) had it suffer all kinds of watery grit. So I ordered a PV-8 http://www.sp-dynamo.com/8seriesdynamo%20hub.html from the UK. Let us know how it does, please. Of course. If I can come up with what I consider a good combination of dynamo and light, I want to try to get some others to use them. I'd like to be able to buy the parts, build a wheel and sell a winter training lights solution to last through years of abuse. It's difficult now though with the cheap lights from the likes of DX - though the beam is not optimal and the batteries always need charging. Any ideas on how to apply a ceramic coating to an Al rim? From what I can tell, Mavic are the only people who really made it happen. Some others have tried, but have not been very successful, and now Mavic have gone away from the Ceramic coating they once had, presumably because the rim never wore out. I know they've got some new coating system now, but from what I've read it wears off after a year or two. My Ceramic coated rims are still like new after about 100,000km. -- JS |
