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. Congratulations, you won't regret it. 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. A very pretty cycle. Is that a Litespeed ti cyclocross frame? And how did you arrange the chain tensioning? I can only think of an eccentric bottom bracket or good luck with chainstays just the right length. I count seven bicycles in the picture including the Litespeed though I might have got confused trying to count wheels. Are they all yours? If it's not too much trouble can you tell us something about them? PH |

In theory, that Dynapower is serviceable with a kit Shimano lists (or used to list) for the early Shimano hub dynamos, which were just the Dynapower in a new dress. 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. Shimano might have a service kit for theirs, but mine is a Sanyo roller dynamo. Completely different beast. http://www.flickr.com/photos/5510267...n/photostream/ -- JS |

Nice! Only thing I don't get along with is the flat bars. I haven't found them comfortable, but that's personal preference. Is there a rear brake? Not that I use rear brakes normally, but there are times when it's nice to be able to control your speed gently with the other hand. It's just getting lighter here, but I'll still need lights to ride after work for a while. I hope my old dynamo lasts this year out, while I build a replacement system in my spare time. -- JS |

Too distracting. Oh, "wrenches", sorry. So do you speak of open ended wrenches and ring wrenches? We'd say, "Can you hand me the 14/15 ring spanner, Mate?" This would of course refer to a ring spanner with a 14mm ring one end and a 15mm ring the other end. -- JS |

A box spanner is something completely different for us. It's like a tube with a hexagonal end and a hole transverse such that you can insert a pin or screwdriver shaft to apply torque. http://i.ebayimg.com/00/s/MTYwMFgxNjAw/z/mU0AAOxyf2pR5VaM/$(KGrHqFHJEIFH,op-+7vBR5V,L2w8g~~60_58.JPG The kind of thing you would use to take a water tap off to replace the washer(s). Some spark plugs may be removed with a box (or tube) spanner. -- JS. |

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. Entirely possible. It's - what? - probably over 30 years old. 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. What's old is new again? Not a ceramic coating but I still have an old "Matrix" (Trek) hard-anodized rim. I don't use it because the hub is shot and I couldn't find new parts to rebuild it (and the matching rear with Helicomatic was gone before I got the bike.) Seems to have been a not very successful idea... nate -- replace "roosters" with "cox" to reply. http://members.cox.net/njnagel |
