No IQ cyo premium or iq-x in the running?

The sp hubs that St kilda have are prebuilt wheels with Alex rims from the wholesaler.

I know this is to late for you but if anyone else is interested, Kerry at http://Klite.com.au" onclick="window.open(this.href);return false; is the Australian distributor for SP dynamos. He has the PD-8 listed at $135.00.

This one, because it has some basic data logging, can count mAH.

Wasn't getting much straight from the outlet on our Luxxos 50s, they're only rated for 500mA which doesn't go far in this smart phone world... 75euros from Bike24 or Bike Discount. Plus a couple of USB power meters from Ebay to keep an eye on what's actually going in and out.

Took mine off the bike for a while. Put it back on and now it won't work. Go figure. Seems to engage then disengage. Support wasn't helpful

Last bottle dynamo equipped bike I tried riding felt like the brakes were on.
They offer some serious resistance.

Consider keeping saving and get a dynohub.

If its just lights you want, you should be able to pick up a cheap vintage Sturmey Archer GH6 dynohub for not much which in my opinion would run rings around most bottle dynamos and have almost no drag.

My GH-6 ran my Edelux for quite a while until I had the funds to get a Son28 built up.

870g

Whilst it's cheap, that's double the weight of the Shutter precision ones, but multiples cheaper !!

At about 14.5 kph (~9 mph)you hit 2 watts. They sell 3 different output models and this is the middle one (Trekking). They sell a higher output unit that has higher wattage at lower speeds if you need it. I like this one because it has ample power in the ranges I ride in. If it had higher output I'd be putting in more of my own power and wasting the output. The other great thing is that when you are not using it there is zero drag (unlike hubs which always add slight drag).

I know this not for everyone, but I personally am pretty happy with it. It is on the pricey side, but that is not such a big deal to me as I am willing to pay for something that really solves a problem for me the way I like it.

I had a lot of opportunity for wet weather riding this spring and I can say with certainty that it has zero slippage problem in wet weather. It really is ideal for LED lighting. All of the other dynos on the market are older technology based on higher drain pre LED lighting. (All of the dyno models out there are basically unchanged for the past decade, and have not updated to optimize for the lower power needs of LED lights.)

I'll have to say that the mounting system is a bit crude, but once you have it set it is very solid and dependable. The only caution is that this is not for riding in mud that can get up to your rims. If that happens you are going to have some trouble with it working properly. I ride roads and crushed gravel and this has never skipped a beat.
