Question Hub Dynamos: Questions about tire/rim compatibility

Hello Everyone,

I'm new to the dynamo world, thus far it seems there are two major manufacturers including shimano and schmidt. I have also noticed that bike stores in my area do not stock or even list them. After looking at peter white cycles there seem to be several schmidt models available but I am looking for a hub specifically for my Felt F85 road bike which has the slimmer 700c tires. Should I expect to need a new rim for the schmidt hub or can I use the hub with the stock rim of the F85? Will any schmidt model work with the felt F85 or is there a specific hub I should be looking at?

The dynamo generator will be used at first as a power supply for my college graduation project and afterwards for a night lighting system. My understanding is the hubs provide 6v 3w once you are up to speed which will be sufficient for my purposes.

You will want to get a new wheel built around the hub. I got a Schmidt SON28 hub and a Mavic OP rim (32 hole) from Peter, and it seems to be well built. I have about 2,000m on it with no problems. The hub seems very nice, and it works well (as it should for the price). There isn't a lot of competition for these, and I never could find one cheaper anywhere else.

The price is what it is I happen to have a slightly older Nexus version and love it. I bought the whole bike for $180 (2003 Staiger Florida) I think any of the QR hubs should work on your Felt. I have used the old Sturmey Archer Dyno hubs for years, but they had a problem with over voltage and blowing bulbs at higher speeds. If you are going to build your own wheel you could reuse your existing rim. But I don't know of too many wheel builders that will do that. And yes most generator hubs are 6v 3w at full power. IIRC Schmidt does make a 12 volt but not sure it is available in the US.

Webshots is bailing out, if you find any of my posts with corrupt picture files and want to see them corrected please let me know. :(
