arikira:
hi everyone,
im trying to sarch the web for oonfo regarding touring with the dyno hub.
ive found only few reports which are not quite informative as to how durable those hubs are over few years period.
the only three years warranty also "lights" a bulb...
does anyone here have more interesting info?
cheers,
arik

As far as I know  the service interval for the cartridge bearings is 50,000 km.
The number of years between needing service would thus reflect how far you cycle each year.

I tour with mine and it performs well, no obvious drag or problems. Not sure how it copes with total immersion in rivers etc.
Using a modern light system like Supernova E3 Pro front and rear lights gives an always available excellent light for not much weight.

Note that any increase in weight is offset by the lighter weight of your wallet!

My current lights setup includes a small lead acid battery and two 10 watt headlamps - this gives lots of light and only cost ~£30  but it is very heavy and I have a habit of forgetting to charge the lead acid.   For the last few years I've been hankering after a SON Dynohub but I can never quite get myself to part with the cash. (I am sure Ebenezer is my distant uncle)

Maybe I will treat myself this year.  I have done a fair amount of research on the hub and have yet to find any negative comments on the web  other than the cost  As far as I can make out it is a fit and forget component - it doesn't break down and doesn't require any special care.  In short it should be perfect for long tours.  NB The warranty period is now 5 years - see http://www.nabendynamo.de/service/pdf/Service_SON_e.pdf

Mine is still going strong at 29,000km of touring and commuting, I think it is great.

These guys took one on a tour from UK to Australia.

After 22,000km it was starting to play up and so had it replaced (under warrantee)

Maybe they had some bad luck, I am getting better mileage out of mine but my bike is un-laden most of the time.  However it seems like they had some time to deal with the problem instead of a catastrophic failure.

After bragging about my front hub I have just noticed a slight movement in the right (connector) side of my SON28.  Looks like I’ll need to send it off to the local Schmidt distributor to have the bearings replaced.
