Shimano 8 speed hub & dyno hub/roller brakes - any user info welcome

Can anyone who uses these tell me if there are any problems with
Shimano 8 speed gear and roller brake hub,shimano dynamo hub and
roller brake in long distance road use. Is the lowest gear low enough
for a 1 in 10 hill and are the brakes adequate for a similar gradient?
Are they ok for trailer towing? I am putting together a touring bike
for a 'round-Austrlia'trip of about 12 months duration and the load on
the bike and trailer is anticipated to be about about 150kg. Any
thoughts or ideas most welcome.
Thanks
Nick, Australia

presumably you are going the hubgear route for lower maintenance
yeah?
pro's and cons. weight. gear range is 'OK' but if you are hauling s
much stuff you are probably gonna want smaller than bigger.
Can you stretch to a Rohloff? pricey but lighter and better geared.
If you can get in contact with Alan Christie or someone form th
touring clubs (melbourne -MBTC - http://www.mbtc.org.au/ or simila
org if is not near you

I hope that 150kg includes your body weight..... & you're 'big boned'
Slow trip otherwise.

A BoB trailer handles fine with ~25kgs. I second the Rohloff ove
Shimano

The 8-speed hub gear has a 307% range. About the same as a mountain
bike or tourer's rear cassette. But you'll be stuck in one chainring,
so only have half the overall range.

Is the lowest gear low enough
for a 1 in 10 hill ... 150kg. Any

!!! Only if you have a ting chainring, and top speed of 25km/hr.
I'd want a very low gear to haul 150kg up 10% for any length of time.

thoughts or ideas most welcome.

Carry less. Reconsider conventional derailer gears, unless you can
afford the Rohloff.

good luck

The standard load that most tourers carry on a long bush tour is usually
around 40kg max. Friends of mine who rode the Gunbarrel Hwy from Uluru to
Wiluna (not for the family tourist) took an extra 30kgs of water and had to
limit other gear, but still wouldn't have exceeded 60kgs.

What unusual extras are you carrying that adds up to 150kg? A portable
generator?

150 kgs up 1 in 10 grades - good luck. Glad I'm not hauling it.

Cheers
Peter

I'd ring Adam at Cheeky Monkey in Sydney. They build 'city-bike' bikes
put together with the shimano hubs, and supposedly sell quite a few
Rolholfs. There's also a Sturmey-Archer(sp?/wrong?) 8 speed hub on
the market too.

What sort of trailer are you talking about ?

Don't forget some excellent brakes, stopping that lot down
a hill in the wet is going to require something serious.
I wouldn't want to rely on a hub brake only. What's a 1/10
hill as a percentage gradient anyway? (10%? I thought it was
more complicated than that). We once hit the wrong direction on
a 20% hill, luckily it was only short, but it took two of us
to push the bike with the kids in the trailer to the top.

Thanks for all the help so far. To clarify a few points......
I am 6ft 4in and weigh 100kg and the other 50kg is for the trailer and
load. I'm getting a custom frame made as I find conventional frames
too small for my height. Sounds like the Shimano gear hub doesn't have
a big enough range and the rohloff is the way to go.

I hope to have a trailer built out of light steel with 26inch wheels
and be able to slot in a large esky for a waterproof storage unit. I
have seen gooseneck trailers coming off the main frame behine/below
the seat, not off the rear 'axle'. They seem very manoueverable and
well-balanced.

Further thoughts????????????

50Kg throwing your bicycle about at the seat post doesn't sound too
controllable to me. I recently had a lot of trouble with 50kg getting a
wobble up on a bob style trailer. My suggestion is a two wheel trailer
with a gooseneck to near the bottom left axle, or a bob style connection
to both axles/rear dropouts.

Unless this is for a beer trailer, you might also like to look at
galvanised tradesman tool boxes.

I don't like the idea of a high mount trailer, but I 'spose the traile
bikes tow OK. They are single wheel like a BoB though.
A BoB trailer is rated to 32kg & I'm sure could carry a bit more o
good roads. Can you trim your load down
