Thanks Tim. My laptop is small space wise but recharging seems like solar would be the only possible option.

Can anyone see a reason to go centre lock instead of ISO on the dynamo hub when running a Rohloff 4 bolt on the rear? For a travelling bike it seems CL would require an extra tool and since Rohloff have gone bolt on rear any reason to go CL on the front? The internet says CL is easier to remove/install but the rear rotor is bolt on anyway.

If you go six bolt, consider seriously some non ferrous bolts would be my suggestion.
My Rohloff four bolt disk attaching bolts are going rusty with extremely limited exposure to the elements.
I plan to replace mine with stainless steel and with a healthy dob of copper grease both on the Rohloff and Son28 dynohub.

Interesting you should say that because I ordered some titanium bolts to replace some rusted head stem bolts. Less than 12 months the original ones lasted what is it with manufacturers putting the cheapest bolts on their > $2K bikes must cost them 2cents a bolt OEM. Now I am trying to justify why I bought such an expensive set of replacement bolts. It better not rust, ever. Stainless would have been a better choice.

Never heard of copper grease cheers will look into that.

I purchase my stainless steel bolts etc from an eBay shop, fastenerkitsonline. Australian shop, all free postage. Found them quick and it seems reasonably priced. Can even place orders for two bolts etc.

Titanium should
not corrode
be lighter

Stainless would be cheaper .. but about the same weight as the old steel ones.

:o "Never Seize" is one brand name that I use. My choice is to either use Lock Tight or Never Seize. Metal to metal contact is asking for problems, especially dissimilar metals (exception - stainless steel on both sides can gall - leading to seizure). I find that when it comes to separate them either does a reasonable job. The only exception to that is an exhaust system that requires yearly replacement of the Never Seize.

Both things reduce the air, water and dirt out of the contact area.

Thanks Warin.

There's some interesting info on the S&S site about this.

http://www.sandsmachine.com/grease_t.htm towards the end has a list of many products tested.

Thanks, that's a huge selection of bolts.

I've found with my titanium frames that it very susceptible to galling using stainless steel bolts. I would not use ti bolts without proper lubrication.

Bolts Nuts Screws Online is a Gold Coast company that offers great service even for small quantities. Socket Head Cap Screws are the most commonly used on bikes.

Interesting S&S mentions this too on another page:

Threaded stainless steel and titanium fasteners have a tendency to gall when they rub against one another..... This phenomenon is especially common on threaded titanium parts.

Not sure if its been mentioned before and don't have enough spare time today to trawl back through all the pages.

Heres a link with some possible pertinent info for the photographers amongst us who are interested in charging camera batteries via cache batteries and solar.

Thanks for this.

Voltaic also have a range of camera battery cradles which could be possibly used.

They have a guide to setting up a charging station.

I really like my little Lenmar clip charger. It can charge straight off the ewerk or I can charge my $30 Arctic cache battery and then plug the clip into that. Simple, cheap it works.

This one from the manufacturer http://www.youtube.com/watch?v=IyjkTfUB ... detailpage

Thanks for the heads-up. Unfortunately my battery is 7.6v and the clip charger is way to small, however their other charges look promising charging up to 7.4v. Just depends how critical that .2v is.

BTW that video is shocking!

It was. I just pasted the first thing I saw. I saw the Lenmar one after.
