I am about to buy a new chain for my Raven.
I will keep the old one and perhaps do a swop every so often to even out wear on the chains.
How do I mark the chain so that I know which way is which?
Am I correct in thinking the chains can be 'flipped' in the same way the front and rear drives can?

Matt,
if you have the right size chainring and rear sprocket invest in a chainglider.
This could then be the last new chain you need to buy…

Unless you have changed the gearing matt it was a 38/17 so could take a chainglider although I am not sure if the chainring is thin enough - you may need to change to a surly ring

OK. You've got me thinking about the glider.
But back to the chain question. How best t keep track of chain side/direction between swops?

And, no, Andy. I haven't changed rings. Although you kindly gave me a very large spare front one. With such a slack chain I thought it may be a handy swap. But too large, without adjusting the BB

I am really struggling with this one. Assuming Rohloff how and why will the chain last forever. I assume you are not including the chain wheel and sprocket? Next what is chainglider? Could you supply a link to a chainglider? Thanks SD

Sorted found a chainglider. Can I assume by keeping the chain clean reduce ware? And the same will apply to the sprocket/chainwheel? Is it noisy? How will changing chains regularly stop the chain wheel/sprocket waring out ignoring dirt? I am a fan of investing to save!
PS The following is straight forward bragging!!

In my experience the wear on a chain is mainly caused by dirt/grit/water thrown up by the wheels which sticks to the oil on the chain and making a very effective grinding paste. It also results in a lot of work trying to clean it all off and replacing components as they wear.
The other cause of wear is the chain shifting sideways in a derailleur setup.
Running a hub gear or single speed eliminates the chain shifting wear.
Enclosing the chain in a chain case keeps it clean and thus eliminates the main source of wear.
I would expect using a chaincase like the chainglider to make the transmission components last 4 times longer, but I have not had one long enough to prove this.
