iv have fixed a new transmission for my forthcoming winter tour of india.
my question is does it pay to change the chain after a while

i have fitted a new front chain wheel,back caset,and chain in preperation for my winter tour of "cycling paradise" india.
my usual practice is to to ride untill the chain starts slipping, then replace with a new chain wheel,caset, and chain.my question is does it help to change the chain before it streches to much?or is it a waste of time and money.i know how to test it for streching,by pinching the front.

Put simply, yes. About every 2000 miles, depending on how well you lubricate it.

In about 4 seconds I'll get flamed by someone who gets 7000 miles from a chain....

If you change a chain at 2000 miles, be prepared to change the cassette too - it might well have formed a unique partnership with the chain and sworn to forsake all others by that time.
I'm assuming that your new transmission is some sort of deraillleur.

Flamed? Who are you talking about?

2000 miles is a bit soon ......

Seriously though, a tour of India will be a bit harsh on a chain. Keep it well oiled, even daily, and you should be ok for 3 or even 4 thousand. Cassettes should last longer.

Take a couple of spare chains and a spare cassette.

I got through a Shimano chain in 1300 miles. It was very well oiled but never cleaned.
If you are going to cities on route you could post chains and other goodies to yourself 'Post Restante' at major post offices and collect them as you pass.

Thats the trouble with oil - it's sticky.

Muck and grit sticks to it and wears out the pins and hinges.

Use a non-sticky lubricant.

You may pay more for a proper chain lub, but if you're away in the "far flung", reliability and longevity are more important than cheap and cheerful.

Not with Indian customs you won't. I'd take a spare chain, and expect to have to replace the cassette at the end as well. As everyone has said, it's a harsh environment.

Hub gear and one of these

would be my answer.
Just fitted one and it seems to have negligible drag.
