My husband and I are doing some loaded touring this summer. His bike is an 8-speed triple; mine is a 9-speed triple (both Shimano). In the interest of saving weight in gear, I'd like to take along just a spare 9-speed chain. Can one run a 9-speed chain on an 8-speed cassette? Thanks for the help!

I've done a little loaded touring in my day. Nothing too serious, but I've covered some ground while carrying some weight.

How's this for a way of saving even more weight?

Rather than drag an extra chain around, why not pack a chaintool, bring a couple of extra links, and carry a few of the replacement pins (of both types)?

In the unlikely event of a chain failure, you should be able to make any necessary repair to keep you rolling.
Good idea, my thoughts exactly (nm)Chen2

That would certainly get you to the next town with a bike shop. Then, if you felt you had to, you could buy a whole chain.

A whole chain can't go bad all at once, as far as I can imagine. Only a link or two, possibly, could fail at once. Even without any extra links, you could remove one or two and keep going, possibly being unable to use a big ring big cog combination.

Of course, if your chain breaks, flys off the bike and down an embankment into a river, then you're stranded. :-)

I have jammed chains on MTB's enough to twist several links and make it unridable, so it does happen.
