I know there are always a lot of chain cleaning/lube threads around but I had a search and couldn't find one about what to do on a long tour. I am thinking of 1-2 months plus where you would need to really service the chain while on tour rather than just temporary maintenance until you get home to do it properly.
My chain is currently is need of a good clean and I was going to use Finish line wet lube on it but thought I might start a tour suitable regime.
Obviously lube would be easy to carry but degreaser and cleaning kit wouldn't be so a full clean would be difficult. I was thinking of whether one of these clean lubes such as the wax ones would be good for touring. However, the only time I tried one, Pedro's Ice Wax, I didn't have much luck with it although I think that might have been my fault for not using it properly. I have heard good reports of prolink but in general it seems that some people rave about these types of lube and others have problems.
Another strategy could be a lube and wipe approach with a more normal lube and just avoid full cleaning.
Interested to hear from people who have been on long tours how they dealt with the issue?
