lots of interesting theories, good reads, thanks.
anyway, fact is that a waxed chain runs much smoother than a oiled chain, the waxed chain also covers lots more distance than a oiled chain. also its much cleaner than a oiled chain, and stays clean, its does not collect dust and dirt. same as for rain rides, last weekend i had to ride 102k most of it in heavy rain, I had to get to my hotel reservation since the next day I had to get home. normally I would stop and not ride in such conditions a long time. the chain is still behaves great, no new wax, close to 1000k now. perfect!
