I have Ultegra drivetrain, with 11-25 cassette. I may be taking some time off to go to Europe in the summer and would like to take the bike with me. However, there will be much more climbing than in Tokyo, and I'm thinking about getting a spare 28 or 30 mountains cassette.
But I have doubts if the same chain can function with both 25s and 30s? Or do you have to get another (longer) chain too?
