Looking for advice on a good mtb frame to take on some travels across Europe and S Asia. I plan to mix cycling legs with travel by trains, buses and the occaisional flights, so I'm looking at options for an easily transportable mtb, which I can stash in hostels or hotels and take on trains etc without too many hassles. Ideally something which will also serve for XC and commuting once home.
It would needs to be able to take a pannier rack, should be light and possibly foldable. Some options I came across are:
Slingshot Fold-Tech
Montague SwissBike
Ibis Tranny
Dahon Flo
Forgetting about foldability and using a bike bag
Getting couplers fitted to a steel frame
The last would be too time consuming. No one seems to stock the flo and it's pretty costly. The tranny looks amazing but expensive and not sure whether it could take a rack. Does anyone have experience of the foldtech or swissbike? Swissbike has several models, it looks like they're all the same frame with different components?
Any thoughts or tips much appreciated.
