Glad you like it so far. If you go with the Marathon, avoid the plus models UNLESS you need a very flat-resistant tire. They feel much heavier and slower than the Big Apples. The Marathon Racers are nice tires but spendy.

At the risk of hijacking the thread (not my intent) what DT will you buy? I am totally sold on internal hubs at this point after years of being a derailleur convert I realize they have gotten very good while many people have not been paying attention.

My Swift is still my favorite folder by far and doesn't look like anything will unseat it soon either. You could also try Tioga Comp Pools (very light and fast) as a choice but not very flat resistant for most people. So far I've had not issues. Of course now I'll get a flat.

Enjoy the bike and let us know when you get it sorted out.
