Ever wonder what a man like Jan Heine would want in a custom titanium bike? Well, this is merely speculation, but Firefly just posted a photoset of a ti bike with those 26″ Rat Trap Pass Compass tires and a titanium Tubus rack, labeled Jan Heine. So, speculate all you want, but I’m guessing this one will be in a forthcoming issue of Bicycle Quarterly. See more of this insane bike at the Firefly Flickr.
