Titanium Frame There is a reason most frame makers do not like to describe their frames in detail. They often copy the dimension of existing bikes without understanding the benefits of design nuances. Altimo bikes approaches frame builds differently. This beautifully designed, incredibly versatile, ultimately functional, and skillfully assembled frame is purpose built and thoughtfully imagined. Made for cruising cities to back country roads to deep woods excursions and everything between, this frame is designed to be whatever you need it to be. The uniquely thick headtube body is made to accept headsets for either straight or tapered forks, and will never distort. Most titanium headtubes are half the wall thickness. All frame tubing is made with compound dimensions, to both enhance strength in key areas and add an aesthetic appeal not often seen in titanium frames. Disk brake brackets are hugged into the frame to look clean and add strength. The frame is also capable of using either hydraulic brakes are standard cable brakes. Eyelets are placed for dual water bottle locations, as well as for a rear rack. An extra set of eyelets are installed for electric bike torque brackets, or whatever your imagination favors. A generous number of frame gussets are placed in key areas to further increase strength and rigidity. The seatstays and chainstays are designed to allow for larger tires if desired. Bracket dimensions were made to accept the most widely available, the most durable, and the easiest to work on components. And yes, the derailleur hanger is replaceable.
