Built around a classic frame design, including SE's looptail, the OM Flyer includes some modern touches to help you keep up with the competition. The 4130 Cr-Mo steel frame gives you the feeling you're on a 1st gen OM Flyer, the American bottom Bracket, and 3 piece 39T cranks continue to provide that retro look. Things change with the Alex DM24 rims laced to sealed cartridge high flange hubs rocking hollow axles, making this bike feel stiffer and fly like it never has before. Rock the old school look, while keeping the new school technology.
