OM-DURO XL 27.5”+

To celebrate the life and times of SE’s founder, Scot Breithaupt, and SE’s motto of “BMX Innovations,” we created a bike like you’ve never seen before. The 27.5+ OM-Duro takes its design cues and aesthetics from the legendary OM Flyer and mixes in some radical mountain bike-style upgrades. This wildly unique bike comes in standard and XL sizes and features big 27.5 x 3.0” tires, a SRAM GX 1x10 drivetrain, Avid BB5 disc brakes front and rear, a new external bottom bracket, and internal cable routing for a dropper seatpost. BMX meets mountain bike; there are no boundaries.
