Mafia OW Bomma XL 29" Bike
The XL version of the @oneway_corey signature OW Bomma, built for taller riders. You get the same pro-level, ready-to-ride spec as the standard OW Bomma on a bigger frame: a 620mm top tube (up from 606mm), 458mm reach and 784mm standover give you more room without losing the wheelie and bikelife feel. Mafia's own rider guidance puts riders around 6ft 3in comfortably on the XL.
Spec highlights include a Shimano Cues 10-speed drivetrain, Shimano MT200 hydraulic rear disc brake, high-engagement sealed rear hub, a 6061 T6 hydroformed alloy frame with integrated peg-mount dropouts, a bespoke 32t CNC chainring, SunRingle Duroc35 29" rims and Lagos Snakeskin "S" super-soft compound tyres. It's built to buy and ride, with no upgrades needed.
