Fly's Sion was built as the perfect ramp-blasting machine, equally capable of handling business when it comes to heavy street riding. With help and input from Larry Edgar, Josh Dove and Sergio Layos the Sion has been built for speed and riding control, with an absolute ton of aftermarket Fly parts, like Fuego Tyres, Volcano Stem, Sierra Seat and more Ruben parts. A full chromoly frame, forks and bars ensure reliable durability from the Sion with front and rear sealed hubs, a 3-piece crankset and chain tensioners helping the rest of this setup feel solid. ###section### Product Specs FRAME MATERIAL: 100% Chromoly WHEEL SIZE: 20" TOP TUBE LENGTH: 21" CHAIN STAY LENGTH: 13.4" HEADTUBE ANGLE: 75° SEAT TUBE ANGLE: 71° FORKS: 100% Chromoly with 1-Piece Steerer Tube BARS: 100% Chromoly STEM: Fly Volcano Front Load, 6mm Rise, 50mm Reach HEADSET: Trebol, Sealed Bearing, 6061-T6 Aluminium BRAKE MOUNTS: Removable brake mounts BRAKES: Trebol Springhammer FRONT HUB: Trebol Bueno, Sealed Bearingm 10mm Female Axle FRONT RIM: Fly Piramide, Double Wall REAR HUB: Trebol, Sealed Bearing, 14mm Male Axle, 9T REAR RIM: Fly Piramide, Double Wall TYRES: Fly Fuego 2.30" (Front and Rear) SPROCKET: Fly Tractor, 7075 Aluminium, 28T CRANKS: Trebol 3-Piece, 175mm Arm Length BB: Mid Sealed Bearing PEDALS: Fly Ruben Graphite, Nylon/Fibreglass compound SEAT: Fly Aire Tripod GEARING: 28/9 WEIGHT: 24.91lbs ###section### Product Highlights Great for riders who are between 5ft and 6ft tall (150cm - 180cm) Best suited to skatepark use but can be used on for all types of Riding High-quality Chromoly construction Sealed bearings throughout Chain tensioners to help keep your wheel in place ###shogun-image-section###
