Size is a key element for success in BMX racing and the Annex Expert delivers. At the heart of the Expert model is a 6061 alloy 18.9\" top tube frame sized appropriately for riders who are not quite big enough for a Pro sized frame. 170mm 3 piece alloy cranks and 36/13 gearing get the power to the ground while the 28 spoke alloy wheels keep thing rolling fast and smooth. ###section### Product Specs FRAME MATERIAL: WHEEL SIZE: TOP TUBE LENGTH: CHAIN STAY LENGTH: 13.75\" HEADTUBE ANGLE: 73° SEAT TUBE ANGLE: 71° FORKS: Full Crmo 1\" Threadless BARS: Alloy 6.75\" rise STEM: Haro Mini Alloy front load 45mm ext HEADSET: Sealed integrated BRAKE MOUNTS: Welded BRAKES: Promax MV-87 Alloy V-brake - rear only FRONT HUB: 3/8\" axle: 28h Alloy Shell loose ball FRONT RIM: 28h Alloy double wall REAR HUB: 3/8\" axle: 28h Alloy Shell loose ball flip-flop REAR RIM: 28h Alloy double wall TYRES: Kenda SPROCKET: TBC CRANKS: 3pc Alloy race 155mm BB: TBC PEDALS: Mini DX Alloy SEAT: Velo Unibody GEARING: 36/13 WEIGHT: 16.9lbs ###section### Product Highlights Full Size Bike with a Shorter Top Tube and geometry to Suit riders who are 4ft - 5ft 4\" / 120cm -160cm BMX Racing specific bike 6061 series alloy frame 100% chromoly fork Promax V-Brake and lever ###shogun-image-section###
