The Jet Block 20\" is the most affordable full size 20\" BMX we currently offer and a great entry level bike from Jet. Features include Hi Ten 20.25\" top tube frame, 8\" High steel bars, 3pc Forged cranks with sealed mid BB, 9t Sealed cassette hub, Padded seat & post combo & much more. It is unheard of to get 3-piece cranks and sealed hubs and bearings at this price point - all of these things mean the bike is lighter, stronger and harder wearing than parts normally found at this price. ###section### Product Specs FRAME MATERIAL: Hi Ten Steel WHEEL SIZE: 20\" TOP TUBE LENGTH: 20.25\" CHAIN STAY LENGTH: TBC HEADTUBE ANGLE: SEAT TUBE ANGLE: FORKS: Hi-Ten Steel BARS: 8\" Hi Ten Steel STEM: Alloy Top Load HEADSET: 1 1/8 Aheadset BRAKE MOUNTS: Welded U-Brake BRAKES: U-Brake FRONT HUB: Looseball FRONT RIM: Single Wall Alloy REAR HUB: 14mm Sealed 9t Cassette Hub REAR RIM: Single Wall Alloy TYRES: Innov Street 2.25\" SPROCKET: 25t Steel CRANKS: 3pc Chromoly 170mm BB: Sealed Mid PEDALS: Platform Plastic SEAT: Padded Combo GEARING: 25/9 WEIGHT: 25.4lbs ###section### Product Highlights Full Size Bike with a Shorter Top Tube and geometry to Suit riders who are 4ft - 5ft 4\" / 120cm -160cm A great all rounder suitable for any type of riding Sealed Rear Cassette Hub Our Most popular 1st Bike Strong 3 Piece Cranks With Sealed Bottom Bracket ###shogun-image-section###
