technical Description
Frame/fork Frame with a 20.5" top tube and 13.75" stay and a 4130 chromoly steel down tube and fork pivot. The very short back end makes it easier to perform stunts on the rear wheel and the frame geometry also ensures excellent balance when the bike is off the ground. We have used 4130 chromoly steel, which is the BMX standard. This alloy which has the best weight-to-strength ratio in street BMX riding.
Drivetrain/pedals 4130 chromoly 3-piece chainset. Mid bottom bracket with sealed cartridge bearings. 175mm crank. 39-tooth chainring. Reinforced Kmc chain. We have chosen this 4130 chromoly 3-piece chainset because of its exceptional quality. It is fitted with cartridge bearings (which do not require any maintenance) in a Mid bottom bracket, whose size provides an excellent weight-to-strength ratio. The rest of the drivetrain enables the rider to accelerate rapidly before jumping.
Handlebars/stem/rotor Oryg 360° rotor. 645mm reinforced Hi Ten steel handlebars (3° back, 8° up). Aluminium Aheadset stem. The rotor allows for 360° handlebar rotation, enabling the rider to perform all types of tricks easily. The handlebars have also been designed for easy stunts. The aluminium Aheadset stem is used to ensure maximum strength. The large, textured grips provide optimum comfort and are fully shock-resistant thanks to their end caps.
Wheels/tyres Machined aluminium 48-spoke rear rim with 14mm axle. 36-spoke front rim. K-Rad 20 x 2.1 front tyre and K-1040 20 x 2.1 rear tyre. The aluminium rear rim has 48 spokes and a 14mm axle. The aluminium front rim has 36 spokes with a 10mm axle. To ensure optimum versatility on all types of surfaces, there is a gravel front tyre and an all-round rear tyre.
Brakes Adjustable aluminium 2-finger levers. Aluminium Tektro V-brake calipers. BMX street bikes usually have U-brakes, but we have chosen V-brakes for the power and performance they provide.
Saddle/seatpost Dirt saddle with reinforced sides.
Accessories 2 pegs included.
