Rant's Bangin' 8 Cranks were built for those shredders on a budget. We were all a beginner at one point and we all needed affordable and reliable parts so that is where Rant have aimed with the Bangin' 8 Cranks. The crank arms are made from 4130 trapezoid shaped, heat-treated tubular chromoly that prevents flex while still offering a grindable surface. The 3-piece design is finished with a heat-treated, 48-spline chromoly spindle. Compatible with both RHD and LHD sprocket bosses these are a solid option for beginners or as that first upgrade. ###section### Product Specs Crank Type: 3-Piece Drive Type: Bolt Drive Spindle Diameter: 19mm Drive Side: Left & Right Compatible Includes BB Bearings: No Weight: 1000g (35.2oz) ###shogun-image-section### Colour: Chrome, Gloss Black; Size: 170mm, 175mm, 165mm
