The Revo 20″ allows you to get your first taste of the BMX world on a solid and well-designed bike. Radio took extra care when hand selecting the components on these bikes to ensure that the bike could be ridden straight out of the box, simple to work on and maintain, but also easily upgradable over time. Despite the low price-point, the Revo is packed full of great features like 25-9 gearing, tapered fork legs, and short/responsive pro-inspired geometry.SpecificationsFrame - Radio 'Revo 20' frame, full 1020 hi-tenFork - Radio 'AM 20' fork, 1020 hi-ten, Cr-Mo steererHandlebar - Radio 'Revo 20' bar, hi-tenGrips - Radio 'AM' grips, flangeless, 150mmStem - Salt 'AM' topload stem, 50mm reachHeadset - FSA a-head-set loose ballBrake lever - Radio 'AM' alloy brake leverBrake - Radio 'AM' alloy u-brake rearCrank - Radio 'Rookie' OPC forged crank Cr-Mo, 170mmBB - USA size, loose ballPedals - Radio 'Rookie' nylon pedalsChain - KMC 'S1' chainSprocket - Radio 'Rookie' sprocket, steel, 25TDriver - 9T, cassetteFront hub - Radio 'Rookie' hub, steel, Lb, 3/8″s, 36HRear hub - Radio 'Rookie' cassette hub, steel, Lb, 9T, 14mm axle, 36HFront rim - Salt 'AM' rim, straight single wall, 36HRear rim - Salt 'AM' rim, straight single wall, 36HSeat - Radio 'Century' slim combo seatSeat clamp - Radio slim alloy seat clampTyres - Radio 'Rookie' tyres, 20″x2.2″, front & rearWeight 12.22kgFrame geometryTop tube length - 20″Chain stay length - 13″Head tube angle - 75°Seat tube angle - 71.5°Bottom bracket height - 11.75″Standover height - 7.8″Handlebar geometryRise - 8.75″Width - 29″Backsweep - 11°Upsweep - 2°
