The Academy Trooper BMX is a dialled BMX bike with some new upgrades on the 2021 model. It now comes with a sealed mid bottom bracket and sealed hubs for a high quality ride. This bike is for somewhat smaller riders with a 19.5" top tube and 20x2.3" tyres. You still get the tough Hi-Ten steel frame, forks and 8.5" rise bars. The 3 Piece forged crankset is paired with a 25t sprocket for a reliable ride. As with most Academy bikes it is built to give you great value so that you can get the most out of every ride.

Features

  • Frame: Academy Trooper 20″ with 19.5” TT Hi-Ten
  • Forks: Academy BMX Trooper 20″ Hi-Ten tapered legs
  • Crankset: Academy 3pce Forged 8 Spline, 170mm
