Product Details

Giant Reign SX 1 2019 Enduro Mountain Bike

With its slack head tube and seat tube angle and 180mm travel DVO custom-tuned Onyx SC front fork this Giant Reign SX 1 is quiet literally one of the best all rounders!

Key Features

  • ALUXX SL-grade aluminum frame with 160mm Maestro suspension
  • DVO custom-tuned Onyx SC, 180mm travel fork
  • DVO custom-tuned Jade coil
  • SRAM NX Eagle, 1x12
  • SRAM Code R hydraulic disc brakes
  • Maxxis Minion 27.5x2.5" tyres. Giant set it up tubeless - why this is good



27.5-inch wheels balance agility and control, giving you the ability to roll over rugged terrain, flick the bike at speed, change lines, and explode out of corners.


Updated Maestro rear suspension features a trunnion mount shock with a longer stroke and smoother feel. With 160mm of travel (and 180mm up front), it has the new Advanced Forged Composite upper rocker arm for increased stiffness and strength plus lower overall frame weight.


The lightweight and stiff Advanced-grade composite frameset features updated enduro-style geometry, so you can ride aggressive descents and rail corners with confidence.
