Focus Whistler 3.9 29" Hardtail Mountain Bike 2020

The ideal introduction to off-road riding, the Focus Whistler 3.9 29" Hardtail Mountain Bike comes equipped with hydraulic disc brakes, a reliable 100mm RockShox suspension fork and durable Shimano SLX components. The 1X drivetrain keeps maintenance low and doesn't come at the cost of gears thanks to the wide-ranging 10-51t 12-speed cassette.

Smart Sam tan sidewall tyres deliver a sporty look and the 29" wheels will roll smoothly over rough trails. The lightweight 6061 aluminium frame won't feel cumbersome on the hills giving you the confidence to ride new trails or push yourself harder on a favourite local loop.


  • Shimano SLX components are perfect for a sporty hardtail mountain bike
  • Tan sidewalls tyres look great
  • Shimano hydraulic disc brakes ensure that your stopping power won't be compromised come rain or shine
  • Grippy Schwalbe Smart Sam tyres
