  • The bike is available in sizes small through to extra large. A wide range of riders fit the bike.

  • There are tabs for a chain guide on the bike.

  • The bike uses X-Fusion’s Manic dropper post, which is reliable and easy to operate.
  • Testers agree the SWAT compartment in the downtube of the bike is an excellent place to store snacks and tools.
  • The bike comes with a lifetime warranty on the frame.
  • A molded protector on the bike's chainstay dampens the noise from chain-slap.

6 reasons not to buy

  • Some testers found they experienced frequent pedal strikes because of the low bottom bracket on the Stumpjumper FSR ST.
  • With greater anti-squat than other mountain bikes in its category, the Stumpjumper FSR ST is prone to pedal bob if the climbing lever is not engaged.
  • Experts note that taller riders may find the reach is shorter than the reach on other bikes in its category.
  • One expert found the bike unstable at high speeds due to its compact size and steep seat tube angle.
  • Test riders agree that the bike's geometry and riding position allowed them to feel trail chatter more than on competitors' bikes. This can lead to fatigue.
  • The Stumpjumper FSR ST is not built to handle big hits or aggressive terrain.

Bottom line

The Stumpjumper FSR ST is a bike with 120mm travel in the rear and 130mm in the fork. It offers riders excellent small bump compliance. It’s not meant for big hits or aggressive trails. It does best on smooth, rolling terrain. Testers found it easy to bottom out. The bike is a capable climber but only when the climbing mode is engaged. They also found that their body fatigued quicker over rough terrain than on other bikes. Pedal strikes are also an issue with its low bottom bracket. The bike has a handy SWAT storage compartment for tools and treats. This bike has a lifetime warranty but if you are looking to tackle technical gnar it's probably not for you.
