Decathlon Rockrider ST100 Mountain Bike, 27.5", Red, UNISEX FRAME, Medium
 

With a very marked slope on the top tube and a wide range of sizes (from S to XL) The ST100 mountain bike frame is UNISEX.
 

A LIGHTWEIGHT, COMFORTABLE, FUN FRAME

  • It isn't always easy to get the right position on a mountain bike. Our designers created a frame that's easy to get onto.
  • The 100% aluminum CGF frame (Comfort Geometry Frame) is both comfortable and easy to handle. The slope angle has been designed to keep your back straight, while the rear bases were shortened to make the bike very agile in turns.

FRONT SUSPENSION

  • The 80 mm front suspension helps you get started with overcoming obstacles on slightly uneven trails easily.
  • Its mechanical spring is a stamp of reliability. And the fork is particularly easy to maintain. 
  • To adjust the stiffness? It's very easy using a single dial.

DERAILLEUR & DRIVETRAIN

  • 3 x 7 speed chainrings, 21 speeds total.
  • 2 easy-to-use grip shifters on the handlebar.
  • Left (chainrings): control ascents/descents.
  • Right (speeds): more precise control over your pedaling.

HANDLEBARS, STEM, GRIPS

  • With a stem that tilts 10 upwards, the riding position of the ST100 is raised, accessible, and comfortable. 

SADDLE

  • The saddle of the ST 100 is welded to prevent any movement of the saddle. Your comfort is our priority after your safety, we've added an exclusive wider Ergo fit saddle with a hammock shape.
  • Easily adjust the height of your saddle with the Flex steel seat post (350mm or 400mm long depending on the bike size). Its smaller 27.2mm diameter provides your seat with natural flexibility, 30% more than a standard solution.

V-BRAKES WITH PADS

  • Two V-Brake pads for effective braking.
  • These brakes are composed of calipers that exert more or less pressure on the rim to slow or stop the rotation of the wheels.
  • Thanks to the special design of the ST 100's aluminum brake levers, you only need two fingers to brake.

27.5" WHEELS & TIRES FOR DRY TERRAIN

  • The wheels of the ST 100 are tolerant and robust, with 27.5" double-walled 28-spoke rims (26" for the XS size). Start overcoming obstacles fearlessly, including small rocks, cracks, holes and bumps!
