Or B'Twin U-Fit 80 fork, with 80 mm of travel and an innovative fork stiffness adjustment based on the rider's weight (55 to 105 kg).

    • A little frustrated

      Used for
      Tomorrow will be the 3rd visit to Decathalon for my 340 which I purchased about a month ago. Started having issues with chain today. It slips and won't change gears. Also the gear shift on the left side handle bar has become loose. I'm thinking of exchanging for the 540. I didn't want to have to spend more money. I just don't want to be "that customer."

      We were looking for a bike for our ever growing teenage son who has just started a paper round and needed to be more independent. A perfect bike!
      Price was reasonable. Also loved the colour!

      Dear Sir,
      I'm sorry to read that the pedal had not been tightened correctly.
      I'm glad that your local store was able to exchange your bike for you. Could you reply with the name of the store please?
