Poor design so did not fit properly, poorly made so started to fall apart instantly. Returned.
Thank you for taking the time to post a review of this bag. I'm sorry to read that the quality was not as we would expect. Generally, feedback is positive for this bag therefore I will forward it on to the design team to investigate further. As we don't have details of the quality issues, I will ask them to check the whole item. The angle of the top tube can in rare cases make it awkward to fit as the straps may not be long enough but generally speaking it's pretty universal.
If you are not entirely happy with the design, please feel free to return it to us for a refund or an exchange with your receipt or Decatlon card.
