The numbers show the Ibis Ripmo mountain bike to be longer than it’s smaller wheeled brother, the HD4. Riding the bike shows differently. In my opinion, because of its steeper head angle and MUCH steeper seat tube angle, the Ripmo rides the mountain bike trails far smaller than it might appear on paper.
Additionally, my HD4 is set up for ultimate downhill ability, complete with a 170mm fork. Compared to my HD4 set up, the Ripmo mountain bike is almost two degrees steeper in head angle and the wheelbases are virtually identical. The BB drop and the ratio of chainstay length to wheel diameter on the Ripmo also contribute to this feel.
Both the Ibis Ripmo and HD4 are great bikes. I hope this video helps you to find the best fit!
