Schwalbe Procore Pack 29 inches
Not going back
Put this on the rear wheel of my Niner ROS 9 (hardtail) and it´s a game changer. So good to not have to worry about banging up the rear end when running lower tyre pressures. Didn´t feel like it added any significant weight. I think these will become like dropper seat posts have for most folk - get used to the convenience/ride improvement and folk won´t want to ride with out them.
