Short and stout sidewalls guard against pinch flats and denting from impacts: a pothole or a rocky descent. A generous 25mm internal rim width allows more tire contact with the road which supports you and your gear more safely and comfortably than conventional narrow rims. Tubeless ready with the use of Velotape. Item Specifications: Color, Black, Weight, 675, Hub Drilling, 36, Rim Depth, 21.
