The Extra Bar for Small Frames is for frame mounted Caress models that need a little extra lift. Bikes with smaller geometry or a top bar that drops down may need this extra bar for proper seat placement over the back tire. The extra bar lifts the seat approximately 4 inches and lengthens the seat placement by approximately 3 inches.
Please feel free to contact HamaxUSA customer service if you aren’t sure if this part is needed for your bike. We are happy to help with any fitting issues or questions.
