Discover the ProTaper J-Unit 680 handlebar, designed for comfort and control in mountain biking. Performance and ergonomics combined!
The hanger ProTaper J-Unit 680 Rise 1/2 Black/Stealth was first developed by acquiring anthropometric data from NASA, determining the average hand size of a child aged 6 to 10. These data were used to determine an ideal handle diameter of around 22 mm, and then to determine the appropriate hanger diameter (15.6 mm). The hanger ProTaper J-Unit 680 Rise 1/2 Black/Stealth is therefore designed specifically for children up to around 10 years of age. This hanger ProTaper is to be used only with ProTaper J-Unit handles, sold separately.
