PROTAPER J-Unit 680 Black/Stealth Rise 1 Handlebar

The ProTaper J-Unit 680 Rise 1 Black/Stealth handlebar was developed using NASA anthropometric data to establish the average hand size of children aged 6 to 10. This data was used to determine the ideal grip diameter of approximately 22 mm, and then the appropriate handlebar diameter of 15.6 mm. The ProTaper J-Unit 680 Rise 1 Black/Stealth handlebar is therefore designed specifically for children up to around 10 years old. This ProTaper handlebar must only be used with ProTaper J-Unit grips, sold separately.
