Our engineering team began by researching anthropometric data from a NASA database. We determined the average hand size of a 6-10 year old which set the team into motion. Normally, grip diameter is a result of adding material to a standard handlebar size. For the JUNIT ProTaper handlebar system, we flipped the script. We began by determining the ideal grip diameter, and worked inward. The result is a handlebar and grip that’s ideal for a smaller ergonomic profile. JUNIT ProTaper handlebar and grip are designed to be used together. For an element of added safety, the grip utilizes a built in bar plug that will never fall out. The JUNIT ProTaper handlebar system works with all existing shifters and brakes, as the JUNIT ProTaper grip features standard component mounting diameter.
