HRP plates are set up to work across multiple handle bar sizes

(The rider age listings are approximations)

 

Pro plate = 7.5” rise bars and up  (15& over riders)

 

Expert Plate = This is the HRP “one size fits most” works best in the 5” to 8” bar range,

    but can be used on basically anything with a crossbar.  I have even seen these used on striders and mini

    without a problem, but they look big on the small bike.  (9-16 year olds)

 

Mini/Cruiser = 3” to 6.5” rise bars  (12 & under and all cruisers)

 

Micro mini = anything without a crossbar up to 4” rise bars.  (8 & under)
