After speaking with H&S, I took the recommendation of their 4 inch riser bars for my bean sprout kid. It was a straight forward bolt on install. No need for adapters or extensions.
From purchasing to install a faultless service provided. Fast shipping is wonderful.
The ASV levers for the pw50 are a must for smaller riders! Amazing improvement to small rider’s confidence. Thanks again for a great consumers experience.
