patrick.leath

Great product. It makes long rides a lot better.

lablover1028

If you ride far, you need to buy this product. I will never be able to desribe how much this helped my hand and overall comfort.

Madsquirrel

I love the throttle boss, and it's easy to adjust for perfect positioning.

apowell

This is my second throttle boss. Even though I have cruise on the new bike, this is a must. I don't get cramps in my hand any longer. This is better than the plastic ones you can buy.

bzinezi

Great product.
