    • Just buy it
Color: Black
Way less than a bike shop, easy to install, and gives you the option of a much higher rise. Simply a great value that’s hard to beat if you’re willing to install yourself. And I am far from a mechanic.

    • Excellent Choice for Updating a Bike
Color: Black
Excellent choice for updating a bike. Be prepared to have to cut the length to make it look right. I was hoping that they made one shorter than the shortest one listed. I still had to cut about 1" off the top.
