Intelligent Design
In order to make a stem stronger, you need to start with a larger stronger tube. In order to provide extra strength and still use stock bushing, JD Performance starts with a larger diameter tube and reduces it where the bushing is positioned. This will allow for stronger bend resistance and allowing for all the stock bushing and clamps to fit perfectly. No other company has this much attention to detail.
Adjusted Fit
Are you to tall for your quad? Adding +1 or +2 inches to your stem could provide extra comfort for those who feel a bit cramped. Moving the clamps +1/2 forward can even adjust the balance of the quad by changing the position of your body.
Exact Engineering
Many companies are building stems, but very few understand what stresses your bike endures while riding or racing. JD Performance uses their years of experience to make sure that every stem has solid construction that will provide years of flawless use
