We chose to make our Crockett Carbon Handlebar in the two rises we like to ride, 20mm and 35mm. Our goal was to make a great performing carbon handlebar that provides a great ride feel while also having precision stiffness when you need it. Both rises come in a 35mm clamp diameter and have an 8-degree backsweep and 5-degree upsweep to put your hands, arms, and body in the perfect position to ride all day and forget about anything but having fun.   Every intricate detail was considered and designed by mountain bikers for mountain bikers. We are on a mission to make phenomenal products that support the sport of mountain biking. For every pair of The Crockett Carbon Bars sold, we will donate $1 to Crockett Hills Regional Park in California. We exist to support the trails we love and the people that take care of them. $5,000 donated so far!

Tested to spec: ISO4210-5 Giveback: $1/per pair sold donated to Crockett Hills Regional Park, CA My first mountain bike rides were straight up sufferfests in the Crockett Hills with my Uncle Dennis. I would end up walking most of the climbs and he would be waiting at the top for me, always fresh and ready for the next one. I think it's a fitting tribute that one of the first signature products from Trail One Components is named after the place where I learned to love mountain biking and those brutal climbs. These bars are a fitting first step when building out your new dream bike - or a solid upgrade for your current ride. - Brian Kennedy
