The Rockville Stem strikes the perfect balance between performance, reliability, and good looks. We wanted a stem with a sleek, aggressive look with as much material removed while still passing all of our ISO testing and 3D stress analysis. It comes in two different lengths, a 32mm and 40mm length option, both with a 35mm clamp diameter.
We are on a mission to make phenomenal products that support the sport of mountain biking. For every Rockville Stem sold, we will donate $1 to Rockville Hills Regional Park in California. We exist to support the trails we love, the people that take care of them, and to make your riding experience exceptional.

My first mountain bike ride was oh so many years ago at Rockville Hills Regional Park in Fairfield, California.
I've loved the unforgiving terrain, impossible climbs and scary tech of Rockville from the very start, and it's still a wild place to ride.
I was lucky to have such harsh terrain as my home base, as it prepared me for all the diabolical singletrack I've taken on since.
