The Rockville Stem - Made in California

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.

The Rockville Stem strikes the perfect balance between performance and reliability. Our 3D stress analysis of the stem's geometry optimizes strength and weight. Aesthetics are aggressive yet sleek. One part, open face plate ensures ease of mounting and minimizes weight.

We are on a mission to make phenomenal products that support the sport of mountain biking. For every Rockville Stem sold, we donate $1 to Rockville Hills Regional Park. We exist to support the trails we love, the people that take care of them and to make your riding experience exceptional.
