The Rockville Stem is a unique Made in California stem that not only looks good but provides strength needed for all types of mountain bike riding. Striking a balance between looks and function, most stems can get the job done but do all of them look this good while doing it? The Rockville stem is only offered in 35mm diameter in either 32mm or 40mm lengths. Coming standard with rainbow finish bolts, the Trial One Rockville stem is easy on the eyes. 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.

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. – Brian Kennedy
