The K-Edge Adjustable Boost Stem Mount for Garmin 1-1/8" Steerer Tube Diameter is built for riders who run compact handlebars and want a computer mount that stays rock solid. Its 1cm base rise helps larger cycling computers sit neatly above the stem without rubbing, making it ideal for steep upward stem angles and shorter stems. Designed for reliable performance in rough terrain, it keeps your Garmin unit secure where you need it, with a lifetime guarantee against material or manufacturing defects.
