This is a carbon fiber cycling computer mount. It's designed to attach to handlebars that are integrated with the stem. - Includes adapters for Garmin and Bryton. "Like new" means that the cycling computer adapter was assembled once for confirmation. It has not been mounted on a bike. * The bolts and washers for attaching to the handlebar have been replaced with rust-resistant titanium ones. When assembling, be sure to apply grease to prevent seizing. Recommended for those considering a review of their cycling computer position. We look forward to your purchase.
