I am selling a new Wahoo Element Roam for a friend. She used it only twice, but found that a Garmin was a better fit for her needs during a 30-day off-road bicycle race this summer. The Wahoo comes with all the items, including the safety tether, which is usually a separate purchase. She is asking for $300 for the entire setup. If you are interested, let me know. I have the unit and box at my house.
