What Our Gearhead(R) Experts Are Saying:"I picked this up when I wanted to move my Macro XL onto an aluminum handlebar mount instead of running the rubber strap, and it solved the problem instantly. At 6 grams you genuinely forget it is there, and the Composite Matrix construction feels solid enough that I have no concerns about it holding up long term."Sometimes the right fix is a small one. The Lezyne LED Handlebar Mount Adapter is a 6 gram Composite Matrix piece that replaces the rubber strap on 2016 and later Macro XL, Power XL, Super XXL, and Deca XXL lights, opening up compatibility with Lezyne's Aluminum Handlebar Mount, Composite Handlebar Mount, and Aluminum Helmet Mount. If you have already invested in a quality Lezyne mount and want your light to work with it cleanly, this is the part that makes it happen without any workarounds.
