Had to run out to the garage to be sure my LeTour hadn’t “gone missing” ! I’m neither here nor there RE: elliptical chainrings. If the bike came with them, I leave them on. If I’m building from the parts bin, I’d use whatever brand elliptical chainring that had the number of teeth that I wanted and fit the crank spider. If a round chainring better met the needs, I’d use it. Not being a competitive rider, I’m not so sure I’m realizing the “benefit” of ellipticals but I certainly don’t notice any detriment.
