The flange is not very big but enough for 3 friends who are hiking. Fast delivery, product solid and well finished look. Only downside; Engraving: 1_ The codes marked with the product to clarify the position and front or rear are not the same on Amazon pub and mail that is sent and ESPECIALLY 2_ I asked behind and I had to !! Problem should not have the same idea of front / rear and only explained anywhere. But overall I'm very happy; product with a very good price / quality ratio
