| description | The utility model discloses a sandwich type bicycle rim which comprises a tire position hole groove and a closed cavity, wherein the tire position hole groove and the closed cavity are arranged in an up-and-down mode, an inner tube is contained inside the tire position hole groove, and braking surfaces are formed outside the side faces of the tire position hole groove. The sandwich type bicycle rim is characterized in that the tire position hole groove at least comprises a metal alloy layer, the outer surface of the tire position hole groove and each braking surface are respectively provided with a carbon fiber layer, and the metal alloy layer is wrapped by the carbon fiber layers, so that a sandwich body is formed. A CFRP-alloy material-CFRP sandwich structure is formed on a braking side, so that good braking heat dissipation and steady supporting effects are achieved; the characteristic that metal materials are resistant to high temperature is utilized, frame burning risks of the rim are effectively reduced |
