A little while back i bought a lock an load from bikeberry.My first one. After a couple months the bell rotor broke right at the nut.I ordered a new one rode it for about a week an the same thing happened again in the same place,I can't understand why it's doing this.I thought maybe it might be the part itself. or am i doing something wrong as far as maybe pushing it down to far on the tire an createing too much preasure. If you understand what i'm talking about. Or is it just a cheap part i'm getting for bikeberry? Thank you for any help you can give.
