Ok first of all u need 1 (3/8) bolt and 2 (5/16) bolts. second, dont tighten it because it creaks, you will break the foldy mech right in half. just tighten the bolts not too much, and push the bars towards the brake. over time it shouldnt creak as much, mine creaked in the beginning and stopped after liek 2 months. and make sure u did it right, if u didnt remove the little bar in the front of it, thats a problem.
