im not giving up on my bike, i just wanna start on another one. and the chain broke cus since it was so loose, the chain wuld fall off and the bike wuld still go... so the chain sometimes got stuckk forcing it, i guess? and i actually did learn alot from building this bike... but because my bike didnt have horizontal dropouts, i never bothered learning what it meant. honestly tho, idgaf what u sayy(:
