My dropouts are really annoying me. Like The gap changes a few mm as it goes along. And so move the axles the have got stuck in the frame. Well one of them can move. So i gave up. Then thought i'll make a tensioner. Cut up plastic coke bottle + electrical tape. Few layers of plastic, then bum raped with tape. Then taped to the frame. Ridden it for about an hour now and seems to be fine.
