Im after a little bit of advice if any one can help then it would be much appreciated. I have decided to take my track bike apart over the winter and give it a tidy up. Mainly so i can learn a little bit more about how the bike goes together and what parts need to be maintained. I have decided to take the rear swing arm off and have found that there is a strange shape bolt/insert inside the rear swing arm it looks like i need a special tool to remove it. Has anyone come across it before and do they have the tool to remove it. Any other advice any one can offer would be welcomed. I also need to get the chain off but dont want to fork out for a new one as this one seems ok. Is there a way to remove it without having to replace it?
