Well after retrieving the bike from its unscheduled flight across the room (it must be fairly aerodynamic as no breakages just some unguleing) and searching, took me nearly half an hour to find the back of the rear caliper, and almost as long to get it back on, since it's all installed on the rear wheel. I've decided to cut the top length of the chain off as it was so warped I couldn't get the chain guard on, and with the guard in place no one will see the chain anyway. I'm having a bit of a chill out now, before I battle with this kit again. I am determined to win though, I will take no injured in this battle its win or die.
