Not much of an update, other than to say avoid pot holes! I've managed to hit 3 in the last few months, and all with some force. I've had a few components changed, but still had a slight wheel wobble when turning from left to right at speed.
So yesterday (Friday) I had it checked out at work, and it turns out my front wheels aren't round any more lol.
So a fair few wheels weights later, and all is pretty much 99% perfect.
This may explain why my front tyre has been loosing psi, so either I'm going to have to find some nice second hand wheels, or look at my options.
