Managed to snap the chain on my new bike within 5 minutes of riding it up and down the road. Luckily is wasn't because I'm a fat b'std but because it was faulty. Got a nice new upgraded chain from the bike shop. I have to say I'm really impressed with the service there and Gary, the owner is very friendly.
I've now moved all the bits from my old bike (lights etc) and am ready for the ride in the morning. I also bought a new cycling jacket in nice quiet flourescent yellow so can even go out if it's raining.
