I already have a mountain bike which I currently use, but I want to get a tourer or racing bike.I can spend around £500 on it. I would like it to be lightweight, but not flimsy, It would need to be a bike that can easily fit a pannier rack on, as I plan on using it on long journeys. It would also have to have decent tyres because if they are not, I am the kind of person that gets a lot of punctures!Is the Raleigh Pioneer U1 Commuter Bike any good? Only seen a photo on the Halfords website, so I don't know.
