Hi, I'm looking to buy a second bike to commute to work, currently using my 'heavy' mountain bike. I have a budget of max £700 and am looking for a sport hybrid type bike. I have narrowed it down to TREK 7.5 FX, TREK 7500, Ridgeback Flight 02, ridgeback Rapide supernova, Specialized tricross or Specialized sirrus elite. My commuting journey is mixed. Road30%, pavement40%, 10% gravel, 20% mud footpath, many speed bumps, mount many pavements, only one short steep up hill section. I hope someone with the knowledge of the above bikes can give me some advice. Thanks, Sion.
