How to make a road bike lighter?

I was given a Specialized allez sport 2013 for Christmas, and I absolutely love it! I've taken it for a few rides and immediately realise how much less inertia there is with lighter bikes! I would love to get into racing, and I'm about to join a road biking club so I can start doing some longer roads races!... show more I was given a Specialized allez sport 2013 for Christmas, and I absolutely love it! I've taken it for a few rides and immediately realise how much less inertia there is with lighter bikes! I would love to get into racing, and I'm about to join a road biking club so I can start doing some longer roads races! My bike weighs 10kg (including bottle cage, two light attachments [no lights], tiny bell, and a saddle bag weighing roughly 500g). I'd like to make my bike a bit lighter after finding out how much weight affects modern road racing, without cutting or drilling anything! I need cheaper things (not new forks handelbars etc. and not removing my bum bag!)

Any ideas much appreciated!
