Bike Update - Scott Aspect

Hi Guys! I've been riding the Scott lately on some XC routes round where I live. I've also upgraded the brakes and changed the rear wheel due to the freehub on the old one giving up on me. The brakes I went for were Shimano BR - M596. I went for these because of the low price they were selling at from RoseBikes and also because even though the BR - M485's I had on previously were causing problems, they only started this towards the end of their life and they had lasted over 3 years which I think...
