Bike Description

My 10 year old mountain bike just got stolen, it has a large size blue and white aluminium frame with some red. It has mechanical disc brakes, 3 front gears (the front derailleur hasn't been adjusted for ages and only the biggest front gear works) and 9 at the back if I remember correctly. Some rust, mostly on the fork. I have changed some of the parts over the years: the saddle is a new sharp looking decathlon saddle, I have changed the quick release skewers of the wheels (and saddle post) and a special key is now required to unlock the wheels/saddle. I had to change the crankset too. It is registered with Brasenose College under the registration number 1099, but I doubt the sticker will still be readable/there.
