A tip I use on my bike(s) (once youv'e taken note of the reg number etc) is to write/print your name and address on a piece of paper and stick it down inside the seat tube, also into the handlebars. You can put as much info on the paper as you want.
Your bike ever gets nicked - Repainted - Reg Number scratched off but you spot a bike you think is yours, contact the police, tell them where you have seen the bike and what youv'e done to identifi it. They'll pop round with a spanner.
If the
new owner

objects to the police taking his bike apart then you can reasonably assume its a/your stolen bike.
The thing is
NOT to get your prize possession nicked in the first place

Youv'e spent a lot of money on your bike - Spend a little bit more on a couple of good locks.
