Fixed more difficult for thieves?

But a bike with really high saddle, really low drop bars, fiddly road strap pedals or even worse, clipless aswell as tight racey geometry and drop brake levers would probably all freak a thief out just as much if not more.

And coming from what I've seen, theives and hoodlums always ride these low saddle heavy mountain bikes pacing at 3mph looking COOOOL & talking on their mobile phone going "innit bruvs/blood".

Not that I don't say innit or anything... :P

So going from that to a road bike is certainly going to feel uncomfortable and uneasy.

But, that isn't always the case. Unfortunately SOME thieves know about bikes...
