Hello! So for christmas I got money for buying a chain, I already use the OnGuard Pitbull mini DT u-lock and haven't had any problems; it's just that it can get really hard to find a suitable locking spot, bike racks are not common in this country yet; many times I end up locking the bike to a metal fence that really does seem weaker than the lock itself because there's nowhere else to go . So, i'm getting a Pragmasis chain (http://securityforbikes.com/security-chains.php) long enough to go around an electricity pole. My main question is, is it worth it to go with the 13mm one? or is the 11mm good enough for bicycles? i don't think bike thiefs in my city are using angle grinders of 4ft bolt cutters yet but i don't want to spend the money on the 11mm one if it's really not good enough. Has anyone had a bad experience with an 11mm one?
Merry christmas to all
