reviving this thread, but I'm looking at the Kryptonite systems.
portable security or in-place security? for in-place security you'd want a 16mm or thicker chain which kryptonite doesn't make, ideally run through the frame of the bike and into a ground anchor. these thick chains are really heavy so aren't really portable unless you don't mind lugging around 20+ pounds of steel.
chains here:
Chain Locks: Lockitt.com
for portable security, ideally you'd want to lock the bike to something. it looks like we might be able to get the shackle of a large u-lock through parts of the 09's frame, if that's the case the 09 could be locked to a bike rack or other slim metal post using a u-lock. in which case, the kryptonite new york lock mc or better yet the kryptonite m18 (18mm shackle version of the ny lock, but it's not sold in the states) are among the toughest u-locks you can get.
in addition to the u-lock, get an alarmed xena disc lock, ideally clipped onto the rear rotor. they've got different models with different locking pin diameters with the smallest one being 6mm - check to see if the holes in the rear rotor are at least that big.
i'd verify all of this for myself but my bike hasn't come in yet.
