is so was first explained to me I was almost embarrased to have been
using a cable lock for years. Anyway, from my experience with owning a
roadbike equipped with disc brakes, I advise you sell the bike.
Why are cables so easy to defeat? I use them for both motorcycles and
bicycles so I"m very interested to hear if I'm being silly.

Dear Paul,
The wire of a flexible cable can't be hardened as much as a solid,
unbending chunk of metal, so bolt cutters go right through it:
"Simple cable locks, however, are only sufficient for use in low-risk
areas. Even the largest diameter unprotected cable can be quickly cut
with bolt cutters."

A chain is flexible, but the links are not, so they can be hardened.
Any lock is better than none.
Here's a rough-and-ready test by a curious bicyclist:

His hacksaw and bolt cutters made short work of the cable locks, but
the cable locks would obviously would stop the casual thief just
looking for something that isn't red hot or nailed down.
Cheers,
Carl Fogel
