It seems logical that the eight pound Kryptonite Fahgettaboudit chain lock would "outperform" the lock that "Cycling Plus" rated as "best": the four pound Kryptonite New York 3000 U-lock. But, when I hunted down the CP test of the Fahgettaboudit chain, I was surprised by the results.

That massive chain lock lasted an impressive eight minutes against power tools. But the New York 3000 lasted ten minutes against power tools. So, unless someone MUST lock to telephone poles, or other objects too large for a U-lock, there is no good reason to haul around eight pounds of chain. The New York 3000 U-lock provides better security.

It is rare for crooks in most towns to use power tools against "average" bikes. (As opposed to a skilled Pro who has "targeting" a particular "high end" bike.) About 99% of the crooks use manual tools. The $24 OnGuard Bulldog Mini U-lock is just as strong against manual attacks as the Kryptonite 3000. So, for most folks, a compact two pound mini lock provides a high level of security. (When correctly attached to the rear wheel, just behind the seat tube).
