Bike locks and alarms
I used the search here, but without being able to search thread titles the results are less than wonderful. For immediate use I got a Bell cable lock, but I know they're less than wonderful.
I don't want to have a HEAVY clanking U lock on the bike 100% of the time so what are some options that make the bike reasonably secure to all but the most determined thief? Sure there are "reviews" on the web, but I'm suspicious of the results that can easily be skewed by ad revenue.
Also, are locks with vibration alarms of any real use?
Oh, my bike for now is a Cannondale Mtn bike without disk brakes.
