good lock for commuting/supermarket bike?
Guys,
I've started to commute to work on my single speed bike this summer. So far I just roll the bike into my cubical at work and never have to worry about locking it outside. I plan to do grocery shopping and run errands with this bike too. So I'll need a reliable lock for it. My bike has 15mm lock nuts on both wheels. The seat post binder is bolt on, not quick release. So any shopping advice for a good lock and locking advice on the bike?
Thanks.
