Okay, so when you go for a ride and stop somewhere for a bite to eat or drink...do you take your helmet in with you, leave on your bike or lock it up?
...I lock it up with a 'beener under the seat.
Excuse my ignorance, but I'm assuming you are referring to a caribiner for like mountain climbing...how do you lock it with that?
I was afraid someone was going to ask that. It's a bit difficult to explain.
You remove the seat, lace up your helmet, put a caribiner through the straps. The click the caribiner onto the frame right by the gas tank. Re-attach seat and all done. The caribiner and helmet cannot be removed without removing the seat.
I'll try and get a pic up later.
I usually lock it up to the bike if I am within eyesight of it. If I am going inside a mall or something, my tank bag doubles as a bookbag with the bottom compartment expanding specifially to carry a helmet. Works great!
