99% of the time it's in a bag, again I ride natural or in nice places where people don't steal my shit. When it's not in the bag it's in my car and I only have my single car key on me.
Back in the day i smashed about 5 or 6 phonescreens by having them in my pocket, luckily they were 3310s and the like. Bikes were shorter then so I used to hit my thigh on the bars all the time. Think my prefered pocket was a rear deep jean pocket, but also used the front on occasion.
