Levers and Tools
Shouting this at a broken down rider when traveling at 25+ mph cusps on useless.
Out of ear shot, no wordy response will be heard. Trust me on this.
Having a bag under the saddle which is short of proper equipment leaves rider stranded, or nearly so.
There I was, friends rushing past, trying desperately to pry off my tire sans levers. Eventually, the task was completed.
Without the proper tools, a task can take forever. Simple and quick turns to painful, complicated, frustrating and slow.
When help is needed, be clear and concise.
