I’ve used these simple pant clips for the past 2 years. They are small, inexpensive and effective. They keep my pants from getting dirty from or torn in the chain of my bike. Their combination of simplicity and low price make them a great solution to a common biking problem.
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
