It's a beautiful bright and sunny day in San Francisco, perfect weather for a bike ride up to Coit Tower in Telegraph Hill. And although the entire ride may be an uphill battle, getting back down can be equally as trying. Imagine the victory of bombing down that hill, and reaching for the brakes, only to realize that there are none on your bike. It sounds like a nightmare for some, but a dream come true for others.

Dylan Bigby is one of many daredevils in The City, dedicating his daily ride to the tune of having absolutely no brakes or gears, also known as a fixed gear. Riders must swing the back tire of the bike into a seemingly perpendicular position in order to skid to a stop, and although it may sound dangerous, it is also wasteful.

"You know it wastes your wheels, but you're doing it because you want to do it," Dylan explains.

Think about the amount of tires a rider goes through in a month, having to replace the rear one often because a thin layer of the tire rubs off into the asphalt after every skid. Not to mention the absurd amount of riders who own fixed gear bicycles in this city. It's about time someone decided to do something about it.

"Feeling guilty that I was wasting tires so much, I wanted to do something with them," Bigby said.

What is thin, circular and a practical garment that tires can be constructed into? Belts.

Alas, the conception of the tire belt, or "Re-Tired" belts as Dylan calls his up and coming line.

After a period of trial and error, mixing Velcro with brass buttons as closures, and struggling with supply of tires and demand for his belts, Dylan is looking to expand his production process in order to keep sales at an all time high - in such boutiques as RAG Co-op in Hayes Valley, and his blogspot website.

Dylan's environmental knack, if you will, does not end at Re-Tired belts. He is a veteran when it comes to green living, modeling his daily life in efforts to eliminate the size of his carbon footprint, by using one reusable handkerchief, a refillable water canteen, or set of bamboo utensils.

"There's a lot of things you can do that are little, but if you think about how many times you do that a year, a semester, even in a day, if you were to keep all the stuff you were about to throw away, there's so much, " says Bigby.

Waste accumulation is the premise behind his and fellow classmate Andrew Perry's environmental consulting brainchild, G-rock. What started out as a composting facility in the Bay Area, quickly turned into bigger projects such as the Indio International Tamale Festival in Indio, California.

There, and in other instances, G-rock's job is to "educate people about what is compostable, what is recyclable, and why it's important to compost, and why everything isn't just trash."

Thanks, Dylan, for your efforts in becoming the greenest man alive!
