Although we have a guide on How to Green your Outdoor Sports and one on Public Transportation, we're currently missing one specifically on Bicycling. So, while you're waiting for that guide to pedal past, you may wish to consult the Sierra Club's How Green is My Bike Ride? questionnaire.
Where the Q's run the gamut of:
"When my bicycle chain gets dirty...
- I toss my bike in the back of the car and head for the bike shop.
- I clean my chain with kerosene or another petroleum-based solvent.
- I clean my chain with a citrus solvent.
- Aren't bike chains supposed to be dirty?"
