I created this poll to help me decide what gearing I 'd need for my new light touring bike. The bike should be capable of light touring across the US, so I figure a 28c road tyres should be adequate. The load with rack and panniers inclusive should be <20lbs. On most routes where I cycle, a 34t front and 25tsprocket is all I need to climb hills. But touring with a 20lbs pound load is a different environment. My road bike weighs 7.9kg, while my cyclocross bike weighs 10.9kg without rack. If you need more information to cast your vote, please let me know. Thanks.
