Adult Road Bike
In a double gear shift which gear do you change first?
I'm an adult beginner cyclist and a friend has loaned me her road bike to try. It has 2 on the crank and 9 at the back. I've been starting on the smallest crank wheel and working up through the gears. When I reach the top what should I do next? I don't want to damage her bike.
Don't worry ~ you're not going to damage the bike, but there are a couple of things you want to avoid...
Don't ride in gear combinations that put the chain in an exteme angle ~ large chainring and large cog, and small chainring and small cog. You should be riding with the chain somewhere in the middle of the the 9 gears on back. Select the chainring on the cranks that allows you to stay in that optimum combination.
Another thing to consider is your cadence ~ or how fast you are pedaling. You should be spinning the cranks anywhere from 70 to 90 RPM's. Select the gear combination that allows you to do that. This is why there are so many gears on today's bikes. There are only one or two tooth differences between gears which allows a cyclist to make subtle changes in order to maintain his or her spin.
Also, it is not necessary to go through all of the gears while you're riding. It's not like driving a car or riding a motorcyle ~ where you start out in first gear and then go to second, and so on.
This is how I ride ~ I start out on the small chainring with a gear selection that places the chain somewhere in the middle of the rear cassette. Once I get moving pretty fast, and where my spin is near the top of my desired RPM's, I shift to the large chainring and make whatever adjustments are necessary so that I can maintain my spin. I shift back down to the small chainring in the front before coming to a stop. Then I start the same way I did before, and then shift back to the large chainring. If I find that I have to keep making adjustments that bring me close to the large cog on the rear wheel, then I shift back down to the small chainring in front, and find a gear combination on the rear wheel that allows me to maintain my spin.
Hope that helps.
