Frequently Asked Questions (FAQs)
1. What size sprocket makes you go faster?
To increase acceleration but decrease top speed, opt for a bigger rear sprocket or a smaller front sprocket. Conversely, a smaller rear sprocket or a bigger front sprocket will reduce acceleration but increase top speed.
2. Which sprocket wears faster?
The front sprocket tends to wear about twice as fast as the chain and three times as fast as the rear sprocket. However, with alloy sprockets, the wear rate may vary.
3. Is a steel or aluminum sprocket better?
Steel sprockets generally outlast 7075 aluminum sprockets by three times and also contribute to the longevity of the chain. Although steel sprockets are heavier, some options are only half a pound heavier than 7075 aluminum sprockets and half the weight of typical steel sprockets.
4. Do I need a bigger or smaller sprocket to go faster?
For better acceleration at the expense of top speed, opt for a smaller front sprocket and/or a bigger rear sprocket. This combination results in a higher final drive ratio, while a higher initial acceleration can be achieved by using a lower final drive ratio.
5. What does going up 1 tooth on rear sprocket do?
Increasing the rear sprocket by one tooth will result in noticeable changes, such as improved acceleration. To ensure optimal performance, it is recommended to also replace the chain and consider changing the front sprocket.
6. Is it better to change front sprocket or rear sprocket?
Changing the front sprocket and rear sprocket have opposite effects on gearing. Adding teeth to the front sprocket increases gearing, while adding teeth to the rear sprocket decreases gearing. Similarly, reducing teeth on the front sprocket decreases gearing, while reducing teeth on the rear sprocket increases gearing.
7. Should I size up or down sprocket?
To increase speed and decrease the final drive ratio, you can gear up by using a smaller rear sprocket or a larger front sprocket. On the other hand, to reduce speed and increase the final drive ratio, you can gear down by using a larger rear sprocket or a smaller front sprocket.
8. What sprocket is best for torque?
A smaller front sprocket increases the leverage of the engine to turn the wheel. This results in higher torque at the wheel, leading to faster acceleration. Therefore, opting for a smaller front sprocket or a larger rear sprocket can be beneficial for torque.
