Since the introduction of the 9-tooth driver way back in 2003, we’ve seen the freestyle side of BMX adopt the 25-9 gear ratio as a bit of the standard, but there are still plenty of options and combinations that can change the way your bike feels, how fast you can go and more. Profile Racing released their latest “Tech Tip” that gives you some insight into how the gearing works and what a few of their riders run for combinations. You can check it all out over on the Profile Racing website — How Many Teeth Do You Need?
What combination do you run on your bike and why? Let us know in the comments below! We would love to hear what you have to say on the subject!
