This may be a simple question but I all ways get a different answer ever time I ask..
The bigger the rear sprocket = ? more top speed or what?
How about the smaller the rear sprocket (less teeth)... what good does that do.
Right now I think mine is 41 teeth..Whats this for.
Is there a big difference between 40 teeth and 41 teeth because I have both laying around the garage...
thanks guys

 

Bigger in front faster mph
Bigger in back slower mph
For every three tooth change at rear=1tooth at front
ex.14-43=13-40

 

lets assume that the front sprocket size stays the same... and I only change the rear sprocket

 

smaller rear makes the top speed faster, the bigger it is, it has bigger acceleration. the smaller, the faster. for front, the bigger the higher top speed. and smaller, better acceleration. when you change the rear sprocket, 1 or 2 teeth doesnt make too big of a difference. but when you change the front, you notice one tooth or 2 difference a lot more. like, lets say you have a 15 up front, and 41 in rear, and it went 70. you go to a 40 in rear, it will go about 72. there is a calculator at go to blue trax. it is blue trax.com, but add another "x."

 

Bigger front sprocket- Less accel, more top speed.
Smaller front sprocket-more accel, less top speed.

Bigger back sprocket-More accel, less top end.
Smaller back sprocket- More top speed, less accel.

 

Check out the ratio chart at www.sidewindersprockets.com. -or- Simply divide the rear # of teeth by the front # of teeth to get your ratio (#rear/#front). when you change the number of teeth on the front or rear, the ratio changes. If that ratio increases - less top speed, more "grunt". if it decreases - more top speed, less "grunt".

It's all in the numbers.....

 

great...thnx for the info...!

 

If you have the power to pull a taller gear then you will accelerate faster. Theres nothing you can say to make me change my mind about that.

 

A agree. Also, if you gear for more top speed, and can't PULL the gearing, one could actually loose top speed..[img]i/expressions/face-icon-small-wink.gif[/img].
