Do you have to pull links in order to put on a 12?

 

I run 12 44 and pull 4th really good up hills.

 

I know what you are talking about, but can you explain how that works to me? please[img]i/expressions/face-icon-small-happy.gif[/img]

Pretending that 1 tooth in the front is equal to 3 in the back, how is it that a 14/40 is better than a 13/37?

A Raptor with 14/40 gearring at 8,500RPM goes: 93.77
A Raptor with 13/37 gearring at 8,500RPM goes: 94.14

that should both be a 2.85 ratio

 

Ward 660 - you don't drop both at the same time. only one or, the other.

 

Did you figure those speeds mathamaticly? It seems you did because 13/37 is just a bit higher by .011.

The way I understand it is the smaller the sprocket and the tighter the radius the more the chain has to bend/work, taking away power.
Your chain and spockets usually last longer also if bigger.

 

The speeds came from a gearring calculator, but the ratio came from a sheet I have printed.


I understand what you are explaining. Thanks[img]i/expressions/face-icon-small-cool.gif[/img]

 

There is a ratio chart on renthal's web page. Gearing Ratios
