I get the benefit of the smaller front sprocket should equal quicker acceleration, smaller rear sprocket for top speed argument, but why would you choose one of these gearings over the other??
| As you say this is the same ratio 3.2 and 3.21 respectively, so wouldn't make any difference to acceleration or top speed at rev limit, but with 15/48 you are running 4 teeth more than 14/45, so for the same length of chain the rear wheel will be 2 links closer to the swing arm pivot, (assuming there is enough adjustment) In theory, this shorter wheelbase will make the bike turn more quickly, but it will be less stable at high speed, and maybe lift the rear when hard on the brakes. I have 14/46 at the moment, Roxy has 15/46 both with 5 speed box, the consensus seems to be not to mess with sprockets too much . So what gearing do you all use and does anybody change gearing for different circuits, or is it not necessary ???? |
