| Let talk sprockets....
the problem w/ going down in the front is now you've go a big heavy chain that has to make a tighter turn.... think of how fast the chain is whipping towards the front sprocket... now it's gotta make a tighter turn once it gets there.
This change in direction creates a loss in power..... VERY miniscule, yes, but worth taking into consideration.... if you can get away w/ going to a bigger rear & getting the same ratio improvment w/o adding links (and weight) to the chain, do that. |
