One known benefit of the freewheel swap was having the option to adjust gearing a bit. My son started spinning out the 14T freewheel this spring so I swapped in a 13T to help slow his legs a bit. Got him 2mph more on the flats! Still spins it out with even the slightest downgrade so I'm looking forward to getting him some real gears on his next bike.
