Considering a sprocket change-now running a 520 conversion, 16 front and 43 rear. Would like to go to a 17 front/43 rear or 16 front/41 rear for highway performance. Any feedback?

 

i'd go with the 41 rear, 16 up front is pretty tight clearance for the chain as it is without goin to a 17. plus with a smaller rear thats less spinning weight, and the chain doesn't spin as fast for the same speed. im fixin to get me another rear hub off ebay so i can get a smaller sprocket and then it would be quick changes for different ratios.
