isitafox Posted February 8, 2014 Report Share Posted February 8, 2014 Assuming you're riding a 20" then ideally you want a 18t freewheel on the cranks and a 13t sprocket on the rear. Quote Link to comment Share on other sites More sharing options...
Martin Reynolds Posted February 8, 2014 Report Share Posted February 8, 2014 Assuming you're riding a 20" then ideally you want a 18t freewheel on the cranks and a 13t sprocket on the rear. His profile says hes 19/20, so i i'd suggest 12 Tooth rear sprocket Quote Link to comment Share on other sites More sharing options...
