sandeeebeach219 Posted August 7, 2010 Report Share Posted August 7, 2010 Hey I'm soon getting a freewheel, fixed sprocket and cranks, and was just wondering what the best gear ratio for my mod bike is? I was thinking 18T front and 13T back. What do you think? Thanks Quote Link to comment Share on other sites More sharing options...

Luke Dunstan Posted August 7, 2010 Report Share Posted August 7, 2010 I went from a 13 to a 12, made a nice difference. Quote Link to comment Share on other sites More sharing options...
