saracen1989 Posted August 3, 2010 Report Share Posted August 3, 2010 (edited) Whats the best ratio to have 18t freewheel on the rear and a 12t fixed sprocket on the front? Edited August 3, 2010 by saracen1989 Quote Link to comment Share on other sites More sharing options...
Revolver Posted August 3, 2010 Report Share Posted August 3, 2010 The other way around, 18t front, 12t rear. Quote Link to comment Share on other sites More sharing options...

The 18t freewheel goes on the cranks, any 12t screw on sprocket will do for the rear Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted August 3, 2010 Report Share Posted August 3, 2010 As said, you want the 18t up front, and 12t on the rear! If you're somehow stuck with the 18t on the back, then I think 24t would be the closest. That's what my old T-Bird had back in the day, and that seemed alright to me!

CC12345678910 Posted August 4, 2010 Report Share Posted August 4, 2010 18.12 Is the ratio you really want. It is standard on any bike >£500 4 a reason. If you have a rear freewheel, drop to 16t, it will have the same feel. Quote Link to comment Share on other sites More sharing options...
