bigamac Posted January 19, 2009 Report Share Posted January 19, 2009 It will just change your ratio, the higher tooth sprocket the higher the gearing.What are you planning to change it to? Quote Link to comment Share on other sites More sharing options...
psycholist Posted January 19, 2009 Report Share Posted January 19, 2009 A bigger front sprocket will give a higher gear, a bigger rear sprocket gives a lower gear. If you don't get gear ratios try thinking about them in terms of how much chain the sprocket moves, so a 18T front sprocket in one turn of the cranks moves the chain forward 18 rollers. If the rear is a 12T then this sprocket has to be driven on 18 roller's worth of chain too. 12 rollers of chain moved will cause a complete turn of a 12T sprocket, so it makes sense that the gear ratio is 18/12 = 1.5, this means the rear wheel turns 1.5 times for each turn of the pedals. If you want a higher gear change to a smaller sprocket at the back, if lower use a bigger rear sprocket. Quote Link to comment Share on other sites More sharing options...
Fvil Posted January 19, 2009 Author Report Share Posted January 19, 2009 so it will be more effort to have a sprocket with more teeth on the rear? Quote Link to comment Share on other sites More sharing options...
