gearing gearing gearing!

i read of a guy running a 14t/49 he said it was 11% lower than stock . so my ? is y not just add a tooth or two to the stock 13t front ? y change the front ? maybe someone can fill me in on y he would do that.

A larger front sprocket is easier on the chain - whether it noticeably adds enough to chain life to make the change just for that, I don't know. Another reason is you could be thinking of having something like 14/47 for the equivalent of almost stock gearing for general running around and dirt road riding, and then swap down to a 12 tooth for some real tractor power when running gnarly singletrack.

If you add a couple of teeth to the stock - assuming you can get a 15 tooth in there - and don't change the rear sprocket, you're going to turn already tall gearing into REALLY tall gearing. Like, ridiculously tall.
