I've had this gearing for some time now. I'm thinking I may not be cut out for 48/16 and maybe need to spin a little more. I'll pick up a cog from the LBS tomorrow. A buddy of mine also just offered me a 46t ring for free, so that's an option as well. I'll play around a bit with my ratio. Hopefully it will be a fun learning experience.
always go up, not down, to achieve the proper gear inches. the higher the number of teeth, the less wear. and try to go all even as well. read up on what sheldon brown wrote on the subject.
you just need a 18t cog in the back for approx. 70 GI w/ 23s.
