Running 48:16 at the mo, but am in the process of building a new bike. Looking to spin just a little bit more as I'm riding through central London. As I'm getting a new crank and cog, can change either side. 48:18 seems popular, but worried it's too spinny. Maybe 46:16 would be better. Anyone have any suggestions? Obviously the crank size I want to get right, as I can change the cogs. 48T or 46T?
