Isn't this why the flip-flop hub was invented? I'm running a 49t chainring with a 20t cog (66") on one side and a 18t on the other (73.5") then a set of track wheels with a 15t cog (88.2").
For the winter I've leave it with 66", I find it perfectly useable outside of central London: an average of around 95 rpm gives a speed of 30 kph, which I very rarely average above on a normal ride.
Well yes but my plan is to buy a 49t run 17t one side and 15t the other. An every day ratio and a track / TT ratio. I won't be buying a new set of wheels for racing until I know I am going to do it regularly. AS for my every day ratio my commute takes me from stoke newington to Northwick park, so i really am on open roads most of the time anything sub 70 would be far too spinny.
Any way the point of all this for any one trying to decide what ratio to run is to run whateverthefuckratioyouwanna
