I do have a gym routine etc so ide rather have a stiffer gearing is possible eg 18:12 on a mod is what I used to run. I think ile get 170mm cranks with a 15t cog on the rear and run the 18t tensile freewheel on the front...
As the wheel im hopefully buying has a 16t cog on the rear and i have cranks to buy ile buy 175mm cranks and ile use the 16t cog allready with the wheel then or should I get shorter cranks?
