The gearing change you are recommending will give you a broader range of gears for more diverse conditions. The trade-off is that their will be a less smooth transition between gear changes. Its a good setup for varying terrain and speeds, but less efficient shifting if you plan to race it.
The new chain is needed and will need to be longer by about 8 links
When I ride my bike I feel free and happy and strong. I'm liberated from the usual nonsense of day to day life. Solid, dependable, silent, my bike is my horse, my fighter jet, my island, my friend. Together we will conquer that hill and thereafter the world.
