The one thing I note about the Mango is the close spacing of the top and bottom ratios on the rear cassette. On the RT-58, I never use the smaller front chain ring because of the wider range of rear ratios. Shifting is pure joy.

You must never ride up any sort of hill, or are a lightweight with thighs of steel! Most rides I don't shift either (I can do my usual 15 mile loop on a SS), but I certainly wouldn't manage the Surrey Hills or even Richmond Park without! Be careful not to cross chain, i.e. big cog front and rear
