You don't need any speed as I have been discovering after riding gears for a few days

.
Seriously though, what I dislike about all the modern groupsets is this insistence of having a massive jump between outer and inner chain rings. I have a new Ultegra on my geared bike and it is a 53 / 39, how I long for a
52 /42 or 52 / 40, even with a 12 x 25 on the back I was finding it difficult to select a comfortable gear. My old
52 / 42 / 32 triple was much friendlier and only ever used the granny in Cornwall.
