I installed a Brooks C17 Carved in black last night on my road bike (vintage steel Ciocc Designer 84 with modern Shimano 6700 components). It has about 2 inches drop to the bars. I previously had a Brooks Swift Titanium and it was too hard on my soft parts when rides got above about 35 miles.
For reference, I love my Brooks B17 that is on my upright touring bike/commuter (1988 Trek 520).
When installed last night (just riding around the block without cycling shorts), it felt hard on my sit bones. I leveled it a bit more and it felt much better on my ride to work this morning. No noticeable pressure on my soft bits.
I will update as I go on more rides.
