Though, the one about the gear men use on downhills could be worded in a gender neutral way and still be funny.
I actually thought about that. It's a quote from Phil Liggett from the 1986 TDF:
"There goes Benard Hinault, in a gear most men use only on the downhills!"
I thought that since the "most men" part refers to the gear in use that it was gender neutral enough that I should keep to the exact words.
