hmmm what? I wear finger-less cushioned gloves with a rigid front fork in 100-degree weather, and my hands are no worse off than without them (except that they don't go numb with the gloves on, and it's easier to grip the bar ends). They still get hot, and they still get sweaty, either way.

I got back into cycling the first of May this year, and have worn my gloves on every single ride, over 350 miles, since then.
