If you bike a lot (and you probably do) then the learning curve on rollers is gonna be pretty short. I've been on some for about 20 minutes total and it was pretty smooth. You just gotta embrace the wobble.

And Today I....and some family members were playing with a cousin's rollers in the basement and my 15 year old cousin who doesn't own a road bike and has never done this was a ****ing prodigy. Several seconds of wobbly learning and he's good. Another couple minutes and he's just cruising, no hands, drinking a Mountain Dew for 10 minutes. Haha. It was incredible. And soul-shattering.
