I recently added rollers to fall/winter training routine. My purpose is to improve my bike handling. So far, I've only put in a couple hours on them. I have difficulty with common tasks such as reaching for the bottle, checking my wrist HR monitor, wiping off sweat and adjusting the TV's volume control. I can accomplish all these tasks, but I'm sketchy. In low gears all bets are off and I can only manage to stay upright.

How do I become more proficient? More roller time, practice spinning in lower gears, what else? Will I naturally work through these difficulties with added time?
