"What Our Gearhead® Experts Are Saying:""I’ve used the Killawatt Resistance Unit on both gravel and road rollers, and it’s been a game-changer for indoor training. The magnetic resistance is buttery smooth and silent, letting me focus on cadence and power output without distraction. Plus, adjusting the resistance on the fly is intuitive—no tools needed. It’s perfect for everything from endurance intervals to sprints.""We love how the Killawatt Resistance Unit transforms a simple roller setup into a versatile training machine. This adjustable resistance unit pairs seamlessly with Kreitler Kompact and Standard rollers (not included), giving us precise control over our workouts. Its magnetic design ensures a smooth, quiet ride that won’t disturb housemates or neighbors during late-night training sessions. Whether we’re simulating a steep climb or dialing in consistent cadence work, the tool-free adjustments make customizing resistance quick and hassle-free."
