The Reaction 240 SL takes a deliberately minimalist approach in the name of performance. From the thinner handlebar and grips to the lightweight rigid carbon fork, we've sweated the details to make this a lightweight, fast, fun and safe bike for aspiring racers. A 10-speed Microshift transmission delivers crisp, accurate gear changes across a wide range. Light, powerful V-brakes offer plenty of stopping power. And confidence-inspiring, lively handling comes as standard. On your marks, get set...

Frame and equipment

We don't cut corners at CUBE. That's why the Reaction 240 SL uses the same kind of heat-treated 6061 aluminium tubes that you'll find in our performance adult bikes, as well as the same mechanical tube forming process to adjust tube shapes for the best combination of strength and weight. A replaceable derailleur hanger insures against expensive repairs in the event of minor mishaps, and there's plenty of clearance for wide tyres to ensure great grip, comfort and safety.
