ExtraLite QRC3S – The Lightest High-Stiffness Single Chainring Crankset on the Planet. 349g of pure Italian obsession. When every gram and every watt counts, the QRC3S delivers. This is not another lightweight crank — it's a masterpiece of 5-axis 3D CNC machining that gives you class-leading stiffness at a weight most carbon cranks can only dream of. Insanely light at 349g (complete with integrated spider, 30mm axle, and hardware) — save serious rotating weight and feel the difference on every climb and acceleration. Exceptional stiffness — Proven in independent testing to rival much heavier cranks. You get immediate, direct power transfer with virtually zero flex. Narrowest Q-Factor (142mm) — Better aerodynamics, more natural pedaling stance, and improved power delivery. Integrated 110mm BCD spider with captured female bolts — Clean, ultra-strong single ring setup. Mount any standard 110 BCD chainring with perfect alignment. Hollow 3D CNC crank arms — Sculpted for maximum strength-to-weight and stiffness. Every gram is intentionally removed, every curve engineered for performance. 30mm oversized axle — Rock-solid interface that eliminates flex and ensures legendary durability. 100% Made in Italy — Precision engineered by Extralite since 1995. This is the choice of serious weight weenies, gravel racers, and climbers who refuse to compromise. Imagine throwing down hard on a climb and feeling nothing but instant response — no twist, no lag, just pure power transferred to the road. That’s what the QRC3S gives you. It’s the crankset for riders who count grams like accountants count cents. For those who’ve tried everything and still want more. For the ones who know that in the final 200 meters, those saved grams and that extra stiffness are what separate the podium from the pack.
