Redchilli SR1 “Flamme Rouge” Frameset

Redchilli SR1 Flamme Rouge

The Smooth‑Riding Endurance Platform Built for Comfort, Control, and Long‑Distance Performance

If you want a premium endurance bike built around your exact fit and riding style, the Redchilli SR1 Frameset gives you the same smooth, stable, long‑distance performance as our complete SR1 — now with the freedom to create your perfect custom build. Engineered for comfort, efficiency, and all‑day control, the SR1 frameset is the ideal foundation for riders who value a refined, confidence‑inspiring ride.

The SR1 is our endurance‑tuned road platform — designed for riders who want a fast, responsive bike that remains comfortable over long distances. Whether you’re transferring components from your current bike or planning a full bespoke build, the SR1 frameset delivers a smooth, compliant ride feel, stable handling, and balanced stiffness for efficient power transfer.

Every element of the SR1 chassis has been developed to enhance comfort, stability, and long‑distance efficiency. The endurance‑tuned geometry creates a relaxed yet performance‑focused riding position, reducing fatigue on longer rides while maintaining precise handling on varied terrain.

Semi‑aero tube shaping adds free speed on the flats, while the specially engineered down tube, bottom bracket, and rear triangle deliver responsive acceleration and confident climbing. The result is a frameset that feels smooth, stable, and efficient — mile after mile.

It’s the ideal choice for riders who want comfort, stability, and performance without replacing parts they already love.
  • Professional Component Transfer Service
    Prefer us to handle the build? Simply bring us your existing bike and we’ll transfer your components with the same precision and care we apply to every Redchilli build. We ensure everything is fitted, aligned, and performing exactly as it should.

To guarantee perfect compatibility and performance, we’ll also identify any components that may need updating — such as bottom bracket or headset. Our goal is to make your transition to the SR1 Frameset seamless, efficient, and fully optimised.

SR1 Geometry Overview

  • Redchilli SR1 “Flamme Rouge” Frameset

The SR1 is built around an endurance‑tuned geometry designed to keep you comfortable, stable, and efficient on long‑distance rides. A slightly taller stack and shorter reach create a more relaxed position that reduces strain on the back, neck, and shoulders — ideal for sportives, gran fondos, and all‑day adventures.

The wheelbase and front‑end geometry are optimised for predictable, confidence‑inspiring handling on varied terrain, from smooth tarmac to rougher country lanes. The carbon layup is tuned to absorb road buzz without feeling soft, giving you a smooth, composed ride that still responds when you put the power down.

Whether you prefer a more upright endurance position or a slightly sportier setup, the SR1’s balanced geometry gives you the flexibility to dial in a fit that suits your riding style and long‑distance goals.

Key Geometry Traits:

  • Endurance‑focused fit for long‑distance comfort
  • Stable, predictable handling on varied terrain
  • Slightly taller head tube and shorter reach for reduced fatigue
  • Balanced stiffness for smooth, efficient power delivery
  • Optimised wheelbase for confidence on descents and rougher roads

Size 44 — 4’7″–5’0″ (140 – 152cm)
Size 47 — 5’0″–5’3″ (152 – 160cm)

The SR1 is ideal if you want a fast, efficient road bike that prioritises comfort and stability over long distances. Its endurance‑tuned geometry reduces fatigue on the back, neck, and shoulders, making it perfect for sportives, gran fondos, and all‑day adventures.

If you ride on a mix of smooth tarmac and rougher country lanes, the SR1’s compliant carbon layup and stable handling will keep you confident and comfortable throughout. It’s also a great choice if you prefer a slightly more upright position or value adjustability in your cockpit setup.

The SR1 still delivers the responsiveness and efficiency you expect from a Redchilli, but with a more forgiving ride feel than our FR‑series bikes. If you want a bike that’s fast, smooth, and built for real‑world roads, the SR1 is the perfect match.

If you’re unsure whether the SR1 or another model suits you best, we’ll talk through your riding style, goals, and fit during your custom build consultation to ensure you choose the right bike.
