Redchilli SR1 “Flamme Rouge”

Redchilli SR1 Flamme Rouge

The Smooth‑Riding Endurance Bike Designed for Comfort, Control, and Long‑Distance Performance

The SR1 Flamme Rouge is our top‑level endurance road bike — engineered for comfort, stability, and all‑day performance without sacrificing speed. Whether you’re heading out for a short, fast‑paced ride or an epic long‑distance adventure, the SR1 delivers a smooth, efficient, and confidence‑inspiring ride position that keeps you comfortable for mile after mile.

For the keen endurance rider, the SR1 offers a near race‑bike experience but with a more forgiving geometry and a carbon layup tuned for comfort. This reduces fatigue on longer rides while still giving you the responsiveness and efficiency you expect from a Redchilli. The semi‑aero tube profiles add free speed on the flats, while the specially shaped down tube, bottom bracket, and rear triangle help the SR1 climb with ease when the terrain turns challenging.

Endurance Comfort Meets Real‑World Performance
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.

Example bike builds

  • Hand‑built in Great Britain, with every SR1 assembled in Axminster, Devon for exceptional quality and attention to detail.
  • Toray T700/T800 carbon blend delivers the ideal balance of comfort, strength, and low weight for endurance riding.
  • Advanced 3D mandrel technology creates smoother internal walls, reducing wrinkles in the layup for improved strength and reduced weight.
  • One‑piece mould construction increases structural integrity and enhances stability across both the front and rear triangle.
  • Semi‑aero down tube adds free speed on the flats while maintaining the compliance needed for long‑distance comfort.
  • Full internal cable routing for a clean aesthetic and improved aerodynamic efficiency.
  • Box‑section rear triangle boosts torsional stiffness for efficient climbing and steady power delivery.
  • Rigorous testing ensures the SR1 meets and exceeds ISO 4210 standards.
  • Tyre clearance up to 700×32mm, giving you more comfort and confidence on imperfect roads and long‑distance routes.

  • Every SR1 build starts with understanding how you ride. As an endurance‑focused platform, comfort, stability, and long‑distance efficiency are central to the SR1’s design — and your custom build will reflect that from the very first conversation
  • You can choose between a one‑piece, fully integrated carbon handlebar for a clean, aerodynamic look, or a separate handlebar and stem for greater adjustability. Many endurance riders prefer the latter, as it allows finer control over bar rotation, lever angle, and hand position — all key to all‑day comfort. We’ll help you decide which option best suits your riding style and flexibility.
  • If you’re able to visit us in Axminster, we offer full bike‑fitting and saddle‑fitting services to ensure your SR1 is dialled perfectly to your position and riding style. And yes, we make an excellent cup of tea or coffee while we work through the details
  • If visiting isn’t possible, we can arrange a detailed video consultation, telephone call, or email discussion. This allows us to understand your fit, preferences, and performance goals so we can build your SR1 exactly the way you want it.
  • You can choose from our signature colour range, special finishes, or create your own custom design. It’s Your Bike – Your Way, and we’re here to help you bring your vision to life. (Additional charges may apply for full custom paint. Please enquire.)
  • After your consultation, we’ll provide a detailed build specification sheet along with 2–6 tailored build options, each with clear pricing. Build times vary depending on frame availability and paint choice: Signature Edition builds can be ready in as little as 7–10 days, while full custom paint typically takes 5–7 weeks. We’ll keep you updated throughout the process.
  • Once your frame and components are ready, your SR1 is hand‑built here in Axminster. You’re welcome to visit for a test‑fit before final assembly — and enjoy another cup of tea or coffee while your endurance machine comes to life.

SR1 Geometry Overview

  • Redchilli SR1 “Flamme Rouge”

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)

Fit Reassurance:

Contact us

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.
