Redchilli GR1 Hors Route

The Versatile Carbon Gravel Bike Engineered for Adventure, Stability, and All‑Terrain Performance
If you want a bike that opens up new routes, new terrain, and new possibilities, the Redchilli GR1 delivers the perfect blend of speed, stability, and rugged versatility. Built around a full carbon frameset, the GR1 is lightweight, responsive, and engineered for riders who want freedom beyond the tarmac — without compromising performance.

Whether you’re tackling fast gravel, mixed‑surface endurance rides, or long days exploring new routes, the GR1 offers predictable handling, vibration‑damping comfort, and the durability you need to ride further. It’s a bike that feels fast on the road, capable on the rough stuff, and endlessly fun everywhere in between

Confidence, Control & Capability — Wherever the Ride Takes You
Every aspect of the GR1 has been engineered for stability and versatility. The optimised gravel geometry provides a planted, confidence‑inspiring ride on loose surfaces, while maintaining the agility and responsiveness Redchilli riders expect.

The full carbon frame and fork absorb vibration and keep handling precise, even when the terrain gets rough. Wide tyre clearance allows you to run larger tyres for grip and comfort, and multiple mounting points give you the freedom to carry bottles, bags, and adventure gear. Whether it’s a fast gravel spin, a day‑long adventure, the daily commute, or a relaxed ride with friends — the GR1 is ready. In fact, it’s simply gravelicious….

Every GR1 custom build begins with choice. You can select our fully integrated one‑piece carbon gravel cockpit — the Redchilli IRB‑G — or choose a separate handlebar and stem for maximum adjustability in bar rotation, flare, and lever positioning. Because gravel riding demands comfort, control, and confidence across varied terrain, we’ll help you find the cockpit setup that feels perfect for your style of riding.
If you’re able to visit us in Axminster, we offer full bike‑fitting and saddle‑fitting services to ensure your GR1 matches your flexibility, preferred riding position, and the type of terrain you enjoy most. And of course, we’ll make you 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 GR1 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 GR1 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 adventure‑ready machine comes to life.

GR1 Geometry Overview
The GR1 is built around an adventure‑ready geometry that prioritises stability, comfort, and control across unpredictable terrain. A generous wheelbase, relaxed head angle, and balanced stack height keep the bike composed on loose gravel and demanding off‑road sections, while still offering efficient on‑road performance. It’s a geometry that encourages exploration — confident, smooth, and capable mile after mile.

Key Geometry Traits
– Confident stability thanks to long wheelbase and 435mm chainstays
– Predictable handling from relaxed head‑tube angles (70.5°–72°)
– Balanced endurance fit with generous stack across all sizes
– Efficient power transfer supported by consistent reach progression
– Smooth, composed ride feel on loose and technical terrain

Recommended Rider Height
Size 49 — 5’1″–5’4″ (155–163 cm)
Size 52 — 5’4″–5’7″ (163–170 cm)
Size 54 — 5’7″–5’10″ (170–178 cm)
Size 56 — 5’10″–6’1″ (178–185 cm)
Size 58 — 6’1″–6’4″ (185–193 cm)

Fit Reassurance
Not sure which size is right? We’ll confirm your perfect fit during your custom build consultation. Our fit philosophy ensures your position is optimised for power, comfort, and control, whether you prefer an aggressive race stance or a more endurance‑focused setup.

The GR1 is ideal if you want a bike that can do it all — from everyday riding and social group spins to exploring gravel tracks, bridleways, and mixed‑terrain routes. Its balanced geometry and confident handling make it just as comfortable on long road miles as it is on loose, technical surfaces. If you’re looking for a versatile, smooth‑riding frameset that encourages adventure without sacrificing speed or efficiency, the GR1 is the perfect choice.
