Orbea Road & Gravel Bike Size Chart

Orbea's road and gravel bikes are engineered for a perfect blend of lightweight performance, aerodynamic efficiency, and long-distance comfort. This category is home to some of the most desirable bikes in the world, including the iconic lightweight climbing Orca, the aero Orca Aero, the comfortable endurance Avant, and the versatile all-road Terra gravel bike. These models all use a numeric sizing system (e.g., 47, 49, 51) which allows for a very precise fit. Getting this right is crucial for maximizing power transfer and comfort, whether you're racing or on a multi-day bikepacking trip. This master table is your primary reference for any search for an Orbea Orca size chart or Orbea Terra size chart.

Choosing Your Orbea Road Bike Size

While the chart below provides an excellent starting point, your final choice may be influenced by your flexibility and riding goals. For a pure race bike like the Orca, riders often seek a lower, more aggressive position and might choose the smaller of two potential sizes to achieve a greater saddle-to-bar drop. For an endurance bike like the Avant, with its more relaxed geometry, comfort is key, and riders will typically be very happy with their recommended size. The Terra gravel bike has a geometry that balances road speed with off-road stability, making the recommended size a perfect blend for most riders.

Applies to: Orca, Orca Aero, Avant, Terra, and the Gain E-Road/Gravel bike.

Orbea Performance Mountain Bike Size Chart

Orbea's performance mountain bike lineup is born from a deep racing heritage and is built to conquer every part of the mountain. This category includes the enduro-racing Rallon, the do-it-all trail master Occam, the lightning-fast XC Oiz, the aggressive hardtail Laufey, and the XC-focused hardtail Alma. These bikes feature modern, trail-focused geometry and share a common S, M, L, XL sizing structure designed to provide a balanced and confidence-inspiring ride.

Rallon, Occam, Oiz, Laufey & Alma Sizing

This is the definitive sizing chart for Orbea's core mountain bike range. Whether you need an Orbea Rallon size chart for your next enduro race, an Orbea Occam sizing guide for all-day trail adventures, or an Orbea Oiz size chart for the XC start line, this is the correct reference. Due to their progressive geometry, if you are between sizes, consider sizing down for a more playful bike or sizing up for maximum high-speed stability. This is especially true for the Rallon and Occam.

Applies to: Rallon, Occam, Oiz, Laufey, Alma, and their E-Bike equivalents (Wild, Rise, Urrun).

Beyond the Charts: A Deeper Look at Orbea's Geometry

To truly understand "what size Orbea bike do I need?", it helps to look beyond the basic height recommendations and delve into the world of frame geometry. These precise measurements are the secret sauce behind Orbea's acclaimed ride quality. Understanding a few key terms will empower you to make the most informed decision, especially if you find yourself between sizes.

Key Geometry Terms Explained

• Reach: This is the horizontal distance from the center of the bottom bracket to the center of the head tube. It's a key indicator of how long the bike will feel when you're standing on the pedals. Longer reach numbers (found on bikes like the Rallon) provide more stability at speed.
• Stack: This is the vertical distance from the bottom bracket to the top of the head tube. It determines how high the handlebars are. A higher stack (found on the Avant endurance bike) provides a more upright, comfortable riding position.
• Head Tube Angle: A 'slacker' (lower number) angle pushes the front wheel further out, increasing stability on descents. An enduro bike like the Rallon has a much slacker head angle than an XC bike like the Oiz.
• Seat Tube Angle: A 'steeper' (higher number) angle positions the rider more directly over the pedals, which is a huge advantage for efficient climbing on modern mountain bikes like the Occam.

The Orbea MyO Program: The Ultimate in Custom Fit & Style

One of Orbea's most significant features is its MyO (My Orbea) customization program. For many high-end models, MyO is a powerful tool that goes beyond just sizing. It allows you to become part of the design process. While it doesn't change the frame size itself, it's crucial for fine-tuning your fit. Through the online MyO platform, you can not only choose from millions of custom colour combinations but also select specific component sizes. This means you can order your new Orbea Orca with the correct stem length, handlebar width, and crank arm length for your body, all at no extra cost. This level of personalization ensures that your bike arrives with a near-custom fit, perfectly complementing the frame size you've chosen from the chart.

Orbea E-Bike Sizing (Rise, Wild, Gain, Kemen)

Orbea has been a leader in the e-bike revolution, particularly with its lightweight Rise and Gain models. The good news is that sizing an Orbea e-bike is straightforward: they follow the exact same sizing charts as their non-electric counterparts.
The lightweight trail e-bike, the Orbea Rise, uses the Performance Mountain Bike chart, just like the Occam. The full-power enduro e-bike, the Orbea Wild, also uses that chart, just like the Rallon. The sleek e-road bike, the Orbea Gain, uses the Road & Gravel chart. The versatile trekking e-bike, the Kemen, uses the Sport & Urban chart. The main difference is the ride feel; the lower center of gravity from the motor and battery provides immense stability, which might influence your decision if you are between sizes.

Frequently Asked Questions About Orbea Sizing

What should I do if my height is between two sizes?

If you're on the border between two sizes, your personal preference and riding style should be the deciding factor. For mountain bikes, sizing down will give you a more playful and agile bike, while sizing up will provide more stability at speed. For road bikes, sizing down can allow for a more aggressive, aerodynamic position, while sizing up might offer a more relaxed fit. A test ride at a local Orbea dealer in the UK, from Bournemouth to Aberdeen, is the best way to make the final call.

Does Orbea make women's-specific bikes?

Orbea focuses on creating unisex frames with an extensive range of sizes and geometries that are designed to fit the vast majority of riders, regardless of gender. They believe that with the right frame size and component choices, they can achieve a perfect fit for anyone. Their MyO program is key to this, allowing any rider to select components like shorter stems or narrower handlebars to tailor the bike's fit to their specific needs.

How does Orbea sizing compare to other brands like Trek or Specialized?

Orbea's sizing is generally consistent with other major brands like Trek and Specialized. A "Large" from Orbea will fit a similarly sized rider as a "Large" from those brands. However, the bike's 'feel' will differ due to Orbea's unique geometry philosophy. Their mountain bikes often have a very balanced feel, while their road bikes are known for being exceptionally lightweight. You should always use the official Orbea size chart as your primary guide and not assume a size from another brand will transfer perfectly.
