Ergon Size Guide
Ergon specialises in ergonomic bicycle accessories designed for optimal comfort and performance. The brand focuses on biomechanical efficiency, creating products that prioritise rider comfort through precise sizing and anatomical design. Ergon products are engineered for cyclists of all disciplines, from commuters to mountain bikers, with sizing systems tailored to individual body measurements rather than one-size-fits-all approaches. The brand's philosophy centres on personalised fit, ensuring that each accessory matches the unique proportions of the rider.
How to Measure
- For Saddle Sizing: Measure your sit bone width whilst seated. This is the distance between your two sitting bones (ischial tuberosities). You may find it helpful to sit on a firm surface covered with a soft material, then measure the distance between the two pressure points left behind.
- For Grip Sizing: Measure your hand circumference by wrapping a soft measuring tape around your palm at the widest point, excluding your thumb. Keep the tape snug but not tight.
- General Guidance: Take measurements in the evening when your hands and feet are at their largest due to natural swelling throughout the day.
- For Accuracy: Ask someone else to help you with measurements — results will be more precise than self-measurement.
- Between Sizes: If your measurement falls between two sizes, we recommend ordering the larger size for enhanced comfort during extended rides.
- Product-Specific Charts: Always consult the individual size chart for the specific Ergon product you are considering, as different product lines may have varying fit characteristics.

Product-Specific Guidance
Bicycle Saddles
Ergon saddles are categorised by sit bone width rather than traditional unisex sizing. Measure your sit bone width to determine whether you need a Narrow, Medium, or Wide saddle. This measurement is critical for long-distance comfort and proper weight distribution. The saddle wings and support structure vary in width to match your anatomy, ensuring pressure is evenly distributed across the contact area.
Handlebar Grips
Ergon grips (including the GP1, GC2, GR2, GC3, GE1, and GA1 models) are available in Small and Large sizes. The designation refers to grip thickness only; there is no difference in length or wing size between sizes. Small grips suit riders with smaller hands, women riders, those wearing padded gloves, and technical mountain bikers. Large grips are ideal for riders with larger hands, commuting, and city riding. Most riders in the North American market favour Small grips. Visit an Ergon dealer for hands-on comparison before purchasing.
General Fit Philosophy
Ergon sizing follows standard UK sizing conventions for most products. However, always check the product-specific size chart for each item, as different product categories may have distinct fit profiles. Read customer reviews for real-world fit feedback, and consider the item type (slim fit, regular fit, anatomical cut, etc.) when making your selection.
Sizing Tips
- Sit Bone Measurement is Key: Accurate sit bone width measurement is the foundation of saddle comfort. Invest time in measuring correctly, as even small errors can result in discomfort during rides.
- Hands-On Testing: Whenever possible, visit an Ergon dealer to handle grips and test saddles before purchasing. This tactile feedback is invaluable for determining the right fit for your hands and body.
- Size Up When in Doubt: If your measurement falls between two saddle or grip sizes, choose the larger option. Ergon accessories are designed to provide optimal support across a range within each size.
- Consider Riding Style: Your primary cycling discipline influences grip and saddle choice. Technical mountain bikers often prefer smaller, more responsive grips, whilst commuters benefit from larger, more supportive options.
- Layering and Glove Thickness: Account for padded cycling gloves and seasonal layering when selecting grip size. Thicker gloves may necessitate a Large grip for optimal control.
- Consult Product Reviews: Customer feedback on specific Ergon products often includes real-world fit observations. Use these insights alongside size charts for informed decision-making.
- Easy Returns: Many retailers offering Ergon products provide generous return windows (some up to 100 days). If you order the wrong size, returns are straightforward and hassle-free.
