After thousands of miles in the saddle and countless hours in my workshop, I've reached an inescapable conclusion: no single component impacts your ride like your saddle. Today, I want to get into what might seem like a mundane measurement but has genuinely changed cycling comfort—the 160mm saddle width.
The Silent Revolution Under Your Seat
Remember when cycling meant accepting saddle discomfort as part of the deal? When "breaking in" a new saddle actually meant breaking in your body through weeks of unnecessary pain? Those days are mostly behind us, and the rise of 160mm saddle options has played a big part in that shift.
But before we celebrate, let's look at why saddle width matters at all.
It's All About Your Bones (Yes, Really)
Your "sit bones" (ischial tuberosities, if you want the anatomy term) are the parts of your pelvis built to bear weight when you sit. These bony protrusions vary a lot between people:
- Men typically measure around 110–120mm between sit bones
- Women often measure between 120–140mm
- Individual variation goes well beyond these averages
Here's the critical insight the cycling industry missed for decades: your saddle needs to be wider than your sit bone measurement. The general rule is to add 20–30mm to your sit bone width for proper support. That's why 160mm saddles work so well for many riders—they support people with sit bones in the 130–140mm range, which includes many women and some men with wider pelvises.
The Painful History of Narrow Saddles
For decades, the cycling industry was stuck on narrow saddles (typically 130–140mm). That approach wasn't completely irrational—it came from a few factors:
- Competitive racers wanted minimal thigh interference during aggressive pedaling
- Weight savings (in a sport where every gram counts)
- Tradition and aesthetics that favored a sleek, minimalist look
But this one-size-fits-all approach ignored a fundamental problem: when your sit bones lack support, your weight shifts onto the soft tissues in your perineal area. That compression can reduce blood flow by up to 66% during riding—leading to numbness, discomfort, and potentially serious health issues over time. I've seen this firsthand in my fitting work with countless riders.
The Research That Changed Everything
Around the early 2000s, medical research started connecting saddle design to cyclist health. Dr. Irwin Goldstein and researchers at the National Institute for Occupational Safety and Health produced compelling evidence that traditional narrow saddles were causing real problems for many riders.
I've followed this research closely throughout my career, and the findings were impossible to ignore. Studies showed that proper saddle width dramatically reduced pressure on sensitive areas while improving blood flow and preventing nerve compression. This wasn't just about comfort—it was about cyclist health and the sport's sustainability.
How Do You Know If 160mm Is Right for You?
While 160mm has become something of a sweet spot, it's not universal. Here's my tried-and-tested guide to figuring out if it might work for you:
- Measure your sit bones: Most quality bike shops offer sit bone measurement. You can also DIY by sitting on corrugated cardboard and measuring the distance between indentations.
- Consider your riding position: More upright riders typically need wider saddles, while aggressive positions might work with slightly narrower options.
- Assess your flexibility: Less flexible riders often benefit from wider saddles with pressure-relieving cutouts.
- Test, test, test: The ultimate proof is in riding. Many shops have test saddle programs—take advantage of them before committing.
Beyond Width: The Complete Saddle Picture
I've focused on width, but modern saddle design includes several elements working together:
- Central cutouts or channels: These relieve pressure on soft tissues and can make a dramatic difference
- Variable padding density: Firmer under sit bones, softer in sensitive areas for optimal support
- Shell flexibility: Engineered to absorb road vibration without bottoming out
- Nose length and width: Affects how you position yourself during different riding scenarios
In my testing across various conditions, I've found that a well-designed 160mm saddle with these features can transform the ride, especially on longer rides where comfort issues compound over time.
Real World Success Stories
In my fitting studio, I've seen countless cyclists improve dramatically after switching to properly-sized saddles around the 160mm mark:
- A female mountain biker who accepted post-ride numbness as "just part of cycling" until she tried a 155mm saddle with a cutout—she called me a week later, overjoyed at the change
- A male road cyclist who solved persistent saddle sores by moving from 143mm to 158mm after years of unnecessary suffering
- A daily bike commuter who could suddenly ride comfortably without padded shorts after finding the right saddle width
The pattern is clear: riders who've suffered needlessly often find immediate relief with wider saddles that properly support their unique anatomy.
The Industry Catches Up
The good news is that virtually every major saddle manufacturer now offers options in the 155–165mm range. Some standouts from my testing:
- Specialized Power: Available in 143mm, 155mm, and 168mm widths with excellent pressure mapping
- Fizik Tempo Argo: Offered in 150mm and 160mm widths with a shortened nose for versatile positioning
- Brooks C17: A modern take on a classic design at 162mm width, perfect for commuting
- WTB Koda: Available in 142mm and 150mm widths with female-focused design features
These companies have embraced the research and responded with products that prioritize anatomical support alongside performance. I've watched this evolution unfold and tested each iteration as the industry improved.
The Future of Saddle Comfort
The 160mm shift is just the start of a more rider-focused approach to saddle design. The industry is moving toward even more personalized options:
- 3D printed saddles from companies like Specialized (Mirror Technology) and Fizik (Adaptive series) that create infinitely tailored support zones
- Advanced pressure mapping protocols that consider riding style, flexibility, and unique anatomy
- Adjustable systems like BiSaddle that let riders fine-tune width and shape for their specific needs
Having tested many of these innovations, I'm excited about where saddle technology is heading—toward solutions as individual as the riders themselves.
Bottom Line: Don't Suffer Needlessly
After years in this industry, watching technology evolve and working with riders of all levels, my most important advice is simple: don't accept discomfort as normal. If you're experiencing numbness, pain, or pressure on sensitive areas, your saddle is likely too narrow for your anatomy.
The 160mm width has become popular because it works for so many people who were previously underserved by traditional narrow designs. It represents cycling's evolution beyond a sport focused solely on racing to one that embraces comfort, health, and accessibility for all riders.
Have you made the switch to a wider saddle? I'd love to hear about your experience. And if you're still riding on a narrow perch, maybe it's time to consider if a 160mm option could transform your relationship with cycling.
