For something we literally sit on for hours at a time, bicycle saddles remain surprisingly misunderstood. After 25 years fitting riders of all levels, I've watched countless cyclists transform their riding experience with one simple change-finding the right saddle width. And there's a reason 160mm options have become so prevalent in recent years.
If you've spent any time browsing your local bike shop's saddle wall or scrolling through endless options online, you've likely noticed numerous 160mm width saddles from nearly every manufacturer. This isn't random-it represents one of cycling's most significant but quietly revolutionary developments in rider comfort.
The Anatomy of Comfort: Why Saddle Width Matters
Let's talk anatomy for a moment (I promise to keep it PG). When properly seated on a bicycle, your weight should primarily rest on two bony protrusions called your "sit bones" or ischial tuberosities if you want to impress your riding buddies. These bones are part of your pelvis and evolved specifically to bear your seated weight.
Here's the crucial part that many cyclists overlook: the distance between these sit bones varies significantly from person to person:
- Most men's sit bones measure between 100-140mm apart
- Most women's sit bones typically range from 110-160mm apart
When your saddle is too narrow (as many stock saddles are), your sit bones hang off the edges, forcing soft tissues to bear weight they were never designed to handle. This leads to numbness, pain, and potentially even long-term health issues that can take you off the bike altogether.
A properly sized 160mm saddle provides enough surface area to support many riders' sit bones completely while remaining narrow enough to allow efficient pedaling without thigh interference. I've seen this measurement work remarkably well as a starting point for approximately 40% of male riders and well over half of female cyclists I've fitted.
From Suffering to Science: The Evolution to 160mm
I still remember the dark ages of cycling when we simply accepted discomfort as part of the sport. The old-school mentality of "toughen up" meant many riders were using painfully narrow saddles in the 130-145mm range regardless of their actual anatomy. I was guilty of this myself, riding a needle-thin racing saddle because that's what the pros used.
Around the early 2000s, several game-changing developments converged to challenge this thinking:
- Medical researchers published concerning studies about the relationship between improper saddle fit and circulatory/nerve issues
- Pressure mapping technology allowed us to actually visualize where riders were experiencing pressure
- Women's participation in cycling grew, highlighting the inadequacy of narrow saddles for many female riders
In 2004, Specialized made waves with their Body Geometry saddle line featuring multiple width options, including 160mm versions. Their research revealed that approximately 40% of male riders and 60% of female riders benefited from saddles 155mm or wider. I was skeptical until I tried one myself-the difference was immediate and profound.
By 2010, most major manufacturers had followed suit. The industry had finally acknowledged what many uncomfortable riders had known all along: one size does NOT fit all posteriors!
The Performance Paradox: Wider Can Be Faster
Here's where things get interesting for the performance-minded cyclists I work with. Conventional wisdom once insisted that serious cyclists needed narrow saddles for maximum performance. After all, less material means less weight and less potential for chafing, right?
The data tells a different story, and I've seen it firsthand in my coaching practice.
Professional cycling teams using properly fitted 160mm saddles have documented improved sustained power in time trials and reduced fatigue in multi-stage races. Several WorldTour teams now use 160mm saddles for their riders, particularly time trial specialists who maintain aggressive positions for extended periods.
Think about it: when you're comfortable, you can:
- Maintain your optimal position longer
- Focus on producing power rather than shifting to relieve pressure
- Reduce energy wasted on unnecessary movement and adjustments
As Jan Frodeno, Olympic gold medalist and multiple Ironman World Champion, noted after switching to a wider saddle: "The stability I get from a properly supporting saddle means I can stay in my aero position longer without compromising power." I've seen similar results with amateur racers who initially resisted wider saddles for fear of looking "less pro."
Finding Your Perfect Fit: Is 160mm Right for You?
While 160mm has emerged as something of a "goldilocks" width for many cyclists, the only way to know for sure is to measure your sit bones. Here's a simple at-home method I recommend to cyclists between professional fittings:
- Place a piece of corrugated cardboard on a hard chair
- Sit on it while leaning forward slightly (simulating riding position)
- Stand up and look for the two indentations made by your sit bones
- Measure the distance between the center of these indentations
- Add 25-30mm to this measurement for your ideal saddle width
For more precision, many bike shops offer sit bone measurement services using pressure-sensing pads. I use a dynamic fitting system that allows riders to test different widths while monitoring pressure distribution in real-time-the results often surprise even experienced cyclists.
Remember: your ideal saddle width depends not just on sit bone width but also your riding style and flexibility. More aggressive, forward-leaning positions often work with slightly narrower saddles than upright comfort positions. This is why many riders who toggle between road and gravel bikes might prefer different saddle widths for each.
Beyond Width: Modern Saddle Innovations
While width is crucial, today's best saddles incorporate several other anatomical considerations I look for when fitting clients:
- Central cutouts or channels to relieve pressure on soft tissues
- Varied padding densities across different zones of the saddle
- Shell flexibility tuned to flex in certain areas while providing stability in others
- Nose width and shape designed for specific riding positions
Some cutting-edge companies like BiSaddle have even created adjustable-width systems that allow riders to modify saddle width from approximately 100mm to 175mm. I've tested these extensively with clients, and interestingly, their data shows that over 45% of customers initially set their saddles between 155-165mm-further confirming the biomechanical relevance of this width range.
The Future of Sitting: Where Saddle Technology is Heading
Having attended industry trade shows and worked with prototype saddles for decades, I can tell you saddle technology is evolving rapidly:
- 3D-printed adaptive cushioning from companies like Specialized (Mirror technology) and Fizik (Adaptive line) creates variable support zones within a single saddle
- Smart saddles with pressure feedback that can coach you into optimal positioning
- Completely personalized designs based on 3D scans of your anatomy
- Integrated biometrics that might someday allow saddles to adapt to your changing needs throughout a ride
These technologies aren't making the 160mm reference point obsolete-rather, they're building upon the biomechanical understanding that made this width significant in the first place. I've tested early versions of several of these technologies, and the future looks promising (and comfortable).
Conclusion: Finding Your Perfect Perch
The prevalence of 160mm saddles represents cycling's evolution from tradition-bound suffering toward evidence-based comfort optimization. This dimension has become a sweet spot that balances anatomical support with performance efficiency for many riders I work with.
If you're still riding whatever saddle came with your bike, or struggling with discomfort on long rides, a proper saddle fitting might be the single most important upgrade you can make. I've seen it transform rides for cyclists who were ready to give up the sport due to discomfort.
Your perfect saddle isn't about prestige, price, or what the pros are using-it's about finding the shape that lets you forget you're sitting on anything at all. For many riders, that journey leads to a 160mm saddle that perfectly bridges the gap between performance and personalization.
After all, cycling should be about enjoying the journey, not enduring it. And that starts with finding your perfect perch.
