Ever notice how often 160mm pops up when you're shopping for a bike saddle? In the endurance, gravel, and everyday cycling world, 160mm-wide saddles are everywhere. You'll spot them in bike shops and on spec lists from major brands. But have you ever stopped to wonder why? And more importantly, is this so-called “perfect width” what your body actually needs?
It's easy to assume design choices like this are rooted in deep science. But the real story behind the rise of the 160mm saddle is far more interesting—and telling. Let's take a closer look at how this size became the industry's sweet spot, why it might be holding us back, and what the future holds for saddle comfort and customization.
The Story Behind the 160mm Saddle
The dominance of the 160mm width didn't come from thin air. In the early days, saddle width was mostly dictated by what worked best with natural leather—the starting point for many iconic models like the Brooks B17. These early saddles hovered around 160-170mm, largely thanks to material limitations and a dash of “average Englishman” ergonomics.
Fast forward to the post-war cycling boom. Competition bikes took a different path, slimming down to 130-140mm for aerodynamics. But when it came to broader markets—commuters, new hybrid bikes, and city cycling—the 160mm width morphed into the catch-all choice: wide enough for most, narrow enough for many.
As fit science and gender-specific designs grew in the late 20th century, brands started measuring sit bones and offering more widths. Yet even with all the new data, 160mm clung on as the “default,” especially in showrooms and online shops. A 2015 industry study actually found that most comfort and general-purpose bikes came stock with a 160mm-wide saddle. Coincidence? Not quite.
How 160mm Became Cycling's “Safe Zone”
So, what made 160mm the go-to width for so many saddles? It comes down to more than just comfort:
- Retail Simplicity: Fewer widths to stock makes life easier for shops. 160mm hits the sweet spot for “most riders” and keeps the floor manageable.
- Marketing the Middle: “Unisex” or “universal” often means splitting the difference—so 160mm becomes the catch-all.
- Fit Tools Reinforce the Mean: While fit systems measure your sit bones, they tend to recommend a width that's just broad enough for the vast majority of adults—right around that magical 160mm mark.
But does this shortcut really serve everyone well? Here's a real-world insight: one large bike shop chain reviewed years of fittings and saw well over 50% of customers ride away on 160mm saddles, largely because that's what they had in stock and, “realistically, it gets the job done for most.”
The Downsides of Standardization—Who Gets Left Behind?
While having a default can be convenient, there's a hidden cost to all this standardization:
- Loss of Personalization: Riders with narrower or especially wide sit bones often don't get what they truly need. Instead, they make do—or special order something that fits “just them.”
- Women's Comfort Overlooked: Studies show women tend to have wider sit bones on average, and yet saddles wider than 165mm are still rare in the performance segment. No surprise, then, that women encounter more saddle-related issues when using these “universal” sizes.
- Innovation Stalls: When most customers settle for average, brands have fewer incentives to take risks with radical shapes, adjustability, or truly custom options.
Did you know? Of over 100 modern saddle models reviewed in 2022, fewer than 10% of high-performance options were sold in sizes wider than 165mm. That leaves a lot of riders compromising on comfort.
Riding into the Future: Custom and Adjustable Saddles on the Rise
Thankfully, the era of “one size fits all” may be fading. New brands and technologies are changing the game:
- Adjustable-Width Saddles: Some newer saddles, like those from BiSaddle, let you slide the saddle halves to suit your exact anatomy—no more being stuck with whatever's standard.
- 3D Printing for Custom Fit: Emerging companies now offer saddles shaped precisely for your body using pressure maps or even smartphone scans.
- Wider Range of Sizes: The rapid growth of women's cycling, endurance events, and off-road riding is pushing big brands to finally add broader widths and unique shapes to their catalogs.
Meanwhile, biomechanics research is showing how much our posture, pelvic tilt, and riding style should shape our saddle choices—making it clearer than ever that the “average” just isn't enough.
Conclusion: Find Your Own Fit—It's Never Been Easier
The 160mm saddle has served as a trusty default for decades. And for riders squarely in the middle of the bell curve, it's probably “good enough.” But as our understanding of bodies, technology, and the diversity of cycling grows, it's time to move beyond averages and toward personalized comfort.
Whether you're dreaming of a long adventure, chasing race-day speed, or just craving a pain-free commute, the best saddle for you might be wider, narrower, or simply more adjustable than what you've tried before. One thing's certain: the future of saddle comfort is about riding your own line—not just settling for what comes standard.
